LOL - glad we could share it with you and yes, for how much it costs and how much things can be done wrong, this really is something best left to people who do it all the time.
Appreciate you two coming all the way out to see us and trusting us with your gears! Always a great time with you guys and glad you are enjoying that 8th gear again 😎
Are you kidding?! Having had previous experiences dealing with shops who really screwed things up, you guys are one of the very few across America that I would trust to work on our Jeeps! That is no lie! Of course, we always have a great time with you and Chad and always appreciate your attention to detail. 8th gear at a nice low RPM at highway speeds has been awesome to have again 👍
Did you have a shop in Florida 😢 or do I need to drive there. Crazy lot of work but clearly show how hard the work is and how easy someone can f things up Thanks for making the video.
Jeep Master Tech here. The struggle is real with JL/JT diff. side bearings! I’ve had to cut them off on every re-gear I’ve ever done, at least a couple dozen now. The first one I did I tried using the Jeep special tool designed to pull these bearings off and the bearing race exploded sending shrapnel onto my hand. I just cut them all now. Also, the ring gear bolts need to be torched to loosen the thread locker as it’s ridiculously strong and the bolt heads are ridiculously small.
I re-geared my 2020 Willy's that has 35's on it to 4.88. It made all the difference in the world on that jeep. I thought it may have been too much gear but I thought I could increase it to 37's but no need. Accelerates so much better, driveability in town and on the highway. I did it myself and actually really enjoyed doing it. But it was a lot of work and I get why it's so expensive. I used the revolution gears and they set up very nice. Great cuts and centered well with a good pattern. Good video and I think with oversize tires that so many jeeps have installed the gears are the best modification you really have to make! I used BFH garage channel to get through any gotchyas for the metric axles.
The gear change is one of the best mods I've done,running 37x12.5x17 at a 5.13's, aswome power 8th gear all day long and towes perfect 👍,4 low is amazing
Yup, having run that setup in the past, I can agree with what you've said. The only downside is that you run on the high side of RPM at highway speeds.
I regeared my 2021 Jeep Gladiator Max Tow to 4.88 with 37 inch tires. It’s a much improved truck now. The 4.10 gears struggled. I hardly ever saw 8th gear. I would be in 5th gear on the highway if there was strong head wind and a slight incline. The 4.88 gears brought my Jeep back to stock. Smooth shifting and a much more enjoyable experience.
Woah, 13 mph!! I have a 2020 gladiator Rubicon Launch edition on 33's that is getting 18.6 to 19.2 average mph. You must be driving your jeep like you stole it. The shop that did this install is clearly top notch. Thanks for the video.
I like the thorough job these brothers are doing. Very thorough and do it right the first time is how I like. Great job! I absolutely enjoy watching this whole video. Will definitely keep this shop on my A list.
After watching this video I’ll definitely hit them up for a regear. Amazing work and knowledge and true craftsmanship. And best of all, they’re only 1.5 hrs away from me! Woo!! Awesome video gents
Eddie, that was a fantastic video. Jeremy was amazing with a wealth of knowledge with a clear way of putting it all out there. Thanks for your efforts; you both have clarified much.
I’m about to regear my JL sport unlimited to 4.56s! I’m excited. Perfect timing for this video to come out I’m running 315 70 17 3.6L 8 speed automatic
Great video and I enjoyed the input on gear ratios versus tire size. A lot of people just want a simple chart on what gears with a certain size tire, but there are so many variables to consider when picking gear ratios in addition to tire size. Things like tire weight, weight of vehicle, towing, engine, transmission, vehicle use, etc. should be factored when picking a ratio. My JT 3.6 auto is a daily driver with frequent highway miles and no towing. I chose 4.56 gears and they work great with my 35 inch load C AT tires! Thanks again for the very informative video!
Nice work by those guys! Good attention to detail, and knowing their job! I had my TJ re-geared years ago by a shop here in silicon valley and they really screwed up the installation of new gears and an ARB. I took it to another local shop who did what they could to straighten out the sloppy work. But its never been totally right since. The rear end is now making slight noises.... I may end up taking my TJ to Hanford this winter to have the rear end re-done. Thanks for the video!
Let me guess, the shop in question forgot or didn't know to cut drain slots on the axle tubes and you fried your bearings. Either way, Disciple should be able to help you out.
Thank you for the insight. I have a 2018 Wangler Rubicon with a 3.6. I have 35's on my Jeep. I will be towing occasionally, so I think 488 will be good for me. Thanks!
I have a friend who has a 2023 Mojave with 38's (Nitto Ridge Grapplers) and stock 4.10 gears. he drives it pretty "chill" and takes it offroad, but still gets 8th gear on flat roads, but mostly useless. Truck seems to drive really well as is, but has Banks Pedal Monster which doesnt give more power, but throttle response is 1000% better.
a 3.8 with 4.10s and an automatic meaning 4 gears can also push 37s I cant believe the 3.6 with eight gears still isnt doing any better 😒 Good video, I really like the content ya got I learn so much👌
For those of you wondering why the pinion gear has to get smaller as the gear ratio gets bigger 3:73 to say a 5:13 is because the housing is only so big. If the housing could fit a bigger ring gear, the pinion wouldn’t need to be smaller, but since the housing is only so big, the pinion is what gets smaller.
