What you said at the end of this video is pure gold. People don't understand how important good tires really are. My dad has a 4wd Silverado and he recently got new tires and before he'd spin the tires so easily going uphill on wet pavement, now he has no problems. I applaud you on explaining that haha
Ya 2WD trucks do have their limitations, but with a locker and good driving skills you can surprise a lot of people. But don't even pay attention to people like that, if you've built a good rig yourself and you're proud of it that's all that matters.
Thanks for the video! The G80 is a solid traction device, if you don't subject it to explosive shock. They can't handle drag racing or higher horsepower power-plants. With that being said, they are great for a daily driver; I have one in my 86' two wheel drive C10 Chevy and it has saved me during a few bad winter storms. Again... I enjoyed the various driving conditions that you demonstrated the G80 in...!
I have a G80 in '93 4x4 Sonoma. It works for what it's intended for. It's gotten me out of several iffy situations when it snowed here in WA last year. I'm impressed by it.
This is most ASSUREDLY the absolute best video EVER made concerning and explaining the G80! In fact, this is probably the best video ever made PERIOD explaining ANY mechanical aspect of ANY vehicle! WELL DONE SIR JUST WELL DAMN DONE!!!!! I am in complete AWE after watching this and the entire time it was unfolding in front of my eyes I couldn’t believe what I was watching. I couldn’t believe someone had actually taken the time to do what you did! I was shell shocked to be honest. I am equally as stunned at the lack of views this video has garnered considering the sheer amount of arguing and misinformation being spread over the last 20 years when ALL of the answers could be found right here!!! You should have 1,000,000+ views easy!!! I am going to do my part and plaster this video everywhere I can and I can only hope it snowballs out of control and you get rich beyond your wildest dreams because of it! If so, you would absolutely deserve it!!! Just an incredible video my friend, just well above and beyond anything I have ever watched :)
I got a whole g80 rear end out of a junk yard got 120 bucks which I think is a steal for me and the fact that my 10 bolt open diff I have ate the spider gears.. Put a new set of spider gears in and the main center pin broke and wrecked the whole rear end.. So gettong a 10 bolt g80 for that much was great.. It has got me through freshly ripped ground for a new subdivision that was nothing but mud.. I cruised right on by my co worker who was stuck in his 4x4.. like you said in the video momentum got me through. My dad taught me about that before I was even old enough to drive.. If you know what you are driving through and it's safe to hit it hard and stay in the gas do so! My coworker was pissed that my 2wd 1500 5.3 pulled him out of the same mud i crawled right on through.. In fact I've surprised a lot of people with my ole girl.. Shit my truck has surprised the hell outa me a few times.. She's never left me stuck.. I give that to knowing how to drive in mud and the g80 rear end. I've heard a lot of bad things about the g80 but so far it's been good to me. I don't mess around when it's dry but if the roads are wet I like to have fun sometimes
G80 is a great unit in a 2WD truck. Sounds like you know the limitations of your truck and you don't put it in situations where you know it will get stuck easily.
I know I'm late to the party by a cple years, but' I live in N.E and never owned 4x4 til recent, (only because I needed a new truck), I never got stuck or stranded, good driving sense is perfectly worded.
Had this on my 05 GMC Sierra. I used to play with that all the time, no I never beat on it, I would just stop on a hill that hadn't been plowed from the snow yet. I traded it in in May for a 2015 Off Road Tacoma with a electronic locking Diff. We'll see how it works out this winter. Thanks for the video
Hell yeah *****. Mine is tough as hell. Now, I wouldn't put one wheel on the mud and one on concrete, rev the motor to 6000 and dump it from park to drive, but it will take a LOT of abuse. I don't beat my truck now, I've rebuilt all the old stuff and now I trail ride and go fairly easy... Take it easy man.
This particular locker is available from factory with a lot of GM trucks. If you're looking for something like it I'd go talk to your local transmission shop and see what they recommend. I like Eaton products in general, I had an LSD unit in my Camaro and I loved it.
Just picked up an old gem from 2008 with locking rear diff.....thanks for making a video doing all the shit I don't plan on attempting lol. Grew up in the 1990s driving shitty S10 pick ups in snowy Michigan, so I should be able to get through mild central Ohio winters if you're doing all that.
@@AnthonyJ350 it's also amazing what a few sand bags and dropping into first or second gear does for snowy conditions. Technology is great, but skill is always handy
I have an 02' Blazer ZR2 & that G80 does great in the sand at low speeds. It does lock up hard! If you jack up that rear & put it in neutral. That passenger side wheel will spin & bam! That drivers side is locked up, then unlocks & it'll lock back up again & repeat. I have 300k miles on mine. I think they are better on a 4x4. My ZR2 will go just about anywhere a Jeep Wrangler will go.
It's been a great locker for sane use and not overly abusive burnouts, but I do agree, for fast corners and drifting, it's not the right piece of equipment. I don't intend to swap it out, but if I did, I'd go for a detroit locker. Yes, they ratchet, but they also work on ice, unlike an eaton true-trac. With tires no bigger than 255, I think you can also use the 10-bolt for a lot of abuse.
I know! When you try to slide the truck it acts like an open diff half the time (except in the snow). Very unpredictable at speed, but it's not designed for that.
Well I have to say those things so you're aware. Butttt it's my truck and I still have to have fun in it when I make these videos. If I break it, it's my own problem. I just want people to be aware of both sides of the coin. I think that's fair.
