Extra 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 more. High carbon steel is naturally higher in lubricity and lower in 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.
RRP#1200 5 m/m to 1/8 inch Reducer Sleeve required for 1/8 inch shaft motors.
TECH NOTE: 32 pitch and .8 module gears can be used together with no adverse affects such as increased noise or increased wear. The difference is that .8 module gears have a slightly larger outside diameter per tooth, roughly .00027 of an inch.
