    Onto my 6th diff now....

    Why does my summit keep stripping diffs? Im onto 3 front and 3 rear ones now. They last about 20 battery packs and then they are toasted.

    My stampede on the other hand I hammer it all day and the diffs are fine.

    I've heard of it, but not sure what it does. I usually just get the guy at the hobby store to fix the things that take a while to do. Never had to rebuild a diff myself yet.

    It explains the how and why... it is not a cure-all, but it does reduce the amount of diff issues.
    Whatever it is I just said... I could be wrong.

    I don't even know how you could break the front diff, but anyway, shimming can help, but what is going to help most is loosening the slipper a little, not hammering the throttle everytime you take off and most importantly, releasing the throttle when you land and when you are about to hit something.

    I haven't stripped one diff yet. My kid on the other hand has stripped 3 already.

    Buying the $4 shims will save you lots of money in the long haul, especially if you like fast acceleration.
    With great brushless comes great responsibility.

    Ok anyone have specific instructions for shimming the diff? I'll get the hobby guy to do it. I just stripped another one after 2 battery packs, so im about done with this car until the issue is fixed haha

    Google the part number that is listed in the link of post 5. Most hobby shops should be able to get them.

    Jimmie how long you think the diffs will last with it shimmed? I got 2 runs out of my last diff, just about sold the thing after that haha

    I had 200 or so runs on my 1st set of shimmed diffs without any issues... in a Revo running buggy rear Hawgs on 2S.

    I think part of my issue is the grass gets wrapped around and puts too much stress on the drivetrain.

    Just got an emaxx brushless yesterday and it was ripping through the deep grass no problem

    Comparing a 1/16th and a "1/10th" (should be an 1/8th) in how they handle terrain is like expecting a Ferrari to run in sand.

    I shimmed my diffs according to that post and probably have 50+ packs thru it and I am a basher, running stock batteries, but I agree with post 7 stay off the throttle when landing it and on high traction areas don't smash the trigger when tacking off, I havn't had any issues and haven't really broken anything either (knock on wood) lol
