XRAY RX8 Tuning Pinion 16T Hard-Coated Aluminium - Arrowmax AM-RX8-348516  [AM-RX8-348516]

Precision 16 Tooth Pinion for RX8

This 16T pinion serves as a direct replacement for the XRAY RX8 clutch and pinion assembly, shipped by Arrowmax under part number AM-RX8-348516. Built from 7075-T6 aluminium and finished with a hard coat, the gear aims to reduce surface wear while keeping rotational mass low for responsive performance.

Installation is straightforward on RX8 cars: remove the old pinion from the motor or clutch shaft, position the new 16T at the correct mesh depth, then secure using the original fastener. After fitting, rotate the drivetrain by hand and confirm mesh clearance before running.

As a tuning element, the 16T choice lets drivers tweak acceleration versus top speed in small steps; Arrowmax offers nearby tooth counts so you can fine-tune ratios for different tracks or tyre choices.
