The fuel line, is callled a "bump stop" it stops the bottom out effect where the rolling energy is increased by the bottoming out. You are basically adding an integrated bump stop, something that most decent coil over manufacturers on real cars do.
Most off-road shocks (King, Fox, Sway-away etc.), do not have an internal bump-stop. Since they don’t they rely on a separate bump stop and/or limit straps.
I just bought 2 Slash RWD cars for my daughter and I to start racing locally and since the class does not allow for any part upgrades, the shop said focus on tuning shocks. I bought heavier oil, but the half rebound seems like an incredible upgrade especially since these things just have insane amounts of body roll out of the box. I just rebuilt her Rustler (4x4) shocks, and I wish I would have found this video first. I might go back and set her shocks up like this. My E-Revo 2.0 VXL is the next on the list for some shock rebuild love.
Nicholas John i bet the guys in your area are already doing this and not telling anyone. Originally this class was designed to be cheap. Its still cheap with fuel line in your shocks ;)
Did this to my 2wd rustler but I used the extra shock pistons and it worked perfectly. Also put the rpm 4x4 rear carriers on my rusty and they take a beating compared to the stockers
It’s called less droop and it allows more weight to be transferred to the front or rear of the car. Got my information from XXX Main Chassis Setup Guide.
roddas26 Na, Sag is how much drop in travel there is when the static weight of the car/person’s weight is on the chassis. The original comment is closer to what this mod is. Essentially limiting the overall travel of the shock.
Cool upgrade.. I appreciate what you are doing for your sons. I did the same thing only I started then on Tamiya kits the way I did and that way they built the whole car. I got them their first nitro in 08 which was the Tmaxx and they were able to strip the car and rebuild without looking at the manual. I wanted them to understand the concept on an engineering standpoint before they got RTR that was race ready. I wish Traxxas had a kit but in today’s world where everyone’s busy they don’t have the time nor patience to truly learn the way I did in 1983 when I started. I’m my opinion if you want to teach your children mechanical inclinations then get them a Tamiya or Kyosho and when they are ready to race at that level then get them a Traxxas. Great video thanks for the tip!
Thanks for that. I have been wondering which oil weights I should be using when I rebuild my shocks. What do you use in the rear? If you dont mind me asking!!
I know this video has been out a while but yes this helped out a ton now I can't even hardly get my slash to roll over. Thanks for the tip. And if people want to know I used 1/4 inch fuel line on each shock with 50w oil.
Personally, i have a 4x4 slash and i have never ever broke one of those and i have had mine for like 5 or so years. The gearbox tho, thats a different story
Lockdown spinning my setup is for both , I use a lcg chassis and in the shock i use one or two rod ends ball in the shocks . I drag race so it will bring your arm straight and make the car more stable.
I was turned on to another cheap as nearly free upgrade to the 2wd Traxxas cars. Drill out the hole for the king pin in the caster block and steering knuckle to 1/8", use the rear axle pin as the new king pin. Haven't tried it myself yet, but sounds like it has some real potential. Aluminum caster blocks/steering knuckles are a worthwhile investment IMO, but not everyone wants to drop the cash on that. I'll have to give it a shot for testing purposes.
The part I used to always break, is the drive shafts especially when I go 3s , and that’s mainly on the stampede 4x4 Vxl, but not any more I have steel mip cvds installed front and back
Awesome video, I've been playing around in this hobby for over 30 years and you not only helped my two wheel drive cars out, not just my Traxxas cars but I have been needing to figure out how to limit the travel of the rear shock for all of my RC motorcycles that I want to put piggyback car shocks in place of the stock motorcycle rear suspension. Thank you very much for making this video.
Thanks for taking the time to make this video. I just got my 1st traxxas, rustler 2wd. Took it out for it's 1st test drive yesterday & noticed what you mentioned, easy to rollover when driving on the pavement. On the grass it performed excellent, no rollovers. But I prefer to ride on pavement, faster speeds & less clean up lol. Now, my traxxas came with this whole shock tuning kit. I believe that it has these little tube spacers that do that same function as the fuel line that you used. Unfortunately traxxas doesn't give you any additional information on what all these parts are & how to use them. But I definitely want to make this modification to the shocks. And thanks for the rebound tip, I wasn't aware of that. 👍 Update : So, I used those spacers inside the shocks, WOW!!! What a difference!!! Car stays flat on the ground & does 180° turns on the spot @ high speeds!! This mod lowered the height & stiffened the suspension. I was able reused the same stock oil, specially since the car is new. I believe traxxas uses 30W stock. Thanks a bunch, this mod made this car much more fun now. Still rides nice on grass too. Win win!! 👍
When you first fill up the shock with oil it's said to be better to fill it half way so the bubbles get out more sufficient, and on the second time you fill it you do fill it all the way up..
