The XRAY 305973 Narrow Pinion Gear uses lightweight duraluminum to reduce weight without losing robustness. Being 1.5mm slimmer and about 25% lighter than conventional pinions, it helps reduce inertia on drive shafts for quicker spool up.
Cut on specialist gear machines, the XRAY pinion attains tight tolerances that improve concentricity and tooth runout. The chamfered tooth faces and hardcoat treatment work together to resist surface wear and maintain accurate engagement.
Designed to pair well with many spur gears, including XRAY spurs, this narrow pinion reduces gear whine and promotes smoother transitions under throttle. It is suitable for builders seeking reliable mesh across different setups.
