Race-Grade 19T Pinion Built for XCA Systems

The XRAY 348519 19T Aluminum Pinion Gear is intended for competitive hobbyists who prioritise consistent drivetrain behaviour. Constructed from 7075 T6 aluminium with a protective hard-coating, it is designed to retain shape and resist surface wear under regular track use.

Accurate Tooth Geometry and True Running

Produced on precision gear machines, each unit has finely formed teeth to aid smooth meshing and efficient torque transfer. The internal thread makes installation on XCA clutchbells straightforward, helping to maintain concentric rotation whether you choose a standard or lightweight clutchbell.

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 choose the right tooth count for track conditions?

Select tooth count based on desired top speed versus acceleration for the circuit; smaller pinions favour acceleration, larger tooth counts favour higher top speed when paired with the same spur.

What benefits does the hard coating give?

The hard coating helps reduce surface wear and preserves tooth profile for longer, which supports consistent gear mesh and performance over time.

How often should I replace an aluminium pinion?

Inspect regularly for pitting or rounded tooth edges; replace when wear affects mesh quality or if you notice increased vibration or noise during runs.
