Description
FAQ

Race-Grade Narrow Pinion from XRAY

The XRAY 305989 Aluminum Narrow Pinion Gear is aimed at racers and tuners looking for exact gear behaviour and consistent performance. Advanced machining yields very tight tolerances and high concentricity so the gear runs smoothly with minimal noise.

Engineered Duraluminium Lightness

This pinion is formed from aircraft duraluminium, offering both rigidity and low weight, roughly 1.5 mm thinner and about 25% lighter than standard units. The lighter component reduces rotating inertia and helps the car feel more responsive out of corners.

Hard-Coated Teeth for Extended Use

A specialised hard-coating process increases tooth longevity and keeps the gear true under extended service. Chamfered edges and an initial running-in step produce quiet, consistent mesh, and it is particularly effective when matched to XRAY spur gears.

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.

Can the XRAY 305989 handle brushless power systems?

Yes, the precision machining and hard coating allow it to perform well under modern brushless torque, but ensure correct mesh and check after heavy runs.

How do I check gear mesh with this pinion?

Set a small amount of lash with a strip of paper, tighten mounts, then remove the paper and verify smooth tooth contact across the mesh for quiet operation.
