Lightweight Precision Narrow Pinion

The XRAY 305931 narrow pinion gear is machined from premium aluminum to provide a lightweight drivetrain option for RC racers. This 31T pinion is 1.5mm thinner and about 25% lighter than standard pinions, helping cut rotating mass while preserving strength.

High-Precision Production

Produced on XRAY's dedicated gear machines, these pinions feature ultra-tight tolerances for excellent concentricity. Edge chamfers and a hard-coating finish reduce wear and help the gear hold its true shape through repeated runs.

Compatibility and Quieter Running

Designed to mate with a wide range of spur gears, the XRAY 305931 narrow pinion works especially well with XRAY spur gears to help lower throttle noise and deliver a smoother power transfer. It is ready to fit and use right out of the package.
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 the XRAY 305931 suitable for all 1/10 scale cars?

This pinion is designed for broad 1/10 scale compatibility and pairs best with XRAY spur gears; check pinion bore and spline count to confirm fit for your chassis.

What advantage does the hard-coating give?

The hard-coating increases surface hardness and wear resistance, which helps maintain gear geometry and reduces the risk of premature tooth wear under load.

How should I maintain the pinion for best life?

Regularly inspect gear mesh, keep the teeth free of debris, and check the hard-coating for wear; replace if you notice chipped teeth or significant rounding.
