The XRAY 305924 Narrow Pinion Gear uses aircraft-grade duraluminum to keep mass down while holding strength. At about 1.5mm thinner and roughly 25% lighter than conventional pinions, it trims rotating weight to help with acceleration and response.
Made on a specially modified precision gear machine, this pinion is produced to tight tolerances for true concentricity. Each unit receives chamfered edges and a run-in process, then a hardcoat treatment to increase surface resistance and long term stability.
This narrow pinion pairs well with a wide range of spur gears and is particularly smooth when matched to XRAY spur gears. The narrower profile helps reduce throttle on/off clatter for a quieter, more consistent drive feel.
The XRAY 305924 arrives prepared for immediate installation, so you can get it on your car and tune mesh quickly. Built for hobbyists who expect precise fit and reliable performance from the gearbox components.