For off-road on my 2wd vxl slash, I made the shocks more vertical, added some pre compression on the front and rear, sealed diff with diff fluid (but it seems to be not effective as fluid comes out of the casing super easily), lcg chassis, badlands tires, and it handles great on bumpy grass fields.
Yeah, that is a great mod, done to both mine and my son's Slashes, he gets the biggest benefit from this mod, as he doesn't modulate his throttle very well, and now doesn't roll nearly as much.
I was surprised when you revealed what breaks most often. As a 4x4 Slash owner, I was curious since I've been bashing mine for years. But I was surprised because those carriers have never been a problem on mine but mine came as a Platinum edition, meaning all four corners have Traxxas aluminum parts. Just figured I'd mention this if you don't mind laying out the coin, and want to fix it for good.
I have owned a Slash, Bandit, and I'm currently souping up my second Stampede. Not once have I broken a rear hub carrier. I have broken front steering and suspension components multiple times on each, however.
I’ve done this to my Erevo V1 I make my shocks like yours. Me running on street and dirt no jumps. With the weight of the erevo what shock spring/oil would you recommend?
the part about adjusting the rebound , something new to me and I think it could be very helpful I've been putting my shocks back together fully extended great tip thank you
So insane how similar to real racing this upgrade is !!! I do this same thing in my full size race car during practice to set up my car to specific tracks we call it Bump Stop !!! I have all different size pieces of rubber with also different compression rates of the rubber like softer or harder pieces in different sizes also ... I'm new to RC's and since ii finally have a son I'm just now getting into the hobby with my little man ! It's all the same concepts just on different scales ! Love it man great info . Knowledge is power sir 👍
I don't have any off road cars, I have the Losi 22s Summit Drag Camaro, and the Traxxas Drag Slash I got into R/C racing very recently because of the drag cars. But I have subbed to your channel because, of the enormous amount of information in your videos. I've heard of that shock trick before in one of the drag race videos, but I didn't know what it meant to have fuel line in your shocks. I knew there was oil in my shocks, but fuel line?? Well now I know what they meant, and how to do the upgrade. Thanks from a newbie to the R/C hobby.
My rear bearing carrier on my 2WD Rustler broke just the other day and this just so happens to show up in my recommended! I ended up replacing all 4 bearing carriers with aluminum parts from Atomik, so far so good!
Great channel ! My son Nate is a nut about Traxxas RC’s. He’s 9. I’m lucky to be his mechanic and enjoy doing it. He has a several different RC CARS, DRONES and others. Currently he’s running a Traxxas Rustler VXL 3500 brushless truck. My question to you is. Do you have any advice on much needed upgrades for best enjoyment? Your suggestion on tool manufacturers, tool set must haves? Most common part replacement? Parts to always have on hand? Best online store to order from? And lastly Your opinion/review on best choice RC for him Nate is also deaf, Autistic and ADHD. SO HIS SENSORIES are very elevated and his excitement is big time. He loves trying to jump it and burnouts. Oh yeah and of course speed! Hope you and yours have a very Merry Christmas
So you take away the ability to take turns at higher speeds so you have to deal with a gimped system as a learning tool. So what, you learn how to drive worse? Sorry but this sounds ass backwards to me. Surely not a race winning strategy.
@@zedorda1337 actually, softer suspension (= body roll) can be faster. It's just not faster if you flip over. If you had no suspension at all, the car would be almost impossible to flip but it would also have less grip so when you entered a corner too quickly you'd just start sliding.
For those wondering, as o-rings have been mentioned- in the harbor freight oring multi-pack you’ll want the smallest o-ring A005 it’s 3/32”x15/64”x9/128” this will give a snug fit!
