ARRMA Diff Planet RC Differential Gear - ARAC4027

The ARRMA AR310865 Diff Planet Gear set (style code ARAC4027) is a genuine OEM replacement for the differential assembly across a wide range of ARRMA 1/10 and 1/8 scale RC vehicles. Planet gears sit at the heart of the differential mechanism, allowing each driven wheel to rotate at a different speed during cornering. When these gears wear or strip under hard bashing, the differential loses its ability to distribute torque correctly, making this a direct and necessary replacement to restore normal drive behaviour. Four planet gears are included per pack, matching the standard count used in ARRMA differentials.
