Compact Pinion for Lighter Rotating Mass

The XRAY 305971 Narrow Pinion Gear is designed for pilots who prioritise reduced rotating mass and precise drivetrain response. Constructed from aircraft-grade aluminium, it is 1.5mm thinner and approximately 25% lighter than standard pinions to keep weight low.

Accurate Gearmaking

Made on precision gear machinery with tight manufacturing tolerances, this pinion ensures strong concentricity and reliable tooth contact. The chamfered teeth and hardcoat process add durability for regular running.

Plug-In Compatibility

Built to work with a broad range of spur gears, including XRAY spurs, the narrow profile supports smooth throttle control and reduced noise. It arrives ready to install with minimal setup time.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is special lubrication needed for this aluminium pinion?

Metal pinions normally do not need grease on the teeth, but ensure the spur is compatible and occasional inspection for wear is recommended. Use light gear lube if your setup calls for it on mating surfaces.

Will it fit smaller nitro cars as well as electric models?

Fitment depends on shaft diameter and module, not fuel type. If the motor or clutch shaft and tooth profile match, the XRAY 305971 can be used across different drivetrains.

Should I expect a change in drivetrain temperature?

A lighter pinion can slightly reduce drivetrain load, but temperature changes are usually negligible. Keep an eye on mesh and bearing condition during extended runs.
