Awesome vid bro!👊Just ran across this vid looking for possible diff upgrades! I'll definitely try this on mine as I toasted both diffs during my last 2s bash! The jumping is what did it since I'm sure there was lots of flex and movement in the diff housing. Have you had good luck wit this setup?
Eric, Thanx so much brother. This is awesome you are commenting on my vid. This upgrade is solid. I havn t run brushless but larger 380 motor with different pinions and really holds up. I was ready to trash the rc untill i did this. Let me know if you have any questions.
@@phillybrc Thanks for the tips buddy! I'll look into the metal cases too! Such a fun little rig just needs a stronger diff setup for the big power!😁💪💪
I have the same car for my son. We’ve had no issues with the diffs. I did notice you run your diffs dry. I put a coating of automotive bearing grease on the gears in the diff. They run quieter that way. Not sure the grease helps prevent stripping though. We break arms and driveshafts from jumps. Stock servo gears are rubbish too. Waiting on a new servo. Anyway, thanks for the vid!
Thanx for the input! Yes, the diffs are currently dry, only because i feel i have tried different lubes and had given up! Some people have many issues, many have none...strange. Nonetheless, these shims have helped us greatly! Thank you for watching.
@@phillybrc This gets me wondering if it’s a problem with the diff case on the chassis. I see that it’s a replaceable part. Perhaps some fit loose and some fit snug? Anyone ever try that on the forum you follow? Part#7530
@@scrastocarina It must be, so weird that it s rock solid for some, and terrible for others. I had hopes of 2s for this, now I m sceptical. Thank for the input, I will look into it.
I loved mine for the first week, but now I keep blowing diffs over and over... Stock power system but keep blowing diffs on the front while running on dirt. My father has a prerunner that he beats the hell out of with no issue. Mine as soon as I put it back together and hit the gas it rips another diff out of it...
Thank you so much for the part numbers of the shims. My son hasn’t had any issues yet but I noticed the differential gear play was abysmal during a spur gear replacement and we are upgrading it to a 2-3s Hobbywing ESC and brushless motor 😬
I got a teton used. Upgraded to 3s right away and Broke all the diffs. Lasted for about 20 mins with the new metal versions from traxxas. Now the front diff is toast again. I just bought these shims. I’m hoping it with help. Thanks for posting information about it
@@phillybrc hobby wing 60amp esc and a 4800kv amazon 2435 can motor. I’m impressed it runs on grass. I walk with my family driving this around the neighborhood with a light bar on it. Everyone’s like wow. It scoots
@@phillybrc I just finished installing all the shims today. I played with it for about 5 mins. It feels tighter now. Feels good. I’m gonna bash it tomorrow and let you know how it goes. I’m sure it will hold up better than not having shims. Thanks again .
I just got my prerunner last Friday and today (Monday evening) I really drove my prerunner hard with the speed gear upgrade and I already stripped my rear diff. And when I say drove it hard, I mean like jump off the side walk and full throttle up and down the street. I heard it strip when I break hard from high speed.
Ya, i found this to be real problem area also. Shimming is a huge improvement. My son still loves this car but it needs maintenance… i guess they all do lol
@@phillybrc well i put a ez run brushless in and its way to fast lol...if I glued the tires it would flip so im using the tire slip as a poor mans clutch lol. Im actually heading up to goat hobbies to see if i can mod the 2wd set up like losi where all the gears line up like the standard bandit or rustler 2wd gearbox...oh and carpet is really what 2wd like this is for because it tends to oversteer ...smooth courts are nice to if there not to slippery.
I'm considering this vehicle and appreciate the tip. Working with what you had, I probably would have placed both shims on the ring gear side. Or purchased twice the shims and doubled the ring side, single opposing. Why no grease? Couldn't hurt. Probably fine stock but I plan to go brushless so I won't be screwing around when it comes to the drivetrain. Do you think this car is worth it? It's got some stiff competition for a lot less money. I prefer not to jump on the build-house clones everyone is nuts about but if I have to spend $150 for the car and another $100 to get it 'right' I'm going to have a lot to consider. Thanks.
