Differential Outdrive for ARRMA 1/16 MOJAVE GROM / 1/14 TYPHON MGM039S by GPM  [MGM039S]

Durability-focused outdrive for ARRMA models

The MGM039S outdrive is an aftermarket RC replacement crafted for ARRMA compact desert trucks and buggy differentials. Made from medium carbon steel and precision machined, it is designed to resist wear at the interface with CVD or dogbone shafts and to help maintain smooth rotation of the differential internals.

The component installs into the stock differential housings used on the indicated ARRMA models and serves as the coupling between rotating drive shafts and the diff internals. It is intended as a direct substitute for factory part ARA311193; check the original piece for fit and orientation before final assembly. Use this part when you want extra strength at the contact points while keeping the original geometry unchanged.
