Robinson Racing Products 8715 Hard .08 Bore Steel Pinion 15T fits 5mm Shaft

xtra hard high carbon motor pinions are built to last with our hi-performance GEN3 steel slipper units. Made from high carbon steel and then heat treated to increase the hardness of the surface even further. High carbon steel is naturally lower in friction and adhesion than milder grades of steel making these gears ideal for use with metal spur gears. All pinions precision machined and stamped with the number of teeth. One 4 m/m set screw included. 2 m/m allen wrench (NOT INCLUDED) fits the 4 m/m set screw. Can be run on motors using a 5 m/m motor shaft including Traxxas, Associated, and HPI models or for any heavy duty application.
