The ARRMA GRANITE GROM MEGA Rear Differential Gear Set by GPM MGG1230RS brings rugged components to small scale monster trucks. Fabricated from 4140 carbon alloy steel together with 7075-T6 aluminium alloy parts, the set increases resistance to wear and extends service intervals. The spiral cut ring gear promotes efficient torque transfer, while the 30T large bevel and 12T small bevel gears receive surface hardening for reliable performance in high stress situations. Differential oil is not supplied, so fit oil to suit your preferred handling and track conditions.
