Race-Ready XRAY 348418 18T Pinion with Hard Coat

The XRAY 348418 18T Aluminum Pinion Gear is designed for drivers who want durable, predictable gear engagement. Forged from 7075 T6 aluminium and treated with a hard coating, it holds its profile under load and provides consistent performance session after session.

Optimised Tooth Profile

The larger diameter allows more space between the motor and bulkheads for many standard engines. Manufactured using precise gear cutting methods, each unit has tight tooth form tolerances and low runout to reduce vibration and improve drivetrain efficiency. Internal threads are finely made to fit both standard and lightweight XCA clutchbells easily.

Quick-Read Etching and Setup Flexibility

Tooth counts are etched on the face of the gear for fast identification so you can swap sizes at the track without delay. Offered in a selection of common sizes, this pinion helps you refine gear ratios for varying track layouts.

Specifications

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 does the larger size help on installation?

The increased diameter provides space that can allow some engines to be mounted a little further from the bulkheads, useful in tight chassis arrangements.

Will this work with aftermarket clutches?

It threads to standard XCA clutchbell specifications, so compatible aftermarket clutchbells made to the same standards should fit without modification.

What maintenance keeps it lasting longer?

Regularly clean debris from teeth, check mesh and backlash, and avoid abrasive dirt contact to prolong the hard-coated surface life.