@@wayalife I do have one question. Apologies if it's a complicated question. I'm basically in a very similar scenario to the JT you just had re-geared, 4.5" lift and 37s. I've been debating what gear ratio to install. I have steel bumpers front and back, winch, armored side steps, a heavy steel bed rack... But more importantly I also live and operate my JT at pretty high altitude: 7,500+ ft. Is this a case for a bit of a higher gear ratio than the 4:88? I'm not going to be doing a lot of interstate driving. A lot of mountain passes, camping, maybe towing an occasional pop up camper, etc. I'd be curious what your thoughts were? Thanks!
The extra weight you have wouldn't get me to want a higher ratio and while I'm not at the same altitude as you, I do live at 4500 and the mountains I live next to and travel across on a somewhat regular basis gets up close to 8000. None of this is a problem for me with 4.88. That said, if you do plan on towing, the extra power that 5.13s provide would be worth having.
@@wayalife Thank you! Your real world experience is valuable. It's a big investment that I don't want to have to redo... So all information I can gather to make an informed decision is a plus. Really appreciate it!! 🙌
Fascinating - Excellent and informative video, love this. I have so much back lash in the drive line of my brand new Gladiator, wonder if the diffs aren’t set well from factory.
Long way from Nv. Eddie! Haha. Have never been to Disciple Off Road, but they used to be close when I was in Fresno... now in Idaho and that's just a bit too far! Lol. Thanks for the video. 👍
@@wayalife awwww dang Jet was my favorite besides Moby we were building my parents 2018 Jeep JLUR simultaneously to Jet but I do love the 392 and the new JT
Agreed! My 2019 JLUR on 37's never went into 8th gear. Switched to 5:13's & has great acceleration & goes into 8th gear easily. I was worried that 5:13's would be too steep, but cruises great on the highway at about 2600 RPM at 75 MPH
Yup, sounds about right to me and the power is fun to have. That said, 2600 rpm at 75 mph is way higher than what I'd prefer to have this Gladiator running at. Of course, that's just me.
2600 is a tad bit too much bud! 75 might be the speed limit in areas you live, but you need to really keep it close to 2300 for gear change and cruise at about 1900,2100. These trucks really hold onto gears on ascends so when going up just keep your foot as still as you can and it’ll stay in gear and get you over the hill. In long ascends I’m in 6th at about 2200 and I ease back into 7th once we’re over the top.
I just want to add, for my older 2007, with the 3 speed/OD and 3.8, the Rubicon 4 door with stock 32s struggled on the freeway. Once I updated to 35x12.50's it was terrible. I upgraded to 5.13s and it was perfect, better than stock by a few hundred rpms. Absolutely Perfect for the original JKs, I put at least 80K on those gears no issues. I sold that in 22 after I bought my 21 4XE. I find it interesting with my 21 4XE Sahara with 35's (ARB Air locker, lifted, build out, etc.) and feel zero need to upgrade. The 2.0 has so much torque+Electric I don't even notice the difference. And my fuel, around town with 70 mile trip a week is at 35 MPG, my old 07, I was lucky to get 12 mpg. Oh and for me in AZ, Desert Rat has done all my gearing for the JK and locker for the 4xe. Perfect jobs, no issues.
As I state in the video, the all new 8-speed automatic transmission is totally up to the job of pushing bigger tires and at just 35", I wouldn't bother regearing.
@@wayalife the more I've thought about this video the more I realize just how educational and helpful this video is. Much gratitude for your time, work and skill at producing this info.
Getting ready for new gears 22 392 jeep on 37s. After watching this, I am going with 5.13s. I really think it will compliment my hemi off the line. Run the exhuast open and someone is always trying to gap me.
I personally would give that another thought. A good friend of mine is a senior engineer at Jeep and he assures me that the 392 was made to run 38's with 4.56. I have personally tested this out and can confirm, that setup feels very much like stock. At most, I would go 4.88 for a bit more power. 5.13 will have you winding out.
@wayalife Yep, I just talked to the shop doing my gears. They also recommended 4.88s for my 392. Appreciate the advice and will use it. Love your channel, always solid content.
To be fair, that's just for the app. You still need to by an OBDII scan tool and adapter cable but yes, it's still a lot cheaper than some of the other options available out there and it does work well.
@@wayalife I have a JK so no cable needed. I also had a bluetooth dongle. The app is free. You just pay for the VIN perscription. Unfortanatly is does not work on my wifes Renegade (BU) yet. Some things you can do with a cable useing the Cherekee mode for things like tire size.
Paying for the VIN is what I meant and this video was made for a JL Wrangler or JT Gladiator and that's what I was referring to. But, I digress. Jscan is a good tool and that's why I featured it.
so with the 3.6 gas v6, 37s and 4.88 gearing with the auto trans what are people seeing for mileage figures after changing the programming? I also noticed he used an extender harness to connect his programming tool, where can those be purchased from?-BTW-this is on of the best Jeep channels on RUclips
MPG really depends on what type of 37 you're running. The more aggressive the tread as in, a mud terrain, the more rolling resistance you will have and that will reduce your fuel economy. The more street like the tread is, as in an All Terrain, the better it will be. I have personally tested this and have seen as much as a 2 MPG difference. The harness you see is this amzn.to/3hXiHqd and it is needed to connect this for a Jscan amzn.to/3PXcO97
I'm with you and I am installing new gears with a shop I know. I just talked to them yesterday. It's like you read my mind. I deleted my fad on my 2 door JL when I put in my new solid axle shafts. I have seen zero decrease in MPH. It was 18.5 MPH and it is still 18.5 MPH. I am running 4:10's on 35's on a turbo 2.0. I am curious how the mileage will dow after a 4:88 gear swap. Hmmm... I know right now my 8 gear auto is not solid in the 8 gear. It likes to stay in 7.
