Stock revo diffs are poop.

Remember you are running a tiny setup on yours.

If you build them in aluminum (the diffs) with proper shimming they can last a while, but they are not considered amazingly strong. Mike mentioned that racers replace the diffs after the race with new ones, just in case.. Meaning they don't put a lot of faith in them.
