Precision Narrow Pinion for Track Use

The XRAY 305971 Narrow Pinion Gear suits drivers aiming for precise throttle response and reduced rotational mass. Manufactured from high grade aircraft aluminium, it is 1.5mm narrower and around 25% lighter than conventional pinions, helping improve handling dynamics.

Quality Gear Production

Produced with strict tolerances on specialist gear machinery, this pinion offers reliable concentricity and consistent engagement. The chamfered tooth edges and hardcoat treatment boost surface toughness for longer life.

Smooth Integration with Spur Gears

Compatible with many spur gear options including XRAY parts, the narrow design aids smooth power delivery and cuts unwanted gear noise. It is supplied ready to fit for quick servicing and track use.
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.

How do I verify the pinion matches my spur gear?

Confirm the module and tooth count match and check the bore size against your motor shaft. Once the basic specs align, set mesh carefully and test at low power.

Is this pinion suitable for club racing use?

Yes. The XRAY 305971 is aimed at competitive environments where lower rotating mass and precise mesh help lap consistency. Regular inspection keeps performance reliable.

What maintenance does the hardcoat surface require?

The hardcoat is low maintenance; simply monitor tooth condition and mesh. Replace the pinion if you spot significant pitting or deformation after extensive running.

Will the narrower face affect spur life on high power setups?

Under high loads, a narrower face can concentrate forces slightly more than a wider pinion. Use compatible, well-made spur gears and maintain correct mesh to avoid premature wear.
