XRAY 305920 Narrow Duraluminum Pinion 20T/48 Hard Coated  [XR-305920]

Fine tuned narrow pinion from XRAY 305920

The XRAY 305920 Narrow Pinion Gear is designed to suit T4 2017 Specs setups where cutting rotating mass matters. Forged from lightweight aircraft-grade duraluminum, this pinion is 1.5mm slimmer and roughly 25 percent lighter than regular pinions, offering a clean weight saving while remaining tough.

Precision machining and edge protection

Using XRAY's modified precision gear equipment, the narrow pinion is manufactured to tight tolerances to ensure true concentric rotation. The teeth are chamfered and receive a hardcoat treatment to protect the cutting edges and help maintain gear accuracy under load.

Smooth engagement and lower drive noise

Engineered to work with a variety of spur gears, the XRAY 305920 Narrow Pinion Gear is particularly compatible with XRAY spurs, helping to achieve smoother engagement and less audible throttle noise for a neater drivetrain sound on runs.
