Aluminum Pro Pinion Gear 1/8" Bore 48P 31T (RRP1331)

The Aluminum Pro Pinion Gear, 31 teeth, 48 pitch, with a 1/8-inch bore, is a precision pinion designed to mesh with a compatible spur gear in RC cars and trucks, transferring power from the motor to the drivetrain. It’s machined from aircraft-grade aluminum, lightened, and double black-anodized for durability, with the tooth count stamped on the gear for quick identification. A set screw is included to secure it to the motor shaft.

Primarily intended for on-road use, it can also handle off-road conditions when paired with the right spur gear. The 1/8-inch bore fits standard motor shafts, and the rugged coating resists wear in demanding driving situations, helping maintain consistent gearing and drivetrain performance over time.