Clearly, to each their own. Having run both, I can say that 5.13 is nice but for daily driving and fuel economy, 4.88 has proven to be a better fit with 37's. Or at least, from what I have seen.
To each their own. From experience having done it both ways, I would tend to disagree. I am a guy who makes a living wheeling his Jeep and yet, I would be the first to admit that most of my time driving is on pavement and on the highway.
@@wayalife exactly. I only built 2 but I’d definitely have gone 5:13 on the jk /. 37’s if I had it over again wouldn’t have cost extra since I put an axle up front to replace the toothpick
Thanks so much for this video. Had no idea the time and complexity of doing a gear change. You really need to do your research to find a good shop that does this on a lot of jeeps. Oh.. and cool that you highlighted JSCAN at the end of the video. Awesome !! I'm going to be doing a series of videos on JSCAN. Oh.. how much total time did this take and how much did it cost for the labor and gears?
Another excellent video but I do have a question, I’m not to the point of needing gears but is there anything I can do to the 2.0 to help boost low end torque?
The advanteck is designed for the 75/85 and you get really good fuel economy with a tight tolerance gears. If curry is the only one who is mimicking that then that’s what I would buy only.
I'm running a 2020 JLUR with a 3.6L Auto, and just a few months ago I transitioned from 35" Falken Wildpeak A/T tires to 37" Falken Wildpeak R/T tires. About a month later I had my Jeep regeared with Revolution 4.88's, and after doing the 500 mile break-in I had the differential fluid replaced. All was good for about the next month, but then the Locker idiot light illuminated on my dash. Since then, my Locker idiot light is constantly illuminated and my lockers will not engage. No offroading or locker engagement was done during that initial month after the regear, but once that Locker idiot illuminated I did try to engage my lockers and they would not engage. Be aware that after the regear and before the Locker idiot light illuminated, I was simply daily driving my Jeep on city and highway roads (aka. no offloading). Has anyone else run into my "lockers won't engage" problem after their regear? ...Next week I have an app't with the 4x4 Shop that did my regear. Any ideas on what they might find to be causing my lockers to not be able to be engaged?
Could be something as dumb as a wiring problem. Maybe the plug wasn't plugged in all the way on the inside. I would definitely have the shop take care of it as it would be an issue that they created.
Nice video. Interested in when you think axle shafts are necessary. I was thinking about RCV's and chromoly axles. Hate to do it, but the time to do it is with gears... What do manufacturers do that you can drive it off the lot without any worries? I think all I saw in a Ford manual was no towing for 600 miles.
Me personally, the time to do it is when you actually need it. I've always found factory shafts to hold up well. Also, having run RCV on several Jeeps, I can tell you that you'd be better off running standard chromoly shafts with full circle clips. They're $400 more affordable and won't pop and snap loudly on the trail after hard use the way RCV will. Oh, and RCV will tell you that the noise is totally normal and they will not warranty it.
@wayalife after having some time now with 4:88, how is the power off the line compared to 5:13? How much are you giving up there vs. having lower rpm at highway speed? Would you still stay with 4:88 on a gladiator with 37s for a daily driver? Thanks for the great videos!
I don't think I'm giving up anything. If anything, it's noticeably faster off the line than when I was running the factory 4.10s. I really hated running 2500-2800 rpm on the highway with 5.13 especially when trying to pass on a 2 lane highway. At that rpm, the transmission WILL NOT drop a gear to get more power to pass as that would cause the engine to redline. With 4.88, the trans will still drop a gear and get me going faster. Of course, this is to say nothing about the improved mpg.
I want to know if utilizing a tazer or any other programming device to change the gear ratio is a suitable and sufficient option, or I should replace the gear instead ?
A Tazer or other programmer will allow you to enter in the correct tire size and gears you're running and that will ONLY correct your speedometer reading and make your transmission shift points correct. It will NOT restore power that you lost with the installation of bigger tires. New gears with the proper ratio is what you need for that AND a programmer will also be needed to set your computer.
I run 4.88's on my JKU with 35's, with the six speed manual. There is no way I would have spent the money to go from a 4.10 to a 4.56, it's just not enough to justify over $2000. Maybe if you never plan on hitting the dirt. I drive 50 miles a day, mostly highway and it does great. 35" tires with the 4:1 transfer case, 4.88's, and manual is just awesome in the rocks.
Eddie…I’m running a 2012 JKU set up very similar to Moby….in fact I think the only difference is mine is black 😂😂😂 so i’m curious to know after Moby’s L86/10L90 swap are you sticking with the 5.38’s or will you change to a 5.13 or 4.88 due to the 10L90? I am running an Atlas II (4.3:1) as well….just wanted to ask your opinion on gearing since our drivetrains are very similar
LOL - very cool. What I can tell you is that Moby is still running 5.38 and it's great for crawling and getting up off the line but overall, a taller gear would make him feel a lot faster, especially for daily driving. 4.88 might be a better fit but I really haven't felt a need to make the change.