I had a two wheel drive Silverado and when we had a bad ice storm I could go up hills with no problem when guys with four wheel drive were having all kinds of problems . Now I know why ! Also the truck just had regular all season tires on it .
selective air lockers are bomb thats what i got on my 71 ford e100 clubwaggon with a 347stroker and 88mm turbo setup, 1200whp 1200ftlb of torque at 32psi of boost, 3 speed on the tree and a ford 9 inch you want posi just press a botton and boom both rear wheels spin the same no mater what all the time want to turn them off when your not doing burn outs racing and drifting just press the botton dont know why peaple dont use this more i always see welded diffs and limited slip barley ever see setups like mine this setup makes the most sense to me, g80 is always engaging and disengageing becouse its automatic witch makes no sense it should be selectable
I’ve had trucks with both these and a Detroit locker in the rear. The G80 is a great stock differential although after having the Detroit for years there is just no comparison. The Detroit locks up so instantaneous, you’d never even know. But for a stock type locker, the G80 is definitely appreciated.
The G80 for sure is a great unit, it does a lot in low traction situations and is installed in millions of trucks. But we can't expect it to be as durable as a Detroit Locker. The G80 is fine for 90% of people out there.
i've never had a big enough bank account to be able to afford to abuse anything. the G80 is an absolute must. a truck without it to me is almost worthless.
I had one of these G80 differentials in my S10. It broke some teeth off the little gear thingy do hickey. Started making annoying clicking noise and I don't think it was even working at all because I got stuck on wet grass. They aren't good for doing burnouts. If you have one and you beat on it,there's a good chance your gonna break it. It disengages after about 35mph anyway. It's alright if you're trying to pull a boat up a wet boat ramp or something that. The clutches wear out after 40-60k miles then it doesn't work that great. If your G80 is broken or worn out don't put another one in your rig. Get a Detroit true track.
True Trac is awesome, I would definitely do it front and rear in a mild 4X4. I went with Yukon Gears Duragrip because Im mostly on the street and it's better for certain ice situations ruclips.net/video/uVxLAoJZuOo/видео.html
Ya the truck serves me well. I'm in year 8 of owner ship. I can't even consider getting a newer one cause it drives so good and I don't have a payment! Here's a video with everything done to the truck. ruclips.net/video/Rxh7MVXQSPU/видео.html
You put a lot of work into this YT video. Thank you. The real-world examples are fantastic. You did way more to your G80 than I do to mine as it is a practical addition (I ordered it that way) to my K2500 Suburban as I have a ranch that is many, many miles off of paved roads and there are lots of washouts. I would think some aftermarket companies would be selling different counterweights to allow the G80 to engage sooner or stay engaged longer. Is there such a thing??
Not that I know of. I actually recently had the G80 swapped for a traditional clutch style LSD. I gave up a little bit of lock up ability but gained more predictably and better street performance because it's always engaged. ruclips.net/video/uVxLAoJZuOo/видео.html
Really good video, you're pretty thorough, methodical, easy to digest this way, thanks. As I was watching, contemplated what it makes happen - my view is, the 'best traction' point in a muddy situation where say, you just parked up and have to start off, is right then and there, ie before you ruin the turf under your drive wheels by spinning them. Now what this diff does, it locks when there is 100 rpm difference in the half-axle rotation speed? It's better than an open diff (chr**t, what isn't) but it DOES make you ruin that 'best bit' of traction by allowing initial wheelspin before it 'catches'. This seems clear from your experiments here? My view, we all ought to have electric motors in each wheel, and the ICE motor just charges a central core of batteries, and we even take the steam off the 85% wasteful thing (yup, a combustion engine makes a really good heater), and make it spin a turbine and charge batteries with that too. Then, you just punch in what you want it to synthesize - first, pretend to be a normal open diff - so it makes the wheels spin at any speed they want, just applies even electrical power. Then, we want locked 2wd or AWD, punch it in. If you have ever seen a central heating motorized valve - THAT is what we ought to have at each wheel. there, got it off my chest. Oh, and you can turn corners without using the steering wheel, just make the outer wheels turn faster than the inner ones, of the imaginary curve you want to follow. Anyway, liked your demos.
I have a 4wd gmc that has the g80, with all terrain tires it is a beast, can't wait to get some deep snow to play in with it, I won't be drifting it or doing burnouts though I don't want to risk grenading the rear end.
AnthonyJ350 yeah they still offer them my truck is a 2012, they're still an option on the 2018s, idk about the 2019, they're doing a major redisign, you should look up the 2019 silverado if you haven't already. I have mixed feelings about it.
Samuel Clark I agree with the shorter overhangs. Looks like a Ram and F150 put together. I'm interested to see if they do direct injection again or if they do the design with port and direct injection.
I'll check this out. But I had great fun on my old 02 1500 2wd. My only regret (or salvation) was not resetting the speed limiter. That LM7 wanted to keep going, and quickly.
The way I drive, the G 80 will last and it will be about all Id need for the amount of off roading I actually see, but good to know its there when you need it.
+Skeefoo Panama Look up the G80. I don't feel like explaining it again. If you don't believe me, write a concerned e-mail to EATON. I'll tell you it only engages when it sees a difference in a 100RPM between both wheels. Some situations it will act like an open diff.
