The GPM MGM2122 set replaces standard steering blocks and rear hubs on the ARRMA MOJAVE GROM MEGA DESERT TRUCK with 7075 alloy parts intended to reduce component deformation and maintain steering geometry under load. The kit includes front steering blocks and rear hubs sized to match existing mounting points, allowing a direct swap and minimal setup changes. This upgrade is aimed at hobbyists seeking a robust solution for repeated high stress running.
