The XRAY 305934 narrow pinion gear is made from aircraft-grade duraluminum to give a high strength to weight ratio while maintaining precise tooth geometry. At roughly 1.5mm narrower and about 25 percent lighter than a typical pinion, it helps cut rotating mass without sacrificing stiffness.
Produced on a precision gear machine, this XRAY pinion guarantees tight tolerances and excellent concentricity for consistent mesh. Each unit is chamfered to remove sharp edges and then treated with a hard coating that helps resist wear and keeps the gear running true under extended use.
Designed to pair with spur gears, the XRAY 305934 narrow pinion reduces throttle on/off clatter for a cleaner drive feel. The gear is ready to install out of the package and provides dependable service for competition and club racing setups.