No Trent, you didn't. And I'm a Chevy guy. There is no rear and in a 2wd that is going to out mud a truck with 4wd. Sorry. I have a g80 in mine. I know what I'm talking about.
where i go fishing most guys have to use 4wd to get the boats out of the water, my 4wd doesnt work and the lockers in the rear really help out when pulling the boat.
Steve. You don't know. A combo of a driver that really knows there rig can out drive the best rig and rookie driver. Or great driver that doesn't know the rig. I have multi 4x4 full size trucks and drive allot. But my 04 dakota in 2wd stock did better that allot of 4wd. Never over generalize on a public forum. I have g80 in the 1500 hd, 87 has LSD front and back, other 2 k10 are bone stock.
For domestic full size trucks they say some slip is neccessary to convert traction however limited slip vs fully locking; Having fully locking is more ideal for icy & snow to extreme tractionless scenarios. From full size pickups to even mid size G80 locking differential is considered to be the most preffered bec it locks completely at specified speeds detecting wheel spin & loss of traction. however nowadays they have electronic locking vs mechanical locking types. Getrag difs for example are predominantly electronically controlled however depending on the application electronic locking difs allow faster lockup & overall traction control where as mechanical lockers are more reliable. The issue with most electronic lockers especially used on full size trucks are that some owners forget to service fluids in their diff causing overheating & failure internally. That takes place during overloading above payload or pulling above manufacturer SAE certified recommended tow or hauling levels. As long as with most electronic controlled diffs this is serviced regularily or specific type of fluids are used for extended life before draining & refilling there should be no problem however with that being said G80 lockee is more than likely the most ideal diff & preferred in any full sizer nowadays. It has the least slippage however in extreme weather conditions G80 equipped with 4wd is preferred.
You are correct that the 8.5 ring gear is .5 inch smaller than a ford 9 inch ring gear. As far as overall strength the 9 inch center section is much stronger since the pinion has bearings that support both sides of the gear while the 8.5 pinion only has support on one side of the gear. Nice video.
+AnthonyJ350 I do not have any experience with aftermarket diff covers. From what I can tell it should add some strength to the 3rd member housing and gives the bearing caps a little extra pressure which should help decrease the chance of ring and pinion gear deflection. Usually aftermarket diff covers are a little bigger to increase the gear oil capacity, which I think is helpful. I think the people that will get the most benefit from the differential cover upgrade would be people that routinely use the axle for racing when the axle is getting very high stress loads put on it with very good traction at the wheels, like drag racing. That is my 2 cents for what it is worth.
People trash these so much, they work. Are they the a strongest out there, no not by any means but they work as they were intended to. I have 35s on my silverado mine is going good. I've done some light wheeling and mudding things works like a champ. For a dd truck like mine I like it.
g80 cant be beat. If you use it correctly it is great. Period. IF you are going to do burnouts and crazy 4x4 then no.. But as a solid rear diff for hunting and off roading , cant beat it.
-- Love the G80, yes don't clown around with it, but it's probably one of the best. Mechanical, NOT vacuum, or electrical (IE more reliable and cheaper to fix). And here's the thing you didn't know. Not all, but you want to check this, modern vehicles, the locker doesn't work in reverse. The G80 does.
@@AnthonyJ350 -- I don't know the percentage, but they're out there. I'll keep this story extremely short. I contacted a dealer maintenance dep to see if the G80 worked in reverse. He said: I've worked here 25 years and I don't know. Let me check. 20 minutes later, he calls back. Yup, he tells me. Course I tested it with blocks, it works. 2004 Tahoe Z71, I bought as a winter beater a few months ago, my first experience with this platform. Been a Jeep guy for 25 years.
Thanks! If you look at my car video playlist and click on the "Interceptor Prologue" video you can see the truck with the other set of rims. They really set off the truck.
On my 2005 Colorado is had the RPO code YD3, which said that is the driver selectable locking read differential. But the selecting must be automatic because I do not have a button or a switch. Mine is crew cab and 4x4.
I have the exact same truck, have you had any problems climbing in snow and a little bit of ice on a dirt road? I have Michelin LTX. Thanks, great video!
Either adapt ya driving so ya dont destroy it or remove and replace with a Eaton Truetrack limited slip which is what i reccomend. The truetrack is clutchless and is an all gear limited slip with no weird helical clutches to wear out and locking hooks to snap off or springs to break
good for you man glad it worked out. I gave up on clutch pack lsd's long ago the new generation of clutchless diffs are just leaps and bounds over anything else.
TheDman216 I went clutch because depending on how you set it, it can be more aggressive than helical. I also like I won't have to left foot brake in certain icy conditions. The wet grip on the street is much better than the G80 since it's always engaged. My 350Z I have a hellical gear style LSD installed.
