RE: Recommendations for Beefier Tmaxx Diff
That is the exspensive route but pretty much the best one. Rebuilding with Robinson gears isnt very exspensive and is very stout. Robinson gears and Kipster cups with an aluminum case will take care of you for good. Just using the robinson gears will do very well though. I wouldnt get the spool, it will handle like crap on the track.
