High-performance pinion gear manufactured from special lightweight aircraft duraluminum to have lowest weight. The pinions are manufactured by XRAY on a specially modified precision gear machine, which has ultra-precise tolerances and assures unparalleled concentricity. After machining, the pinions have all their edges chamfered and then are run-in. The pinions are then specially treated to give them an even hardcoat so they stay absolute true for a long time.
With all of this preparation, you can feel confident in mounting the pinion right from the package, and get excited from getting leading edge pinion design and production. The pinions run great with any spur, but with an absolute spur even throttle on/off noise disappears!
