Precision-machined 18T pinion for XRAY RX8

The Arrowmax AM-RX8-348518 18T pinion is produced from premium 7075-T6 aluminium to offer a solid mix of stiffness and reduced mass. A hard-coat finish helps protect the teeth under prolonged running and hard landings.

Engineered for low mass and longevity

7075-T6 aluminium gives this pinion a favourable strength-to-weight ratio, helping lower rotational inertia while resisting wear. The protective coating preserves the tooth profile for consistent performance lap after lap.

Compatibility and gearing choices

Specifically matched to mesh with XRAY RX8 spur gears, the pinion sits within a tuning range typically spanning 16T to 21T. Changing tooth counts lets you refine acceleration or top speed depending on surface and course demands.

How do I check this pinion fits my motor shaft?

Verify the pinion bore diameter and set-screw position against your motor shaft specification. If needed, use the correct bushing or shim to ensure secure seating.

Is the hard coat necessary for club racing?

The hard coat extends the service life of the gear, which is beneficial if you run often or on abrasive surfaces. It also helps maintain smoother mesh over time.

Can I change tooth counts to suit different tracks?

Yes, the line offers options from 16T to 21T so you can tune for shorter circuits or faster layouts by adjusting the pinion size.

Does this pinion need special installation tools?

Standard small hex drivers and a motor holder are typically all you need. Ensure the set screw is torqued correctly and check mesh with a pencil or gear mesh gauge.
