The XRAY 305974 Narrow Pinion Gear is engineered for hobbyists who want accurate, dependable power transfer. Made from aircraft-grade aluminum, this pinion is 1.5mm thinner and about 25% lighter than standard pinions to reduce rotating mass without sacrificing strength.
Produced on a specially modified precision gear machine, the XRAY 305974 maintains tight tolerances and excellent concentricity. Edges are chamfered and the part receives a hardcoat treatment to resist wear and keep the gear true under load.
When used with XRAY spur gears or compatible aftermarket spurs, this narrow pinion runs smoothly with reduced noise during throttle transitions. Its slim profile helps preserve gear alignment and responsiveness in tuned drivetrains.
