Precision-Machined 7075 T6 Pinion for Accurate Mesh

The XRAY 348425 pinion gear is made to fit XCA clutchbells and is manufactured from 7075 T6 aluminium for strong, long-lasting performance. This 25T unit provides a consistent tooth profile that helps maintain reliable gear engagement under racing loads. Its larger diameter assists in positioning the engine further from the bulkheads to suit a variety of standard engines.

Controlled Tooth Shape for Reduced Vibration

Cut on a purpose-built gear machine, the tooth form on this pinion aims for smooth contact and lower vibration. The internal fine thread design enables easy assembly on both standard and lightweight XCA clutchbells. Each pinion is marked with its tooth count to simplify gearing swaps and inventory checks.

Selectable Ratios for Performance Tuning

Provided in frequently used tooth counts, the XRAY 348425 allows you to tailor gear ratios to track grip and lap demands. It is a practical choice when upgrading or replacing pinions to optimise acceleration and top speed balance.
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 work with both metal and composite clutchbells?

Yes. The XRAY 348425 fits both metal and composite XCA clutchbells provided they share the same thread standard, offering flexibility across builds.

Is the 7075 T6 material overkill for club use?

Not really. 7075 T6 offers improved wear resistance and strength, which benefits both competitive and regular club racers by extending component life.

How should I store spare pinions to avoid damage?

Keep spares in a dry box, separated by tooth count or wrapped individually to prevent nicks to the teeth and to keep identification markings legible.
