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 18T, 19T, 20T, 21T, and 22T 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 surface-hardened treatment makes them more wear-resistant, stronger, and less sensitive to notches, 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.
