Technical overview of the GPM MGG1230FRS differential for ARRMA GRANITE

This GPM differential assembly is constructed with 4140 carbon alloy steel gear components and 7075-T6 aluminum alloy housings to emphasise durability and consistent meshing under load. The spiral cut ring gear helps reduce shock loads during torque transfer. Critical drive gears include a 30T large bevel and a 12T front bevel that have been surface hardened to improve wear resistance in high-load scenarios. The unit is fully assembled with bearings and installs as a direct replacement for factory parts (#ARA311193 + #ARA311182). Differential oil is not included; follow ARRMA manual guidance for oil selection and fill technique.
