This universal Mod-1 pinion gear fits 5mm RC motor shafts. It comes with a 5mm to 3.175mm shaft coupler, making it suitable for RC cars, trucks, and more. Includes 13T, 15T, 17T, 19T, and 21T pinion gears, five grub screws, a 3.175mm (1/8") shaft coupler, and five hex wrenches.
Made of carbon steel, the pinion gears are harder, stronger, and more resistant to deformation.
The frequency-hardened surface provides higher wear resistance, strength, and less notch sensitivity, making them durable and reusable.
Ideal for replacing pinion gears on devices.
Note: The pinion gears have soft teeth and will not withstand excessive force.