@@wayalife Thankyou for your reply Eddie.....I talked with Kalan and he suggested 4.88's so we'll see how those work with 10L90 and 40's....appreciate you my friend 👊🏽
Happy to hear you enjoyed the video and what you're seeing is our Gladiator sitting on an EVO 4.5" lift. I specify brand only because no two lifts seem to measure the same or at least, from what I have seen.
@@wayalife thnx for the info as always. Few more questions if you don’t mind sir. Did you do the geometry correction bracket as you did on your other Gladiator being that you hit a 4.5” lift kit on?? And if you can tell me how much$$$ is the 4.88 Currier re-gearing kit plus install cost?? Disciple off-road. I’m on the east coast but I just want to know for sake of comparison. 🙏🏾
@@jerrykarpoleh204 This is the same Jeep that we featured on our geometry correction bracket video and yes, we installed them because of the lift height. Disciple charges $1,820.00 labor for a full regear with master install kits. Also includes a 500 mile inspection and oil change.
@@wayalife oh aiight n $1,820 is not bad at all. I got a price quote for my 2016 JK Rubicon for $3k? Is that reasonable?? 4.88-5.13 gear. Do know of any shops on the east coast that you could recommend for good service and great price??
@@wayalife yeah thanks man. And thanks to your prior video I got the Clayton rear track bar to fit the spare and didnt have to discover after job was done that it wouldn’t fit. Lol. Can’t wait to get it back tomorrow. Assateague Island beach driving in two weekends then hopefully my home trails of Wolf Den State Park in MD to get a feel for it and then somewhere in Tennessee over Thanksgiving. . Probably wont be Windrock bc gonna be in Chattanooga and don’t have time for the detour, but been watching some vids on Prentice Cooper State Forest just on other side of river from downtown so I am hoping to hit there a bit. Hope to get some footage for the channel. Look forward to seeing you get your baby out on the trails out there in the desert. Got any more mods planned at the moment?
I personally disagree. Based on personal experience running multiple JL Wranglers with 37's and even 38's and now this Gladiator running 37's, I have not seen a need for 1-tons on any of them. This is not to say that I don't run 1-tons on my big Gladiator running 42's or my JK running 40's and a 6.2L LT but then, that's a different story.
Question. I have seen you in the past use ECRI to adjust your tire sizes. But not using on this application. What was that extension cable you had attached to your OBD II READER? on the ECRI do I have to use the bypass module looks like the one you used was OBD II only not requiring plugging into bypass
Honestly, I personally wouldn't waste the money regearing for just 33's. I've run them with 3.45 gears and thought it was fine. With 3.73 or 4.10s, it's all you really need.
Would you do the same sort of gearing on a manual transmission? I have a 2018 Wrangler Rubi with a 2 inch lift and 35's. I feel like 6th is useless and I loss some power after 4th into 5th.
Hard to say. Assuming your Rubicon came with 4.10 gears, the cost to upgrade to 4.56 is pretty high for just a bit more performance. However, if you're okay with losing fuel economy, bumping up to 4.88 will give you a lot more power.
this video showed me everything i needed to know that i'm not doing this myself.
LOL - glad we could share it with you and yes, for how much it costs and how much things can be done wrong, this really is something best left to people who do it all the time.
They took way too much stuff off to be in the realm of what I’m comfortable doing lol

LOL - yes! And that's why it's a costly upgrade.
Re-gearing is one thing I dont not trust myself doing. I’m happy to pay someone else to do it properly.
Yup, that's why I had them do mine :)
I used the Rear End Shop in Livermore. Barry has been in the business for a long time and has a great reputation. 🇺🇸
Glad to hear there are other reputable shops in the area 👍

A lot of people just want a simple chart on what gears with a certain size tire, but there are so many variables to consider when picking gear ratios in addition to tire size. Things like tire weight, weight of vehicle, towing, engine, transmission, vehicle use, etc. should be factored when picking a ratio.

My JK is getting re-geared on Monday. Thanks for this video! I was curious to see the process.
Congrats to you and glad we were able to share this with you.
Love this video. I'm jumping to 37's soon and 4.88's BTH, love my toaster sticker and ya'll throwing in a Way of Life too sticker too!!
Awesome and glad you enjoyed the video 😎
Another great and informative how-to video.
Happy to hear you found it to be informative 😎
Great video!!! Welcome back, it’s been a while!!! 😀
We apologize for being gone a bit. Glad you enjoyed the video.
thx alote for all this precious info :P have a great day all
Glad to hear you found our video to be helpful 😎
Nice video. Definitely not a DIY job. Good to see you back Eddie.
Glad you enjoyed the video and while it can be a DIY job, it's not something I prefer to do.
Awesome info. Looks like great shop!
Glad you enjoyed the video and yes, if you live in the area or are willing to make the drive, Disciple is who I would recommend.
@@xmonger thank you sir 🙏🏼
Please open a shop here in Jacksonville, FL...... 🙂 🙂 It's so hard to trust someone to do this correctly!
