Bulletproof revo tranny?

[Trick440]

I'm look at this .. This is the output gear isn't it? And I just ordered a center diff., the center diff. replaces this output shaft, I think, does this mean I'm going to be burning up center diffs?

Any ideas on why this keeps happening?

It seems to happen after high speed runs, only other thing I can think of is my remote antenna is bent and its making the car twitch and sometimes stop a quick, but it didnt seem to do that right before it broke, but I could of just not noticed.
