ARRMA ARA311166 Center Diff Case Set

This ARRMA center diff case set provides the replacement housing components for the Mojave 4S center differential. The center diff splits drive power between the front and rear axles, and its case is what holds the internal gears in precise mesh while containing the silicone fluid that controls the diff's action.

The case components are molded from tough composite to the exact factory specification, sealing correctly against fluid weep and locating the diff's bearings and gears precisely.

Diff cases wear at their bearing bores and sealing faces over a hard truck's life — a worn case lets the diff run loose and leak fluid, changing how power splits under throttle. A fresh case set during a diff rebuild restores factory-tight operation.

Fitment is the ARRMA Mojave 4S platform — confirm against your model's exploded parts diagram. The package includes the center diff case set.
