When podium victory counts on a few tenths of second in a serious race, a precision gear is one of essential equipments you may need to put in your car.

The new K Factory special precision spur gear is precisely CNC machined, which provides excellent gear meshing as well as smoother, quieter and more efficient power transmission.


Unlike nylon gears, k factory uses POM material which provides not only extra strength and durability to resist wearing and stripping but also lower friction to insure that your battery can last longer in its peak power range in the crucial last minute. The narrow tooth design even reduces the friction further but no sacrifice on the life or the chance of damage with this remarkable material.

Have you had experience of finding different screws or adding washers (or shims) on your gears to avoid part-to-part contact or scratch? Or struggled on finding right position between spur and pinion? The new offset design (one side is flat, the other is sunk) gives the racers additional space for various gear installation, and wider selection of your favorite pinions.
