XRAY RX8 17T Motor Pinion for Gear Tuning - Arrowmax AM-RX8-348517  [AM-RX8-348517]

Motor pinion made for the XRAY RX8

The Arrowmax AM-RX8-348517 17T pinion is an aftermarket motor pinion built for use with the XRAY RX8 chassis, manufactured from 7075 aluminium with a hard coating to resist wear during typical on-road use.

This 17-tooth option sits within a series of pinions intended for basic gear ratio changes; altering the pinion tooth count relative to the spur gear shifts the overall ratio and changes the balance between acceleration and top speed. The range includes several tooth counts so racers can swap pinions to refine drivetrain response without other modifications.

Installation notes: verify correct mesh against the RX8 spur gear and set backlash to common on-road tolerances, recheck tooth alignment after first runs, and replace the pinion if teeth show noticeable wear. The hard-coated 7075 construction aims to combine low mass with reasonable durability for regular motor gearing maintenance.