@SnowBladerX That's cool. If this thing ever breaks I'm probably going to throw in an Eaton Truetrac. Like I mention in the video it is a low speed traction device, and I know where it's ok to spool it up, cause in snow or wet pavement it'll never get enough grip to grenade itself. On dry dirt probably would hurt it pretty bad. All I know is, this is what came in the truck, it's working and if it breaks, oh well. Do I condone behavior in my vid, not really but I'm having fun with it :)
Not to split hairs but unless you put an 8.5 in your truck what you have is an 8.6 which started in late 99, 8.5 was early 99 and prior, there's not a ton of difference but they are different; carrier journals,carrier bearings, and backing plate flanges for the most part
its not jus the size of fords 9", its the way its all setup, like the layout location n style of bearings along with placement n angle of the pinion and its bearing setup, a full floater is part of what makes a gm 14 bolt so once of my favorites to own, that n its tough as hell n simple n cheap to work on i also have a suburban with the same locker hes got in this truck here..basically im not even goin to say still runnin strong because i dont wanna hav to even have to knock on wood lol :p not takin chances with that :p
You may not know this answer because it’s many years ahead of this video, but I have a 2020 gmc savana 2500 6.0 Gas with stabilitrak and traction control. How does the G80 work in conjunction with that? Do you have to manually disengage it or does it do it automatically every time it engages? I’m naturally assuming it has to disengage, I can’t imagine it engaging with traction control limiting the spin :)
Great video, thanks. You were applying some power there. I honestly don't understand how this G80 mechanism lasts 5 minutes. That little centrifugal device is locking the spider gears INSTANTLY. What is stopping these things from immediately exploding all the time? Dave F. in RI
I don't know but GM has put them in A LOT of trucks. So for the average user it seems to be more than enough. I definitely push it harder than the "official" demonstration videos. But I'm pretty sure this one is the most fun to watch.
Hi, I just bought 1996 Chevy Z71 1500 with the 6.5 diesel in it and it came with the G80. I was wondering if it would hurt it if I was drifting corners on dirt roads and on lakes in the winter? Also what kind of gear oil should be in it?
It doesn't have clutches like a limited slip unit, it's a full mechanical locker, so you can use a quality synthetic gear oil with the appropriate weight. I just buy some from a credible transmission shop. Most shops will only charge you around 100 bucks and they deal with the mess and it's something you don't have to change often anyways. As for drifting it at speed, it's kind of hard because it only wants to engage at low speeds (under 30MP/H). You can slide it around at low speeds as I did in the video but that's about it. In my experience at higher speeds it's a little unpredictable and probably not good for it so I would try not to. If you're looking for an upgrade look into Eaton's TrueTrac.
Good video, I myself just purchased a jeep liberty sport 4wd and I want to do some trails after I get a nice set of all terrain tires! nice Viideo I like your truck thats actually crazy control for a 2wd truck. and I have learned the hard way that momentum is your friend! haha
Ya should be fine. G80s in half tons trucks will most likely see damage on pavement where there can be a sudden amount of traction. Offroad scenarios with modest throttle input I would say are fine.
My experience is when it is raining and one of the wheel spins too fast. You get a jolt than a Bang and then it starts moving. However if the wheel isn't spinning very fast it transitions smoothly. The problem is the faster spinning is the real world. Because you have the pull into fast moving traffic. There's no time to slowly pull out from the stop.
Ya it's truly a low speed traction device. I ended up having a shop put in a Yukon Gear Duragrip for abuse and better street performance. The preloaded clutch setup is so much better in the wet, since it's always engaged. It still has decent lockup off road ruclips.net/video/uVxLAoJZuOo/видео.html
You can not compare the gm 8.5 to a 9 inch at all... the reason the 9 inch can handle so much power is because it has a third bearing on the end of the pinion to virtually eliminate pinion gear deflection. Not saying the 8.5 can't take a beating, but the 9 is far superior.
Hi,Its not just only that Fords rearend ring gear is larger, Yes larger is better, Its that the ford 9 inch` has three bearings on its pinion. Giving its reputation of being bullet proof!
I always invest in the axles first, tires,gears,and selectable lockers, I even went w/Trailready beadlocks on my last project(a long wheelbase Ram).I pull a camper on the beach every year and Ive been stuck,and I hate to see others stuck,I always offer to help, but if its a big turbodiesel "Dually" I always chuckle a little. Itzagas w/a stick. Great video & explanation to offer others, now u should do a Wastegate & Blowoff valve difference for them?
I realize that I was commenting cause Diesel owners think they have the tuffest rigs out there , diesel engines are usually heaveier though (ISX-15Litre)
They're actually Timbren load cushions. Works really well when loaded. If you set them up too close to the axle the ride is a bit bumpy. I also run the RoadMaster Active suspension in conjunction with them and an extra leaf spring.

My ZR2 will go just about anywhere a Jeep Wrangler will go.
Thanks for sharing your experience!
It's been a great locker for sane use and not overly abusive burnouts, but I do agree, for fast corners and drifting, it's not the right piece of equipment. I don't intend to swap it out, but if I did, I'd go for a detroit locker. Yes, they ratchet, but they also work on ice, unlike an eaton true-trac. With tires no bigger than 255, I think you can also use the 10-bolt for a lot of abuse.
I know! When you try to slide the truck it acts like an open diff half the time (except in the snow). Very unpredictable at speed, but it's not designed for that.
Well I have to say those things so you're aware. Butttt it's my truck and I still have to have fun in it when I make these videos. If I break it, it's my own problem. I just want people to be aware of both sides of the coin. I think that's fair.
your best friend when offroading is a really tough winch, because 9 times outa 10 common sense goes right out the window
I had a two wheel drive Silverado and when we had a bad ice storm I could go up hills with no problem when guys with four wheel drive were having all kinds of problems . Now I know why ! Also the truck just had regular all season tires on it .
Thanks for sharing your experience! It's amazing what a traction device like this and some driver skill are able to do.
My 2015 Silverado LTZ 6.2 has the G80. It has towing package. AFM delete BTR cam LS7 lifters. She is a great truck.
