HPI Racing 77T (48DP) RC Spur Gear - HPI103371

The HPI Racing 103371 Spur Gear 77T (48DP) is a direct-fit drivetrain replacement gear designed for HPI Racing RC cars that use the 48 pitch gear standard. Spur gears are a core part of any RC car's drivetrain, working alongside the pinion gear to transfer power from the motor to the wheels. When your existing spur gear strips or wears, swapping in an OEM-spec part like the HPI103371 restores drivetrain performance without the need to re-mesh or recalculate gear ratios.
