XRAY RX8 18T Lightweight Pinion - Arrowmax AM-RX8-348518  [AM-RX8-348518]

High precision pinion for RX8 applications

The Arrowmax AM-RX8-348518 18T pinion is supplied as an aftermarket motor pinion compatible with the XRAY RX8 chassis. It is CNC machined from 7075-T6 aluminium and finished with a hard coat to provide a low mass, wear resistant gear choice where RX8-compatible pinions are used.

This pinion changes the final drive ratio so you can tune motor load without swapping the spur gear. The hard-coated 7075-T6 core reduces rotating weight while improving surface longevity, and the tooth profile is produced to mesh cleanly with RX8 spur gears when correct mesh is achieved.

Available tooth counts in this Arrowmax series include 16T, 17T, 18T, 19T, 20T and 21T for incremental gearing steps. When fitting to an RX8, verify shaft fit and always check mesh through full suspension droop and steering sweep to minimise premature wear.