Love that you did the AFM delete. It's going to be a very reliable truck.
selective air lockers are bomb thats what i got on my 71 ford e100 clubwaggon with a 347stroker and 88mm turbo setup, 1200whp 1200ftlb of torque at 32psi of boost, 3 speed on the tree and a ford 9 inch you want posi just press a botton and boom both rear wheels spin the same no mater what all the time want to turn them off when your not doing burn outs racing and drifting just press the botton dont know why peaple dont use this more i always see welded diffs and limited slip barley ever see setups like mine this setup makes the most sense to me, g80 is always engaging and disengageing becouse its automatic witch makes no sense it should be selectable
I’ve had trucks with both these and a Detroit locker in the rear. The G80 is a great stock differential although after having the Detroit for years there is just no comparison. The Detroit locks up so instantaneous, you’d never even know. But for a stock type locker, the G80 is definitely appreciated.
The G80 for sure is a great unit, it does a lot in low traction situations and is installed in millions of trucks. But we can't expect it to be as durable as a Detroit Locker. The G80 is fine for 90% of people out there.
Which Detroit? The trutrac?
@@805BeachRecoveries No, the actual Detroit locker.
@@AnthonyJ350 absolutely agree.
Reason I asked is I was under the impression the Detroit locker was a full time locker? So it shouldn't need to lock up, right?
i've never had a big enough bank account to be able to afford to abuse anything. the G80 is an absolute must. a truck without it to me is almost worthless.
I had one of these G80 differentials in my S10. It broke some teeth off the little gear thingy do hickey. Started making annoying clicking noise and I don't think it was even working at all because I got stuck on wet grass. They aren't good for doing burnouts. If you have one and you beat on it,there's a good chance your gonna break it. It disengages after about 35mph anyway. It's alright if you're trying to pull a boat up a wet boat ramp or something that. The clutches wear out after 40-60k miles then it doesn't work that great. If your G80 is broken or worn out don't put another one in your rig. Get a Detroit true track.
True Trac is awesome, I would definitely do it front and rear in a mild 4X4. I went with Yukon Gears Duragrip because Im mostly on the street and it's better for certain ice situations ruclips.net/video/uVxLAoJZuOo/видео.html
Great video, thanks for taking the time to talk about the G80 and show some demonstrations
Thanks for watching!
for being 2wd with diff lockers it seems good no matter where you take it
Ya it is. It's very limited in muddy conditions so you have to be a smart driver. Like don't go into deep mud with it lol.
Man, you put that Silverado through its paces! Cool video!
Ya the truck serves me well. I'm in year 8 of owner ship. I can't even consider getting a newer one cause it drives so good and I don't have a payment! Here's a video with everything done to the truck. ruclips.net/video/Rxh7MVXQSPU/видео.html
Good driving through the mud! Sadly I know people with lifted 4x4s that would get stuck in that
Thanks!
You put a lot of work into this YT video. Thank you. The real-world examples are fantastic. You did way more to your G80 than I do to mine as it is a practical addition (I ordered it that way) to my K2500 Suburban as I have a ranch that is many, many miles off of paved roads and there are lots of washouts. I would think some aftermarket companies would be selling different counterweights to allow the G80 to engage sooner or stay engaged longer.
Is there such a thing??
Not that I know of. I actually recently had the G80 swapped for a traditional clutch style LSD. I gave up a little bit of lock up ability but gained more predictably and better street performance because it's always engaged.
ruclips.net/video/uVxLAoJZuOo/видео.html
Really good video, you're pretty thorough, methodical, easy to digest this way, thanks. As I was watching, contemplated what it makes happen - my view is, the 'best traction' point in a muddy situation where say, you just parked up and have to start off, is right then and there, ie before you ruin the turf under your drive wheels by spinning them.
Now what this diff does, it locks when there is 100 rpm difference in the half-axle rotation speed? It's better than an open diff (chr**t, what isn't) but it DOES make you ruin that 'best bit' of traction by allowing initial wheelspin before it 'catches'. This seems clear from your experiments here?
My view, we all ought to have electric motors in each wheel, and the ICE motor just charges a central core of batteries, and we even take the steam off the 85% wasteful thing (yup, a combustion engine makes a really good heater), and make it spin a turbine and charge batteries with that too.
Then, you just punch in what you want it to synthesize - first, pretend to be a normal open diff - so it makes the wheels spin at any speed they want, just applies even electrical power. Then, we want locked 2wd or AWD, punch it in. If you have ever seen a central heating motorized valve - THAT is what we ought to have at each wheel.
there, got it off my chest. Oh, and you can turn corners without using the steering wheel, just make the outer wheels turn faster than the inner ones, of the imaginary curve you want to follow. Anyway, liked your demos.
Thanks for sharing your insight on things
I have a 4wd gmc that has the g80, with all terrain tires it is a beast, can't wait to get some deep snow to play in with it, I won't be drifting it or doing burnouts though I don't want to risk grenading the rear end.
Samuel Clark I believe the G80 is still being used in the newer GM trucks as well.
AnthonyJ350 yeah they still offer them my truck is a 2012, they're still an option on the 2018s, idk about the 2019, they're doing a major redisign, you should look up the 2019 silverado if you haven't already. I have mixed feelings about it.
Samuel Clark I agree with the shorter overhangs. Looks like a Ram and F150 put together. I'm interested to see if they do direct injection again or if they do the design with port and direct injection.