Interesting... I'll definitely have to play with this mod. After upgrading the unassembled slash kit to VXL and running 3S that body roll really shows itself. With a bit less travel on the shocks, maybe I can keep 4 wheels on the ground more often :)
Nice. Need to do that on 4x4 Rustler as well. I have it jacked up for all ways possible for clearance, and mad tight suspension for supercross jumps but now it just flips out at even the sight of a corner coming LOL.
Gotta have the droop though to properly use the physics of the suspension on jumps. The more throw a shock has, the more cusion it can provide on landing. Just thicken the oil on the car. It's way too light out of the box anyway. Then if that doesn't work you can get a sway bar kit for it or fashion one out of piano wire!😁
good tip. I think you actually mean it will "limit how far the shock will compress" not decompress. Compression is when the shock is under load, decompressed is when it is unloaded.
No actually he meant decompress. decompressed, the shock is shorter due to the fact that the piston cannot travel all the way to the bottom of the cylinder because of the hose on the shaft just below the valve. for it to work on the compression, the hose somehow would have to be put on the top of the shaft above the valve...but that does not make the shot shorter and does not help the problem of to much decompression on the inside wheel in a turn.
I have a slash 4x4 also, running the 4 pole valeneon motor and esc on 3s with big tires but I cant even drive but for maybe 10 minutes at the most before it over heats. Pretty sure the pinion gear is too big being as it's an 18/50. Just ordered a 12-16 tooth pinion gear set, hoping that will work. I literally FOUND a slash 4x4 and a ruckus ecx 2x4 along with two 3s lipo batteries, 2 nmhi batteries a spare set of tires and a bag full of replacement parts and pieces including a brand new spare valeneon motor and esc combo and a metal roll cage for the slash and 2 transmitters, IN THE DUMPSTER!!!! even found a nmh battery charger with it all also lol only money I have in all of it is some xt90 connectors, and a different TQI transmitter and a charger for the lipos.. I literally accidentally found a new hobby haha
Hey, your videos are very helpful, can you show a current monster slash 2wd build, all videos outdated, tires discontinued? My sons and I are learning from ya!!! Thanks. CJ
Thanks Mark, how did you come up with this solution? Just inerested in the story, i've heard of people putting the fuel line on the outside of the shock like a limiter, i think the stock 2wd has them on the rear shocks. Is this a different scenerio that im talking about?
So the brakes cleaner will make the plastic look like new without the oil to attract dirt? And should you stay away from spraying it on anything specific..thanks and please respond
But they are not made of ABS and won't be changed in anyway with boiling. That is an extremely old and obsolete trick. Because now they are made from fiber reinforced nylons.
I know there are so many SCTs out there but can a traxxas 4x4 race against the big dogs on a track and what must modification should be done to keep up/or beat them?
Hi, Try soaking the rear hub in WD40 for a couple of hours to make it more flexible. As for the fuel line, I would not recommend it for a spacer for inside the shock, it will break apart from bing under pressure all the time. I would recommend either a proper plastic internal shock limiter or silicone shock O-Rings.
They have the blue frame that’s about $30 that make the handling better as well and these 2 together and be amazing. Also that antenna can be shorten to stay under the body and not stick out.
Hey Mark, great vid and tutorial. I get that same "dork" look from my wife too. lol. unrelated question: I have a traxxas slash 4x4 from 2015 and the tires are wearing out. I mainly run on the street and a some dirt. id like to go badlands, but I'm thinking a wiser choice that maybe I just go with bfg mud terrain km2, or the kr2. I don't want to have to lift it, as im running stock shocks. thanks for advice on what preglued tire/wheel combo u think I should go with. thanks
Hey man, this is so awesome. I'm getting this setup on my kids cars soon and thanks for the shock tutorial too. I actually used to help Traxxas with their engineering systems in Waco but never learned to properly work on my own lol. Quick question, one of my sons has a Rustler XL-5 and wants it to be more bash friendly. He saw some of those ProLine Badlands MX28 tires on a VXL and they looked awesome. But I've been told that the XL-5 would likely struggle to push that big of a tire. He's stolen his brothers Stampede Talon tires and that size seems to work (about 4.6in diameter and 2.6in wide). But it seems like no one likes the Talons. Is there another tire you'd recommend for us? I'm fine with regearing it and we aren't racing. Thanks bro!
