XRAY RX8 Rear Solid Axle Pulley 48T Compatible Upgrade - Arrowmax AM-RX8-345148  [AM-RX8-345148]

Rear axle pulley designed for RX8

The Arrowmax AM-RX8-345148 rear pulley is specified for XRAY RX8 vehicles needing a robust, low-mass replacement. Machined from 7075 T6 aluminium and treated with a hard coat, it aims to extend service life at the belt contact points while keeping factory geometry intact.

The pulley carries 48 teeth and is produced to tight CNC tolerances. Side relief holes are included to evacuate dirt and debris that can gather between pulley flanges and the belt. The hard-coated surface reduces abrasion and helps maintain steady engagement over many runs.

Installation follows the standard RX8 rear-end routine: remove the original pulley, inspect bearings and securing hardware, fit the Arrowmax AM-RX8-345148, then check belt tracking and tension before a full test. No chassis modifications are required for standard fitment.

As a direct-fit option for the RX8, the Arrowmax AM-RX8-345148 combines reduced rotating weight with a wear-resistant finish and drainage features to support reliable belt performance on circuits.