AnthonyJ350 I just hope they keep the 4.3s and 5.3s around, they are reliable, wouldn't mind seeing a turbo v6 option to compete with the ecoboost
Samuel Clark Ya me too
I'll check this out. But I had great fun on my old 02 1500 2wd. My only regret (or salvation) was not resetting the speed limiter. That LM7 wanted to keep going, and quickly.
What's the lm7?
+brad brown 5.3l V8.
+high life 1320 o true that. Thanks. they are super powerful and reliable. my uncle has a 03 gmc sierra z71. with 276k miles with original 5.3.
The way I drive, the G 80 will last and it will be about all Id need for the amount of off roading I actually see, but good to know its there when you need it.
+Skeefoo Panama Look up the G80. I don't feel like explaining it again. If you don't believe me, write a concerned e-mail to EATON. I'll tell you it only engages when it sees a difference in a 100RPM between both wheels. Some situations it will act like an open diff.
Good video, with quality information in the narrative. Personally, I'm a Ford guy but your Silverado sounds terrific and goes really well. Nice truck!
Thank you!
I have the 9.5 simifloat version. Good luck on breaking that. The 3/4 ton HD Silverado's have all the good parts.
Good to know! I plan to get a 3/4 ton for my next truck.
awkward moment when you are driving a chevy in 2wd and you go through holes that fords and dodges cant do in 4wd.
Hahaha, can't say I haven't had that pleasure yet.
AnthonyJ350 ya i did it in my 5 tonne truck that 2wd.
No Trent, you didn't. And I'm a Chevy guy. There is no rear and in a 2wd that is going to out mud a truck with 4wd. Sorry. I have a g80 in mine. I know what I'm talking about.
where i go fishing most guys have to use 4wd to get the boats out of the water, my 4wd doesnt work and the lockers in the rear really help out when pulling the boat.
Steve. You don't know. A combo of a driver that really knows there rig can out drive the best rig and rookie driver. Or great driver that doesn't know the rig. I have multi 4x4 full size trucks and drive allot. But my 04 dakota in 2wd stock did better that allot of 4wd. Never over generalize on a public forum. I have g80 in the 1500 hd, 87 has LSD front and back, other 2 k10 are bone stock.
Ya it was. Got it pretty stuck initially in that uphill mud scene lol. That rwd civic of your is pretty killer btw!
We have this on our 2015 4wd Dually works great towing across the sand dunes.
Nice!
For domestic full size trucks they say some slip is neccessary to convert traction however limited slip vs fully locking; Having fully locking is more ideal for icy & snow to extreme tractionless scenarios.
From full size pickups to even mid size G80 locking differential is considered to be the most preffered bec it locks completely at specified speeds detecting wheel spin & loss of traction.
however nowadays they have electronic locking vs mechanical locking types.
Getrag difs for example are predominantly electronically controlled however depending on the application electronic locking difs allow faster lockup & overall traction control where as mechanical lockers are more reliable.
The issue with most electronic lockers especially used on full size trucks are that some owners forget to service fluids in their diff causing overheating & failure internally.
That takes place during overloading above payload or pulling above manufacturer SAE certified recommended tow or hauling levels.
As long as with most electronic controlled diffs this is serviced regularily or specific type of fluids are used for extended life before draining & refilling there should be no problem however with that being said G80 lockee is more than likely the most ideal diff & preferred in any full sizer nowadays.
It has the least slippage however in extreme weather conditions G80 equipped with 4wd is preferred.
+Muhammad M Salaam True that. ive have a 2wd mechanical g80. Better than having just an open diff. You know your stuff a lot of people dont
the very last thing you said is absolutely true nice ram-bar on the front.
+Grant Carter Thanks!
I have a 2001 Silverado with g80 locker , all terrain tires and lift kit. Thing is really capable off road.
It's pretty good for a factory part!
I am and always have been a hardcore Ford guy. But I can honestly say, nice truck man. Looks and sounds good. 👍
Widowmakermowers Pennsylvania Thanks! Still have it, we just changed out all the cab mounts.
Great driving skills!!!!! Now was that a demo of abusing that diff or were those demos of how it was intended to be used?
Anything low speed was how it was intended to be used. Anything high speed was abuse.
You are correct that the 8.5 ring gear is .5 inch smaller than a ford 9 inch ring gear. As far as overall strength the 9 inch center section is much stronger since the pinion has bearings that support both sides of the gear while the 8.5 pinion only has support on one side of the gear. Nice video.
+flapjackthemermaid Thanks. Does it help that I run a T/A diff cover that has bearing caps for support though? As opposed to the stock stamped piece.
+AnthonyJ350 I do not have any experience with aftermarket diff covers. From what I can tell it should add some strength to the 3rd member housing and gives the bearing caps a little extra pressure which should help decrease the chance of ring and pinion gear deflection. Usually aftermarket diff covers are a little bigger to increase the gear oil capacity, which I think is helpful. I think the people that will get the most benefit from the differential cover upgrade would be people that routinely use the axle for racing when the axle is getting very high stress loads put on it with very good traction at the wheels, like drag racing. That is my 2 cents for what it is worth.
Brutal that that thing just kicks in all of a sudden..
As far as factory equipment it's pretty nice to have compared to a LSD unit.
