    I forgot to mention that I NEVER use the "self-righting" feature on my X-Maxx.

    I just nuked both front and rear stock diffs on my X-maxx running 8S on a 1090kv. Got about 6 inches of air at full throttle while in the grass and heard 'em both go POP.

    Got aluminum diff covers, cases and KD gears on the way.

    I might be giving it a try before going for KD diffs..
    Traxxas part # 7781. Comes with 2 shims meant for the spider gears but they fit behind each pinion

    Mine weren't shimmed, but I will shim them when I rebuild them.

    Thanks,
    How many did you used for each pinion?

    Just one per pinion, it part number comes with 2 so enough to do both diffs. It pushes the pinion out just enough to make more contact with the ring gear. I believe shimming, never using the self-righting feature and making sure to always let of the gas before I land a jump is the factors in my never having broken a diff yet
