Accurate 18T pinion made for the XRAY NT1

The XRAY 338518 pinion is manufactured for use with the XRAY NT1, using 7075 T6 aluminium and a protective hardcoat to resist wear. The 18-tooth profile is cut to fine tolerances so the gear runs true and reduces unwanted vibration on tight corners.

Performance that stays consistent

Specifically aimed at competitive hobbyists, the XRAY 338518 combines a lightweight feel with a hardcoated surface to extend service life. Consistent tooth engagement helps deliver repeatable lap times under varying track conditions.

Fast swapping and clear markings

Installation is simple thanks to exact thread dimensions that suit XCA clutchbells in both standard and lightweight options. Each pinion carries an etched tooth count so you can change ratios quickly between sessions.

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.

Can I run this pinion on carpet or asphalt?

Yes, the 18T XRAY 338518 works on both carpet and asphalt surfaces; just adjust gear mesh and ensure your differential and motor setup suit the surface grip levels.

Is re-hardcoating possible after wear?

Re-applying a hardcoat is not practical for hobbyists; if the surface shows significant wear it is better to replace the pinion to preserve gear timing and safety.

How do I check gear mesh correctly?

Use a tracking compound or thin paper method, tighten the pinion to the clutchbell, then rotate to verify even contact along the tooth face and no binding at either end.