People trash these so much, they work. Are they the a strongest out there, no not by any means but they work as they were intended to. I have 35s on my silverado mine is going good. I've done some light wheeling and mudding things works like a champ. For a dd truck like mine I like it.
Looks like you had lots of fun making this video!
It definitely was!
Nicely done!
Thanks!
g80 cant be beat. If you use it correctly it is great. Period. IF you are going to do burnouts and crazy 4x4 then no.. But as a solid rear diff for hunting and off roading , cant beat it.
Yes, it is very versatile for factory equipment.
-- Love the G80, yes don't clown around with it, but it's probably one of the best. Mechanical, NOT vacuum, or electrical (IE more reliable and cheaper to fix). And here's the thing you didn't know. Not all, but you want to check this, modern vehicles, the locker doesn't work in reverse. The G80 does.
Oh that's really interesting, I didn't know a lot of factory lockers don't work in reverse. I'll have to look into that.
@@AnthonyJ350 -- I don't know the percentage, but they're out there. I'll keep this story extremely short. I contacted a dealer maintenance dep to see if the G80 worked in reverse. He said: I've worked here 25 years and I don't know. Let me check. 20 minutes later, he calls back. Yup, he tells me.
Course I tested it with blocks, it works. 2004 Tahoe Z71, I bought as a winter beater a few months ago, my first experience with this platform. Been a Jeep guy for 25 years.
Good explanation, great video,and nice job handling that truck,keep the great job.
Thanks for watching!
Nice speech at the end haha. Makes sense!! :)
Haha thanks!
Thanks! If you look at my car video playlist and click on the "Interceptor Prologue" video you can see the truck with the other set of rims. They really set off the truck.
On my 2005 Colorado is had the RPO code YD3, which said that is the driver selectable locking read differential. But the selecting must be automatic because I do not have a button or a switch. Mine is crew cab and 4x4.
I think only Hummer H2's had the button for the selectable locker.
I have the exact same truck, have you had any problems climbing in snow and a little bit of ice on a dirt road? I have Michelin LTX. Thanks, great video!
Not really cause I put a little weight in the back and now I run winter tires with studs in the winter season.
Gorgeous Silverado
Either adapt ya driving so ya dont destroy it or remove and replace with a Eaton Truetrack limited slip which is what i reccomend. The truetrack is clutchless and is an all gear limited slip with no weird helical clutches to wear out and locking hooks to snap off or springs to break
TheDman216 After 9 years of service with the G80 problem free, we changed to a 3.73 ring gear and a Yukon Gear duragrip clutch style LSD.
good for you man glad it worked out. I gave up on clutch pack lsd's long ago the new generation of clutchless diffs are just leaps and bounds over anything else.
TheDman216 I went clutch because depending on how you set it, it can be more aggressive than helical. I also like I won't have to left foot brake in certain icy conditions. The wet grip on the street is much better than the G80 since it's always engaged.
My 350Z I have a hellical gear style LSD installed.
You're a good driver. Good job.
Thank you!
Do you find the turning radius is compromised with Detroit locker? (As far as daily drivers go) wouldn't the TruTrac be a better choice?
@SnowBladerX That's cool. If this thing ever breaks I'm probably going to throw in an Eaton Truetrac. Like I mention in the video it is a low speed traction device, and I know where it's ok to spool it up, cause in snow or wet pavement it'll never get enough grip to grenade itself. On dry dirt probably would hurt it pretty bad. All I know is, this is what came in the truck, it's working and if it breaks, oh well. Do I condone behavior in my vid, not really but I'm having fun with it :)
Not to split hairs but unless you put an 8.5 in your truck what you have is an 8.6 which started in late 99, 8.5 was early 99 and prior, there's not a ton of difference but they are different; carrier journals,carrier bearings, and backing plate flanges for the most part
its not jus the size of fords 9", its the way its all setup, like the layout location n style of bearings along with placement n angle of the pinion and its bearing setup, a full floater is part of what makes a gm 14 bolt so once of my favorites to own, that n its tough as hell n simple n cheap to work on i also have a suburban with the same locker hes got in this truck here..basically im not even goin to say still runnin strong because i dont wanna hav to even have to knock on wood lol :p not takin chances with that :p
Thanks for your insight! I think a lot of people respect these axles now with some many turbo charged Silverado running around now.
Thanks! It's got JBA headers & Magnaflow exhaust on it with a K&N FIPK.
You may not know this answer because it’s many years ahead of this video, but I have a 2020 gmc savana 2500 6.0 Gas with stabilitrak and traction control. How does the G80 work in conjunction with that? Do you have to manually disengage it or does it do it automatically every time it engages? I’m naturally assuming it has to disengage, I can’t imagine it engaging with traction control limiting the spin :)
Should be fully automatic still
That’s cool. There’s a lot of 2wd vehicles that would definitely not be able to do that. Probably some awd ones too.
There's definitely a lot of limitations for a 2WD truck. Just have to understand what they are and avoid those situations.
Great video, thanks. You were applying some power there. I honestly don't understand how this G80 mechanism lasts 5 minutes. That little centrifugal device is locking the spider gears INSTANTLY. What is stopping these things from immediately exploding all the time?
Dave F. in RI
I don't know but GM has put them in A LOT of trucks. So for the average user it seems to be more than enough. I definitely push it harder than the "official" demonstration videos. But I'm pretty sure this one is the most fun to watch.