Hey Mark good video like always. But I wonder if you could help me. I have a 2x4 slash 25 turn motor. I than upgraded it to a monster slash with 2.8 tires vxl motor and 3s batteries. Now I have gone thru 2 tranny housings 4 clutch kits. When I install everything new after 2 minutes after driving the clutch is rally hot and will melt the tranny housing. I have the slipper clutch set to 1/4 turn out so it don’t slip. Still gets so hot that I can not drive the Rc. What am I doing wrong
No, adding more shock collars would add more compression and would exacerbate the roll-over problem he's trying to correct. He's basically lowering the car for cheap with this mod.
So what happens if you combine the roll bars with the fuel tube trick? I ordered the wrong sway bar set, I need the larger ones for my VXL 2WD. This is my first RC truck and I converted it to a monster slash because the property terrain is really rugged here at the house. I think the shock setup is not right yet so I hope this helps the handling out. Sounds like it will since youv'e tested it over and over. Got lots of fuel line for my boats. Question I have is this: Does the shock fluid eat the fuel line over time?
The fuel line, is callled a "bump stop" it stops the bottom out effect where the rolling energy is increased by the bottoming out. You are basically adding an integrated bump stop, something that most decent coil over manufacturers on real cars do.
Most off-road shocks (King, Fox, Sway-away etc.), do not have an internal bump-stop. Since they don’t they rely on a separate bump stop and/or limit straps.
I get your point though.
Nice tip! if anyone has a hard time cutting fuel line even/equal JConcepts 2295 limiters work great as well
Justin with the better idea thank you sir.
Wow, just wanted to say thank you so so much. It has totally changed how it was handling. Now my friends wanna know how I did it.
I just tried this shock adjustment and setup. Wow thanks a ton this really helped.
I do oval racing and it helped alot

"my wife gave me that you're a dork look" - I LOL'ed. I identify with this! I had to subscribe, bro!
Omg he said it and immediately pictured my wifes your a dork face 🤣😂 same here at the same moment ii hit subscribe
Great tip I will have to this mine as I was told to buy the 4x4 chassis to stop the roll over as I have experienced at my local track. Thanks mate.
I've only ever broken front bearing carrier and caster blocks and instantly upgraded to rpm best investment lol
Did this to my 2wd rustler but I used the extra shock pistons and it worked perfectly. Also put the rpm 4x4 rear carriers on my rusty and they take a beating compared to the stockers
It’s called less droop and it allows more weight to be transferred to the front or rear of the car. Got my information from XXX Main Chassis Setup Guide.
We call it sag in the mtb world.

@@cencoast_7.340, I wasn't correcting the OP just saying that with Mountain Bike suspension it's called sag. Which it is. Cheers

60-70 weight oil works for my SCT’s in the front. Without losing wheel travel.
Thanks for that. I have been wondering which oil weights I should be using when I rebuild my shocks. What do you use in the rear? If you dont mind me asking!!

Personally, i have a 4x4 slash and i have never ever broke one of those and i have had mine for like 5 or so years. The gearbox tho, thats a different story
My 9 year old son and I just started racing spec slash here in Indy this year (January 2019). Thanks for the setup tip!
Landon Chapman we are based in Ohio and our first rc race car will be the slash
I use the rod end ball for my shocks . Fuel line still have give . The ball from the rod end take out the guess work. But thats a great tuning trick.
Lockdown spinning my setup is for both , I use a lcg chassis and in the shock i use one or two rod ends ball in the shocks . I drag race so it will bring your arm straight and make the car more stable.
Do the ball ends add more weight vs the thin tube?
I was turned on to another cheap as nearly free upgrade to the 2wd Traxxas cars.
Drill out the hole for the king pin in the caster block and steering knuckle to 1/8", use the rear axle pin as the new king pin.
Haven't tried it myself yet, but sounds like it has some real potential. Aluminum caster blocks/steering knuckles are a worthwhile investment IMO, but not everyone wants to drop the cash on that. I'll have to give it a shot for testing purposes.
1:50 and 3:10 - You're welcome.
I use small o rings so it’s more precise!

What motor and batteries do you suggest for a decent upgrade for this sct?
The rear bearing carrier might only be a problem on the slash because I do 40-50 foot jumps with my 2wd stampede and have never broken one
its the same part
I normally take sway bars off. I like a bit of roll makes you learn to take the corners slower and accelerate smoothly.