Nice work by those guys! Good attention to detail, and knowing their job! I had my TJ re-geared years ago by a shop here in silicon valley and they really screwed up the installation of new gears and an ARB. I took it to another local shop who did what they could to straighten out the sloppy work. But its never been totally right since. The rear end is now making slight noises.... I may end up taking my TJ to Hanford this winter to have the rear end re-done. Thanks for the video!
Let me guess, the shop in question forgot or didn't know to cut drain slots on the axle tubes and you fried your bearings. Either way, Disciple should be able to help you out.
@@wayalife Bingo! lol
LOL - ask me how I know
40,s and 5:13 Revolution gears work Great on My 23 Willys Gladiator 🇺🇸💪✌️
Thank you for the insight. I have a 2018 Wangler Rubicon with a 3.6. I have 35's on my Jeep. I will be towing occasionally, so I think 488 will be good for me. Thanks!
Being that you are wanting to tow with your Jeep, I think 4.88 would be the right choice.
Great informative video!
Glad to hear you found our video to be informative.
I have a friend who has a 2023 Mojave with 38's (Nitto Ridge Grapplers) and stock 4.10 gears. he drives it pretty "chill" and takes it offroad, but still gets 8th gear on flat roads, but mostly useless. Truck seems to drive really well as is, but has Banks Pedal Monster which doesnt give more power, but throttle response is 1000% better.
Thanks!
Disciple added a rear stabilizer and adjustable shocks for my Eco diesel Gladiator before I headed to Alaska. Thanks for recommending them.
Thank you so much for that!! We really do appreciate it 😊
Awesome! Hope you had a great trip 👍
Hanford?! I used to live there. I never knew you were close to there. Great vid as always
Actually, we're not that close. We live in Carson City, NV but are always happy to make the drive out to see our friends 😎
@@wayalife oh that’s makes sense.
a 3.8 with 4.10s and an automatic meaning 4 gears can also push 37s
I cant believe the 3.6 with eight gears still isnt doing any better 😒
Good video, I really like the content ya got I learn so much👌
There's a big difference between being able to do something and doing it well.
For those of you wondering why the pinion gear has to get smaller as the gear ratio gets bigger 3:73 to say a 5:13 is because the housing is only so big. If the housing could fit a bigger ring gear, the pinion wouldn’t need to be smaller, but since the housing is only so big, the pinion is what gets smaller.
Thank you
Glad we could share this with you.
Nice video. I like that tray that you guys were using to put the carrier and shims in. Where did you guys find that?
It's a rubber tool pad that we got at Harbor Freight
Fantastic video! 👏
Thank you very much!
@@wayalife I do have one question. Apologies if it's a complicated question. I'm basically in a very similar scenario to the JT you just had re-geared, 4.5" lift and 37s. I've been debating what gear ratio to install. I have steel bumpers front and back, winch, armored side steps, a heavy steel bed rack... But more importantly I also live and operate my JT at pretty high altitude: 7,500+ ft. Is this a case for a bit of a higher gear ratio than the 4:88? I'm not going to be doing a lot of interstate driving. A lot of mountain passes, camping, maybe towing an occasional pop up camper, etc. I'd be curious what your thoughts were? Thanks!
The extra weight you have wouldn't get me to want a higher ratio and while I'm not at the same altitude as you, I do live at 4500 and the mountains I live next to and travel across on a somewhat regular basis gets up close to 8000. None of this is a problem for me with 4.88. That said, if you do plan on towing, the extra power that 5.13s provide would be worth having.
@@wayalife Thank you! Your real world experience is valuable. It's a big investment that I don't want to have to redo... So all information I can gather to make an informed decision is a plus. Really appreciate it!! 🙌
Fascinating - Excellent and informative video, love this. I have so much back lash in the drive line of my brand new Gladiator, wonder if the diffs aren’t set well from factory.
Is it safe to assume you have a manual? I so, could just be drive train clash. Your gears shouldn't have so much in the axle from the factory.
Long way from Nv. Eddie! Haha. Have never been to Disciple Off Road, but they used to be close when I was in Fresno... now in Idaho and that's just a bit too far! Lol. Thanks for the video. 👍
Glad you enjoyed the video 😎
Great informative video and I really like the credibility of Disciple off road! 🔥 Still wondering what happened to Jet? Was he a trade in for the 392?
Unfortunately, we did sell JET to make room for our 392. Glad you enjoyed the video.
@@wayalife awwww dang Jet was my favorite besides Moby we were building my parents 2018 Jeep JLUR simultaneously to Jet but I do love the 392 and the new JT
Trust me, selling JET wasn't easy but we just don't have room for them all and a 392 isn't cheap.
Agreed! My 2019 JLUR on 37's never went into 8th gear. Switched to 5:13's & has great acceleration & goes into 8th gear easily. I was worried that 5:13's would be too steep, but cruises great on the highway at about 2600 RPM at 75 MPH
Yup, sounds about right to me and the power is fun to have. That said, 2600 rpm at 75 mph is way higher than what I'd prefer to have this Gladiator running at. Of course, that's just me.
2600 is a tad bit too much bud! 75 might be the speed limit in areas you live, but you need to really keep it close to 2300 for gear change and cruise at about 1900,2100. These trucks really hold onto gears on ascends so when going up just keep your foot as still as you can and it’ll stay in gear and get you over the hill. In long ascends I’m in 6th at about 2200 and I ease back into 7th once we’re over the top.
