Losi Aluminum Rear Gearbox Bearing Inserts (2.0)
These inserts look good but you can't see them once installed, they offer no performance gain but they just work away unseen in the back diff adding strength and reliability, I have always used these in my Losi's they are a wise investment.

Very good investment. I installed these after breaking my stock plastic ones.
