The ARRMA GRANITE GROM MEGA Rear Differential Gear Set by GPM MGG1230RS is built to raise toughness in demanding runs. Made from 4140 carbon alloy steel and 7075-T6 aluminum alloy, the components deliver improved wear resistance and long service life. The spiral cut ring gear helps smooth power delivery, and the large bevel gear (30T) and small bevel gear (12T) are surface treated for higher hardness to resist heavy load wear. Differential oil is not included; choose oil viscosity to match your driving style and terrain for best results.