I just want to add, for my older 2007, with the 3 speed/OD and 3.8, the Rubicon 4 door with stock 32s struggled on the freeway. Once I updated to 35x12.50's it was terrible. I upgraded to 5.13s and it was perfect, better than stock by a few hundred rpms. Absolutely Perfect for the original JKs, I put at least 80K on those gears no issues. I sold that in 22 after I bought my 21 4XE.
I find it interesting with my 21 4XE Sahara with 35's (ARB Air locker, lifted, build out, etc.) and feel zero need to upgrade. The 2.0 has so much torque+Electric I don't even notice the difference. And my fuel, around town with 70 mile trip a week is at 35 MPG, my old 07, I was lucky to get 12 mpg. Oh and for me in AZ, Desert Rat has done all my gearing for the JK and locker for the 4xe. Perfect jobs, no issues.
As I state in the video, the all new 8-speed automatic transmission is totally up to the job of pushing bigger tires and at just 35", I wouldn't bother regearing.
@@wayalife Ya, love your videos! Good info. as always!
Thanks, great video! Very informative.............
Glad you enjoyed it!
@@wayalife the more I've thought about this video the more I realize just how educational and helpful this video is. Much gratitude for your time, work and skill at producing this info.
@@maxvanrunkle1052 Really happy to hear it ang glad we could share it with you.
Getting ready for new gears 22 392 jeep on 37s. After watching this, I am going with 5.13s. I really think it will compliment my hemi off the line. Run the exhuast open and someone is always trying to gap me.
I personally would give that another thought. A good friend of mine is a senior engineer at Jeep and he assures me that the 392 was made to run 38's with 4.56. I have personally tested this out and can confirm, that setup feels very much like stock. At most, I would go 4.88 for a bit more power. 5.13 will have you winding out.
@wayalife Yep, I just talked to the shop doing my gears. They also recommended 4.88s for my 392. Appreciate the advice and will use it. Love your channel, always solid content.
Awesome Outstanding job thanks
Thank you :)
Your videos bar none are the best! Convinced me to have a pro do my 4.88 u/g (37’s on 21’ 2DR Rubi 3.6). Any shop recommend for the Phoenix AZ area?
Truly humbled that you would say as much. Unfortunately, I am not aware of any shops that I could recommend in the Phoenix area. Sorry.
JScan is awesome!!!!! Well worth the $20.
To be fair, that's just for the app. You still need to by an OBDII scan tool and adapter cable but yes, it's still a lot cheaper than some of the other options available out there and it does work well.
@@wayalife I have a JK so no cable needed. I also had a bluetooth dongle. The app is free. You just pay for the VIN perscription. Unfortanatly is does not work on my wifes Renegade (BU) yet. Some things you can do with a cable useing the Cherekee mode for things like tire size.
Paying for the VIN is what I meant and this video was made for a JL Wrangler or JT Gladiator and that's what I was referring to. But, I digress. Jscan is a good tool and that's why I featured it.
so with the 3.6 gas v6, 37s and 4.88 gearing with the auto trans what are people seeing for mileage figures after changing the programming? I also noticed he used an extender harness to connect his programming tool, where can those be purchased from?-BTW-this is on of the best Jeep channels on RUclips
MPG really depends on what type of 37 you're running. The more aggressive the tread as in, a mud terrain, the more rolling resistance you will have and that will reduce your fuel economy. The more street like the tread is, as in an All Terrain, the better it will be. I have personally tested this and have seen as much as a 2 MPG difference. The harness you see is this amzn.to/3hXiHqd and it is needed to connect this for a Jscan amzn.to/3PXcO97
I'm with you and I am installing new gears with a shop I know. I just talked to them yesterday. It's like you read my mind. I deleted my fad on my 2 door JL when I put in my new solid axle shafts. I have seen zero decrease in MPH. It was 18.5 MPH and it is still 18.5 MPH. I am running 4:10's on 35's on a turbo 2.0. I am curious how the mileage will dow after a 4:88 gear swap. Hmmm... I know right now my 8 gear auto is not solid in the 8 gear. It likes to stay in 7.
Love my 5.13 on my Gladiator Rubicon with 37" tires. Glad I didn't go 4.88
Clearly, to each their own. Having run both, I can say that 5.13 is nice but for daily driving and fuel economy, 4.88 has proven to be a better fit with 37's. Or at least, from what I have seen.
Always go with the lower gear if you’re deciding between 2 gearings. When wheeling - be easy on the pedal
To each their own. From experience having done it both ways, I would tend to disagree. I am a guy who makes a living wheeling his Jeep and yet, I would be the first to admit that most of my time driving is on pavement and on the highway.
@@wayalife exactly. I only built 2 but I’d definitely have gone 5:13 on the jk /. 37’s if I had it over again wouldn’t have cost extra since I put an axle up front to replace the toothpick
Thanks so much for this video. Had no idea the time and complexity of doing a gear change. You really need to do your research to find a good shop that does this on a lot of jeeps. Oh.. and cool that you highlighted JSCAN at the end of the video. Awesome !! I'm going to be doing a series of videos on JSCAN. Oh.. how much total time did this take and how much did it cost for the labor and gears?