It s been a great car but considering the repairs i ve done, I would just buy a brushed version of the Granite, Typhon or Senton by Arrma. Yes, I do grease now. I didn t have any grease at the time and stores were closed, so I went dry. Thanx for watching!
@@phillybrc Thanks for your reply. I already have several brushless larger scale models, one of them being an Arrma product. My issue is I need to find another 1/18 or 1/16 to bash with some friends that run this particular scale. My AE 18T is not a good basher and parts are becoming scarce now so I have to shelve it. Doesn't seem to be much diversity in this scale anymore.
@@monosurge Having said that, I am a fan of this rc. Once you shim diffs well its great. Parts are readily available and easy to repair. I like having a 1/18th for the simple fact you can throw in the trunk and have fun, less cumbersome than bigger scale. Great for my kids also.
@@phillybrc One last question I'm having trouble getting a straight answer on. How many of the gears on this come stock metal and how many are plastic? I'm trying to fill up a cart with enough upgrades to make it an all metal drivetrain, including the output cups. The website says all metal gears. Some videos show plastic bits here and there. It's a bit confusing. Thanks again!
Works great! Havn t stripped a gear since. All the info and instructions are in the video, hard to explain through text. 1 shim for the input gear and 1 shim on each side of differential assembly. Thanx!
Good video. Where did you acquire the shims from? And, did you apply any grease to the gears prior to closing it all back up? If so, what did you use? Thanks in advance. 😎👍🏼
Hi. Someone at my work made them for me since they were expensive and hard to find. They became available soon after i made the video. I use Red &Tacky on diff gears. I don t use grease on the spur and pinion, dirt sticks to it and ruins the gears
@@phillybrcI apologize. I didn’t recall seeing the packages in the video. So, did you end up putting them behind the bearing (closest to the interior diff’s, or outer close to where the driveshaft inserts? Did you only use one per side or did you end up adding another one? Do you use these shims on any of the other LaTrax vehicles? Thank you so much for your time and sharing the info.
Yes it did! I was stripping gears often. I havn t stripped one since! Games changer. Keep in mind im running stock set-up but huge improvement. Let me know how it goes.
@@phillybrc technically they work the same right side up or upside down assuming they are bled properly. The main reason to have them the normal way is so less dirt collects where the shaft goes in to the shock body.
@@phillybrc alright and I believe I need to shim my prerunner because I upgraded to brushless. With a castle creations sidewinder micro 2 5300kv motor and I don't want the differential to be stripped.
I got this truck for my son about a month and a half ago and so far he’s gone through three differentials and two of the main black plastic gears .. I don’t know what to do anymore..
Hey Manny, i had the same issues. Shimming these diffs made big difference for me. Getting rid of the play in the gearsets is critical. It s odd with these trucks...some people have plenty of gears issue, some have none. Strange. This mod does help though. Let me know how you make out. Thanx

@@jameshays2343 Fair sir. I think you caught me on a “short” week also. LOL. Unfortunately emotions get lost through text. Congratulations on being surrounded by all those kids!
My teton those gears keep shredding I think the motor haveto much power 🤣🤣 I bought 2 gears that are solid $40 each aluminum and steel so let see if they hold or something something else break
That is the wrong place to put this shim. For the shim to work there it will have to contact the trans case. It will also contact the inner race of the bearing, the inner race will be spinning so you are adding friction to your drive train. To shim the ring gear closer to the pinion you put the shim on the short side before the bearing.
@@RobynTapps Ya, I totally agree. Funny how some people have no problems with stock diffs and some do. Comes down to manufacturing tolerances is my guess.
Mine Teton has a hobbywing esc&motor and its crazy fast but it keeps tearing up the diffs or drive lines even the nicer blue aluminium ones with a 3s battery it will do backflips if u just punch it lol
What pinion for brushless? How many teeth with a 60t steel spur. The net i not helping, and I'm not seeing hardened steel pinion in 2.3mm bore size. It's frustrating.
I state that i would makes some changes but was limited because these shims were made at my work and dimensions were off a little bit. Make a video, i d like to see how you do it.
Thanx for the input. I actually state that shim should be inside of bearing, since mine were made not bought, the inner diameter didn t quite allow for that to happen
