The XRAY 305982 Narrow Pinion Gear is a purpose-made component for tuners seeking reduced rotating mass and consistent tooth engagement. Made from aircraft-grade duraluminum, this pinion is 1.5mm thinner and about 25% lighter than conventional gears.
Produced on XRAY's specially adapted precision gear machine, the 305982 achieves excellent concentricity and tight tolerances. The manufacturing routine includes chamfered edges, a controlled run-in and a hardcoat to keep the gear profile stable under prolonged running.
When installed with spur gears, especially XRAY spurs, the 305982 can reduce throttle on/off noise and smooth power delivery. It is designed to match common spur profiles for wide compatibility across builds.