So you take away the ability to take turns at higher speeds so you have to deal with a gimped system as a learning tool. So what, you learn how to drive worse? Sorry but this sounds ass backwards to me. Surely not a race winning strategy.

Glad I got the platinum that comes with aluminum turnbuckles and sway bars stock
Thanks for the shock teardown
Simple cheap upgrade. Was gonna buy better shocks now I dont have too. Thicker oil very little rebound works awsome. Thanks
Yeah, I am all too familiar with that looml. It is my wife's default facial expression.
Interesting... I'll definitely have to play with this mod. After upgrading the unassembled slash kit to VXL and running 3S that body roll really shows itself. With a bit less travel on the shocks, maybe I can keep 4 wheels on the ground more often :)

Thanks Mark! I bought my first Slash VXL a few days ago and was trying to figure out how to get the sponge out of it.
Mark you seem like a good dude. Very easy to listen to, even for us dorks. Nice vid and tip!
Skip to 5:00 to bypass the blah blah blah
Should I do it to my slash 2wd vxl on 3s?? I use it on a dirt track.
Nice. Need to do that on 4x4 Rustler as well. I have it jacked up for all ways possible for clearance, and mad tight suspension for supercross jumps but now it just flips out at even the sight of a corner coming LOL.
Great content always enjoy your videos we all need to thank your wife for letting you share youre time with us😊
The rpm ones are amazing haven’t broke one in a year
Cool video. Great info. And the hobby room is amazing... just got a 2wd slash vxl . So more slash stuff. Thanks.
Thanks for sharing information for Traxxas 😊
If you wanted them to work on rc
Buy them a race kit.
LOL not really.
I got the lcg chassis not sure I want to lower the chassis anymore than it already is maybe a sway kit would be worth it
this doesn't actually lower the car unless you overdo it. What it is actually doing is limiting droop.
Gotta have the droop though to properly use the physics of the suspension on jumps. The more throw a shock has, the more cusion it can provide on landing. Just thicken the oil on the car. It's way too light out of the box anyway. Then if that doesn't work you can get a sway bar kit for it or fashion one out of piano wire!😁

Yep, this doesn’t limit up travel, it limits droop/down travel/rebound.
Thanks for making this video! Great mod! And learned that my Rustler shock build was lacking the "taco" method.
The imma dork look 👀 lmfao bro I think majority of us can relate haha 😅
I'm late to the game on this but I've never broken a hub carrier on a slash... its always those damn rear stub axles that I break.
same on my stampede
Awesome Advice!!!! Thx! Side note. Wish you were able to zoom your camera in more. But again, this is AWESOME!!!
It would be nice if you included some links of the products you're using. The fuel line and the pliers please.

Very helpful as usual....thanks bro!!
I have a slash 4x4 also, running the 4 pole valeneon motor and esc on 3s with big tires but I cant even drive but for maybe 10 minutes at the most before it over heats. Pretty sure the pinion gear is too big being as it's an 18/50. Just ordered a 12-16 tooth pinion gear set, hoping that will work. I literally FOUND a slash 4x4 and a ruckus ecx 2x4 along with two 3s lipo batteries, 2 nmhi batteries a spare set of tires and a bag full of replacement parts and pieces including a brand new spare valeneon motor and esc combo and a metal roll cage for the slash and 2 transmitters, IN THE DUMPSTER!!!! even found a nmh battery charger with it all also lol only money I have in all of it is some xt90 connectors, and a different TQI transmitter and a charger for the lipos.. I literally accidentally found a new hobby haha
Hey, your videos are very helpful, can you show a current monster slash 2wd build, all videos outdated, tires discontinued? My sons and I are learning from ya!!! Thanks. CJ
Just ordered fox edition slash vxl. Pumped. Down the road i'd like to do the monster truck conversion. So cool.
Thanks Mark, how did you come up with this solution? Just inerested in the story, i've heard of people putting the fuel line on the outside of the shock like a limiter, i think the stock 2wd has them on the rear shocks. Is this a different scenerio that im talking about?
Thanks for that info about the shocks. I have been wondering how to take the body roll down.
So the brakes cleaner will make the plastic look like new without the oil to attract dirt? And should you stay away from spraying it on anything specific..thanks and please respond
1:56 that’s why each one of my rc’s I buy them and then buy the aluminum parts for it.
