Install the GPM differential gear set to upgrade the strength and longevity of your ARRMA GRANITE. The kit pairs 4140 carbon alloy steel gear faces with 7075-T6 aluminum alloy housings and uses a spiral cut ring gear to promote even torque transfer. The 30T large bevel and the 12T front pinion are surface treated to increase hardness and resist wear during heavy runs. This is a fully assembled differential with bearings included, designed to replace factory parts (#ARA311193 + #ARA311182) directly. Differential oil is not included; refer to the ARRMA manual for recommended oil type and filling guidance.
