HPI Racing 24T (48DP) RC Pinion Gear - HPI6924

The HPI Racing 6924 24-tooth pinion gear (48DP) is a replacement drive gear designed for use in HPI Racing RC cars that run a 48 pitch drivetrain. Part number HPI6924, this pinion gear fits directly onto the motor shaft and meshes with the spur gear to transfer power to the drivetrain. If your current pinion is worn, chipped, or you need a specific tooth count to tune your gear ratio, this is the part to reach for.
