hum..isnt this for rc10s ? yeh i have been having major problem with my tc5 diff , it's really a pain to rebuild , anything that can ease the process is certainly help..
Not Specifically, It's Associateds generic diff screw, they've used it in many of their vehicles. It's MUCH better than the stock TC5 diff screw and nut.
Here's another link to it from Associateds site
