Tamiya 22-23T RC Pinion Gear - 50357

The Tamiya 50357 pinion gear set supplies two pinion gears — a 22-tooth and a 23-tooth — for use in Tamiya electric RC cars that use a standard 48-pitch drivetrain. Pinion gears sit on the motor shaft and drive the spur gear, so the tooth count you choose directly affects your final drive ratio: a 22T pinion gives slightly more torque and acceleration, while a 23T pinion raises top speed. Having both options in one pack lets you tune the drivetrain to the track layout or terrain without needing to order two separate parts. These are genuine Tamiya spares, making them a reliable choice for maintaining or adjusting the drivetrain on compatible Tamiya models.