Hi, I just bought 1996 Chevy Z71 1500 with the 6.5 diesel in it and it came with the G80. I was wondering if it would hurt it if I was drifting corners on dirt roads and on lakes in the winter? Also what kind of gear oil should be in it?
It doesn't have clutches like a limited slip unit, it's a full mechanical locker, so you can use a quality synthetic gear oil with the appropriate weight. I just buy some from a credible transmission shop. Most shops will only charge you around 100 bucks and they deal with the mess and it's something you don't have to change often anyways.
As for drifting it at speed, it's kind of hard because it only wants to engage at low speeds (under 30MP/H). You can slide it around at low speeds as I did in the video but that's about it. In my experience at higher speeds it's a little unpredictable and probably not good for it so I would try not to. If you're looking for an upgrade look into Eaton's TrueTrac.
Good video, I myself just purchased a jeep liberty sport 4wd and I want to do some trails after I get a nice set of all terrain tires! nice Viideo I like your truck thats actually crazy control for a 2wd truck. and I have learned the hard way that momentum is your friend! haha
Thanks for watching!
perfect explanational video. I just found out tonight that my 98 z71 has a g80.
Thanks for watching!
Would you consider "Up Hill on Mud" within the working parameters of the G80 or abuse of it? Thank you.
Ya should be fine. G80s in half tons trucks will most likely see damage on pavement where there can be a sudden amount of traction. Offroad scenarios with modest throttle input I would say are fine.
Love the sound of that 5.3 :)
It's a 4.8L V8 😉 It's got a cam now and a TBSS intake and we stepped the exhaust up to a 3 inch.
so how dose this work is it full time locked so tyres skuff when turning. or is it more like a lsd that locks when it feels lots of slip cheers
That’s rad actually
Thanks for watching 🙂
Great tip!
Great Video, Nice demonstrations bet you has tons of fun doing it..haha
Fernando Cornejo Ya I won't lie, it's entertaining to do stuff like this.
G80s aren't meant to be abused. They are as the guy in the video said, it's a low speed traction diff. You have to know its limits.
My experience is when it is raining and one of the wheel spins too fast. You get a jolt than a Bang and then it starts moving. However if the wheel isn't spinning very fast it transitions smoothly. The problem is the faster spinning is the real world. Because you have the pull into fast moving traffic. There's no time to slowly pull out from the stop.
Ya it's truly a low speed traction device. I ended up having a shop put in a Yukon Gear Duragrip for abuse and better street performance. The preloaded clutch setup is so much better in the wet, since it's always engaged. It still has decent lockup off road ruclips.net/video/uVxLAoJZuOo/видео.html
Thanks, ya that's the gear ratio my truck came with.
Good video man, no BS
Thanks man!
I don't see how, the G80 is purely a mechanically engaged unit.
You can not compare the gm 8.5 to a 9 inch at all... the reason the 9 inch can handle so much power is because it has a third bearing on the end of the pinion to virtually eliminate pinion gear deflection. Not saying the 8.5 can't take a beating, but the 9 is far superior.
Hi,Its not just only that Fords rearend ring gear is larger, Yes larger is better, Its that the ford 9 inch` has three bearings on its pinion. Giving its reputation of being bullet proof!
But to be fair this rear end holds its own. There's so many turbo charged trucks out there where they leave the rear end alone.
Volvo 740/940/960s apparently came with these past 1991. No wonder they can plow through shit.
Really?! Learned something new
Damn thats a mean sounding 4.8
I always invest in the axles first, tires,gears,and selectable lockers, I even went w/Trailready beadlocks on my last project(a long wheelbase Ram).I pull a camper on the beach every year and Ive been stuck,and I hate to see others stuck,I always offer to help, but if its a big turbodiesel "Dually" I always chuckle a little. Itzagas w/a stick. Great video & explanation to offer others, now u should do a Wastegate & Blowoff valve difference for them?
+forcefed38 That's a good suggestion for a future video.
I realize that I was commenting cause Diesel owners think they have the tuffest rigs out there , diesel engines are usually heaveier though (ISX-15Litre)
The 10.5 is pretty sturdy even at high speed
Ya it been a great rear axle so far.
Would you recommend the g80 for occasional snow drifting? Or should I go with an Lsd?
Supralars Snow drifting LSD is way more predictable. Either an Eaton Trutrac or Yukon Duragrip. I just put a Duragrip in my truck recently.
I'm just in the middle of a Diablo Sport video, there's an awesome brake stand in it, and one of my "Angels" also guest stars in it ;) Stay tuned!
How did you get your tail lights to alternate between the brake bulb and the marker bulb when flashing?
92MikeKY It's just how the truck work from factory when the parking lights are on.
For the record you have a 8.6 rear, the 8.5 was used up until 99.
Thanks for the spec. correction!
+AnthonyJ350 you're a good driver. Thanks for the informational video!
Thank you!
If you are looking for something like a LSD on the cheap and don't mind being locked in all the time with no way of unlocking look into a mini spool.
Sounds like it wouldn't be that great on the street or high speed on turns on the highway in the wet.
Great video
Thanks! You might find this video interesting as well ruclips.net/video/uVxLAoJZuOo/видео.html
I see your truck has air bags how does it ride with those added
They're actually Timbren load cushions. Works really well when loaded. If you set them up too close to the axle the ride is a bit bumpy. I also run the RoadMaster Active suspension in conjunction with them and an extra leaf spring.
It's actually a 4.8L with full exhaust.
