Engineered Gear Accuracy

The XRAY 305970 Narrow Pinion Gear is a clear upgrade for those wanting to trim weight and keep precise gearing. Made from aircraft duraluminum, this pinion is 1.5mm thinner and about 25% lighter than standard pinions, helping reduce rotating mass and improve drivetrain response.

Precision Machining for True Rotation

Produced on a specially modified precision gear machine, the XRAY 305970 is held to tight tolerances to maximise concentricity. The careful manufacturing process helps the gear run true lap after lap, reducing vibration and inconsistent meshing.

Hard-Coated for Long Service Life

Each pinion is chamfered after machining and then receives a hard-coated finish to guard against wear. This treatment helps the gear retain its precise profile and prolongs usable life under regular track and club running.

Smoother Mesh with Compatible Spur Gears

Designed to mate cleanly with a variety of spur gears, the narrow profile of the XRAY pinion helps lower throttle on/off noise and produces a quieter, smoother shift in power when paired with matching 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.

Will this pinion fit my existing gearbox?

Check your motor shaft and gear mesh clearance; the XRAY 305970 fits most setups that accept a narrow pinion, but confirm shaft diameter and tooth count before fitting.

How does the hard-coating help in everyday use?

The hard-coating improves surface toughness, reducing wear from spur interaction and helping the gear keep its concentric profile for longer between replacements.

Any tips for installing the pinion to reduce noise?

Set a correct gear mesh with a small feeler or paper method and chamfer the spur gear edges if needed; pairing the XRAY 305970 with an XRAY spur gear typically lowers throttle noise.
