The XRAY 305977 Narrow Pinion Gear is machined from high-grade aircraft duraluminum, delivering a lightweight option for tuners aiming to refine handling and response. At 1.5mm thinner and roughly 25% lighter than a standard pinion, it reduces rotational mass to help acceleration and drivetrain efficiency.
Cut on XRAY's specially-modified precision gear machine, each pinion is produced to tight tolerances for excellent concentricity. All edges are chamfered and the gear is hard-coated to resist wear while holding its shape during heavy use.
Designed to mesh smoothly with spur gears, this narrow pinion works particularly well with XRAY spur sets to minimise throttle on/off noise and smooth power delivery. Straight from the box it reflects careful design and manufacturing for race-ready performance.
