XRAY RX8 17T Pinion for On-Road Tuning - Arrowmax AM-RX8-348517  [AM-RX8-348517]

Aftermarket pinion for the XRAY RX8

The Arrowmax AM-RX8-348517 17-tooth pinion is an aftermarket motor pinion intended for use with the XRAY RX8 chassis, produced from 7075 aluminium with a hard coat to help resist wear in standard on-road applications.

This 17T choice is one option in a line of pinions aimed at simple gear ratio tuning; swapping pinion tooth counts against the spur gear shifts the drivetrain ratio and changes acceleration and top speed characteristics. Multiple tooth counts are available so drivers can swap pinions to tune performance without replacing other components.

Fitment advice: ensure correct mesh to the RX8 spur gear and set backlash to the usual on-road range, recheck alignment after a few runs, and replace the pinion if teeth show measurable wear. The hard-coated 7075 construction seeks to balance reduced mass with improved tooth life for regular motor gearing work.