Every shop charges differently. Disciple charges $1820 and that includes everything. But, anything from around $2k-$4k sounds reasonable to me.
@@wayalife Thanks so much.
Great as always! $6.99 for gas!!! 😮😮😮
Tell me about it!! California!! 🙄
holy 💩! Loved the video but some things i wish i could unsee so I'm not afraid to attempt this on my own. Ignorance is bliss!
LOL - best of luck to you.
And now we know 😊 🇺🇸 👍
LOL - glad we could share this with you 😎
Another excellent video but I do have a question, I’m not to the point of needing gears but is there anything I can do to the 2.0 to help boost low end torque?
Unfortunately, not really. I don't know why Jeep got rid of etorque on the 2.0L because it was awesome.
When I got my jt regeared first 500 miles turned out to be the heat cycle period 😂
Nice vid, just wondering if you have tried the orange loctite
Glad you liked the video. Unfortunately, I have not tried orange.
The advanteck is designed for the 75/85 and you get really good fuel economy with a tight tolerance gears. If curry is the only one who is mimicking that then that’s what I would buy only.
From what I understand, Currie the only one or at least, for now.
I am running 4.88 in my jeep jk with 35x12.50r17 and I will definitely be going up on size cause my rpms at 60 mph are like 2500 to 2800
Yeah, those are really high RPM. 37's are definitely a better match for your gear ratio.
I'm running a 2020 JLUR with a 3.6L Auto, and just a few months ago I transitioned from 35" Falken Wildpeak A/T tires to 37" Falken Wildpeak R/T tires. About a month later I had my Jeep regeared with Revolution 4.88's, and after doing the 500 mile break-in I had the differential fluid replaced. All was good for about the next month, but then the Locker idiot light illuminated on my dash. Since then, my Locker idiot light is constantly illuminated and my lockers will not engage. No offroading or locker engagement was done during that initial month after the regear, but once that Locker idiot illuminated I did try to engage my lockers and they would not engage. Be aware that after the regear and before the Locker idiot light illuminated, I was simply daily driving my Jeep on city and highway roads (aka. no offloading). Has anyone else run into my "lockers won't engage" problem after their regear? ...Next week I have an app't with the 4x4 Shop that did my regear. Any ideas on what they might find to be causing my lockers to not be able to be engaged?
Could be something as dumb as a wiring problem. Maybe the plug wasn't plugged in all the way on the inside. I would definitely have the shop take care of it as it would be an issue that they created.
@@wayalife Apparently there is a design problem with the locker sensor in JL/JT Rubicons: ruclips.net/video/TYFrQkrWBE4/видео.html
@@gregrusteikas9578 yeah, that's why the locker you see in this video is different.
Nice video. Interested in when you think axle shafts are necessary. I was thinking about RCV's and chromoly axles. Hate to do it, but the time to do it is with gears...
What do manufacturers do that you can drive it off the lot without any worries? I think all I saw in a Ford manual was no towing for 600 miles.
Me personally, the time to do it is when you actually need it. I've always found factory shafts to hold up well. Also, having run RCV on several Jeeps, I can tell you that you'd be better off running standard chromoly shafts with full circle clips. They're $400 more affordable and won't pop and snap loudly on the trail after hard use the way RCV will. Oh, and RCV will tell you that the noise is totally normal and they will not warranty it.
What cover did yoy use for the differential? Look super nice
The cover is made by Currie, just like the gears.
@wayalife after having some time now with 4:88, how is the power off the line compared to 5:13? How much are you giving up there vs. having lower rpm at highway speed? Would you still stay with 4:88 on a gladiator with 37s for a daily driver?
Thanks for the great videos!
I don't think I'm giving up anything. If anything, it's noticeably faster off the line than when I was running the factory 4.10s. I really hated running 2500-2800 rpm on the highway with 5.13 especially when trying to pass on a 2 lane highway. At that rpm, the transmission WILL NOT drop a gear to get more power to pass as that would cause the engine to redline. With 4.88, the trans will still drop a gear and get me going faster. Of course, this is to say nothing about the improved mpg.
Awesome thanks for the feedback!
I want to know if utilizing a tazer or any other programming device to change the gear ratio is a suitable and sufficient option, or I should replace the gear instead ?
A Tazer or other programmer will allow you to enter in the correct tire size and gears you're running and that will ONLY correct your speedometer reading and make your transmission shift points correct. It will NOT restore power that you lost with the installation of bigger tires. New gears with the proper ratio is what you need for that AND a programmer will also be needed to set your computer.
I run 4.88's on my JKU with 35's, with the six speed manual. There is no way I would have spent the money to go from a 4.10 to a 4.56, it's just not enough to justify over $2000. Maybe if you never plan on hitting the dirt. I drive 50 miles a day, mostly highway and it does great. 35" tires with the 4:1 transfer case, 4.88's, and manual is just awesome in the rocks.
@@quintili1 we typically only suggest gears if we can make at least two jumps in ratios to make it worth while in performance and of course the price.
Being new to Jeep what is the rough damage to do this upgrade?
Every shop is different but at Disciple Off Road, you're looking at about $1800 for everything.
What’s the opinion on a Rubicon Gladiator EcoDiesel running 37s. I like to tow a trailer with the JK, but do more daily than towing….
