Uxcell M1 Mod1 Pinion Gear Set, 5mm Shaft, 13T, 14T, 15T, 16T Motor Gears, Hardened Steel Pinion Gears with 3.17mm Coupler for RC Cars (4 Pieces)

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 four pinion gears (13T, 14T, 15T, 16T), four grub screws, a 3.175mm (1/8") shaft coupler, and a hex wrench. Made of carbon steel, the pinion gears are harder, stronger, and more resistant to deformation. The surface-hardened parts provide 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. Universal Mod-1 pinion gears fit 5mm RC motor shafts.
