High precision 18T pinion tailored for XRAY NT1

The XRAY 338518 pinion gear is purpose-built for the XRAY NT1, machined from durable 7075 T6 aluminum and finished with a hardcoat for extended life. Its 18-tooth profile is produced to tight tolerances to minimise runout and vibration, helping maintain smooth gear mesh during competitive runs.

Built to last without compromising speed

Made with racers in mind, the XRAY 338518 balances strength and lightness to resist wear while keeping rotational inertia low. The hardcoating reduces surface abrasion so the gear keeps consistent engagement lap after lap.

Quick fit and easy ID

Mounting the XRAY pinion is straightforward thanks to the accurate thread fit for XCA clutchbells, both standard and lightweight types. Each unit is laser or etch marked with its tooth count for fast identification when swapping ratios in the pits.

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 the XRAY 338518 fit non NT1 chassis?

The gear is designed for the XRAY NT1 geometry and thread standard; it may fit other models that use the same clutchbell pattern, but check shaft diameter and spline counts before fitting.

How should I maintain the hardcoating?

Keep the gear free of grit and inspect teeth regularly. Clean with a soft brush and mild solvent if needed, and avoid aggressive filing to preserve the hardcoating surface.

What benefits does 7075 T6 bring to pinion gears?

7075 T6 provides high strength-to-weight ratio and good fatigue resistance, giving a robust pinion that keeps weight down while resisting deformation under load.