4.56 is what I would go with.
A lot of workmanship and care during the install. Definitely not plug and play. Let the pros do it.
That's how I feel about it and as I mention in the video, this is something that I could do.
Eddie…I’m running a 2012 JKU set up very similar to Moby….in fact I think the only difference is mine is black 😂😂😂 so i’m curious to know after Moby’s L86/10L90 swap are you sticking with the 5.38’s or will you change to a 5.13 or 4.88 due to the 10L90? I am running an Atlas II (4.3:1) as well….just wanted to ask your opinion on gearing since our drivetrains are very similar
LOL - very cool. What I can tell you is that Moby is still running 5.38 and it's great for crawling and getting up off the line but overall, a taller gear would make him feel a lot faster, especially for daily driving. 4.88 might be a better fit but I really haven't felt a need to make the change.
@@wayalife Thankyou for your reply Eddie.....I talked with Kalan and he suggested 4.88's so we'll see how those work with 10L90 and 40's....appreciate you my friend 👊🏽
As alway great informational vid. How much lift (inches) do you have on the rig. I like the stance with the 37’s
Happy to hear you enjoyed the video and what you're seeing is our Gladiator sitting on an EVO 4.5" lift. I specify brand only because no two lifts seem to measure the same or at least, from what I have seen.
@@wayalife thnx for the info as always. Few more questions if you don’t mind sir. Did you do the geometry correction bracket as you did on your other Gladiator being that you hit a 4.5” lift kit on?? And if you can tell me how much$$$ is the 4.88 Currier re-gearing kit plus install cost?? Disciple off-road. I’m on the east coast but I just want to know for sake of comparison. 🙏🏾
@@jerrykarpoleh204 This is the same Jeep that we featured on our geometry correction bracket video and yes, we installed them because of the lift height. Disciple charges $1,820.00 labor for a full regear with master install kits. Also includes a 500 mile inspection and oil change.
@@wayalife oh aiight n $1,820 is not bad at all. I got a price quote for my 2016 JK Rubicon for $3k? Is that reasonable?? 4.88-5.13 gear. Do know of any shops on the east coast that you could recommend for good service and great price??
How timely. My JTR is in the shop right now getting 37s and a regear to 5.13s. Doing the Clayton rear trackbar also.
Glad we could share this with you.
@@wayalife yeah thanks man. And thanks to your prior video I got the Clayton rear track bar to fit the spare and didnt have to discover after job was done that it wouldn’t fit. Lol. Can’t wait to get it back tomorrow. Assateague Island beach driving in two weekends then hopefully my home trails of Wolf Den State Park in MD to get a feel for it and then somewhere in Tennessee over Thanksgiving. . Probably wont be Windrock bc gonna be in Chattanooga and don’t have time for the detour, but been watching some vids on Prentice Cooper State Forest just on other side of river from downtown so I am hoping to hit there a bit. Hope to get some footage for the channel. Look forward to seeing you get your baby out on the trails out there in the desert. Got any more mods planned at the moment?
Hello! What are the devices' used on this video to connect to the Jeep? Links?
Here's a link to what I used amzn.to/3PXcO97 and you will need this as well amzn.to/3hXiHqd
With them, you just need to download Jscan on your phone.
If you’re regearing for anything bigger than 35’s you should really consider 1 ton axles or your looking at broken axles.
I personally disagree. Based on personal experience running multiple JL Wranglers with 37's and even 38's and now this Gladiator running 37's, I have not seen a need for 1-tons on any of them. This is not to say that I don't run 1-tons on my big Gladiator running 42's or my JK running 40's and a 6.2L LT but then, that's a different story.
Do they make 300m ring and pinion gears and are they better then chromoly gears?
Question. I have seen you in the past use ECRI to adjust your tire sizes. But not using on this application. What was that extension cable you had attached to your OBD II READER? on the ECRI do I have to use the bypass module looks like the one you used was OBD II only not requiring plugging into bypass
The cable is just an adapter that is needed to hook up the diagnostic tool for Jscan.
What about 33s on a Sport wrangler?
Honestly, I personally wouldn't waste the money regearing for just 33's. I've run them with 3.45 gears and thought it was fine. With 3.73 or 4.10s, it's all you really need.
Maybe I missed it, did you change the front gears as well?
You missed it. See video from here ruclips.net/video/bNlCEE3Xwj4/видео.html
13.9 MPG. Did that go up or down? 😊
LOL - good eye and considering most of our drive was going up and over the Sierra Nevada Mountains the long way, it was up 😎
Would you do the same sort of gearing on a manual transmission? I have a 2018 Wrangler Rubi with a 2 inch lift and 35's. I feel like 6th is useless and I loss some power after 4th into 5th.
Hard to say. Assuming your Rubicon came with 4.10 gears, the cost to upgrade to 4.56 is pretty high for just a bit more performance. However, if you're okay with losing fuel economy, bumping up to 4.88 will give you a lot more power.
Is that Jpass software app from factory app or is it after market?
The Jscan software is not made by Jeep.
I wonder if you only had 35's with a 4/10 would you notice a big difference ?
Not between 4.10 and 4.56. For me, I wouldn't make the upgrade.
What brand of gears are you using?
As I state in the video, we went with Currie.
