Real center diff?
 

Did anyone ever make a real center diff for the e revo. The traxxas diff unloads even with 500 k oil.

There are a few guys who have managed to mod a 1/8 scale diff in.

try stuffing silly putty in the diff. it is what some people use to just about lock their diffs. i takes a lot to make silly putty unload

try 600k

if you dont like that then you should return to a solid center, also make sure that the diff is full, if it isnt then it will unload faster