Boil the Parts for half a Houer it will let them last longer .Boiling ABS is a very Old trick to imrpove durability
But they are not made of ABS and won't be changed in anyway with boiling. That is an extremely old and obsolete trick. Because now they are made from fiber reinforced nylons.
ye thats old school, it wont do anything on the modern plastics
Great vid, how do you choose how much travel you set on the shocks?
"I'm a dork look"..
Lmao- subbed!
Owned my slash 4x4 7 years before I broke my first bearing carrier I've broken a dozen or so A-arms a couple axles but bearing carrier? Once
i love it and i am subscribed - thanks a bunch man! - great tips!! (i just got my first RC!)
I know there are so many SCTs out there but can a traxxas 4x4 race against the big dogs on a track and what must modification should be done to keep up/or beat them?
Hi, Try soaking the rear hub in WD40 for a couple of hours to make it more flexible. As for the fuel line, I would not recommend it for a spacer for inside the shock, it will break apart from bing under pressure all the time. I would recommend either a proper plastic internal shock limiter or silicone shock O-Rings.
Thx brah. 5:29 lol- it’s all good when you label the oil bottle - no ER trip. 7:14 pay attention here
What size fuel line did u use?
They have the blue frame that’s about $30 that make the handling better as well and these 2 together and be amazing. Also that antenna can be shorten to stay under the body and not stick out.
Hey Mark, great vid and tutorial. I get that same "dork" look from my wife too. lol. unrelated question: I have a traxxas slash 4x4 from 2015 and the tires are wearing out. I mainly run on the street and a some dirt. id like to go badlands, but I'm thinking a wiser choice that maybe I just go with bfg mud terrain km2, or the kr2. I don't want to have to lift it, as im running stock shocks. thanks for advice on what preglued tire/wheel combo u think I should go with. thanks
I have a Traxxas Slash, how can keep it from parachuting, driving at it at full throttle 👍
Hey man, this is so awesome. I'm getting this setup on my kids cars soon and thanks for the shock tutorial too. I actually used to help Traxxas with their engineering systems in Waco but never learned to properly work on my own lol. Quick question, one of my sons has a Rustler XL-5 and wants it to be more bash friendly. He saw some of those ProLine Badlands MX28 tires on a VXL and they looked awesome. But I've been told that the XL-5 would likely struggle to push that big of a tire. He's stolen his brothers Stampede Talon tires and that size seems to work (about 4.6in diameter and 2.6in wide). But it seems like no one likes the Talons. Is there another tire you'd recommend for us? I'm fine with regearing it and we aren't racing. Thanks bro!
What’s the best weight of oil you’re using for general use?
Would you recommend this tuning tec. If you have sway bars on your stampede/slash
Reminds me of volume space on a mountain bike shock.
Could you add extra shock o-rings instead??
Hey Mark good video like always. But I wonder if you could help me. I have a 2x4 slash 25 turn motor. I than upgraded it to a monster slash with 2.8 tires vxl motor and 3s batteries. Now I have gone thru 2 tranny housings 4 clutch kits. When I install everything new after 2 minutes after driving the clutch is rally hot and will melt the tranny housing. I have the slipper clutch set to 1/4 turn out so it don’t slip. Still gets so hot that I can not drive the Rc. What am I doing wrong
Is it kinda like the same thing as applying one of those shock collars that came with the truck?
No, adding more shock collars would add more compression and would exacerbate the roll-over problem he's trying to correct. He's basically lowering the car for cheap with this mod.
So what happens if you combine the roll bars with the fuel tube trick? I ordered the wrong sway bar set, I need the larger ones for my VXL 2WD. This is my first RC truck and I converted it to a monster slash because the property terrain is really rugged here at the house. I think the shock setup is not right yet so I hope this helps the handling out. Sounds like it will since youv'e tested it over and over. Got lots of fuel line for my boats. Question I have is this: Does the shock fluid eat the fuel line over time?
Wont that cause issues when bashing big jumps?
@MarkSM do you do this to front and rear shocks?
Just built a hybrid slash/rustler going home to mod the shocks..to all my RC's.
Good for high speed stuff , not so much for bashing or huge jumps , great mod when it serves your purpose though.
