XRAY RX8 Rear Pulley 48T Hard-Coated 7075 - Arrowmax AM-RX8-345148  [AM-RX8-345148]

Rear pulley solution for RX8

The Arrowmax AM-RX8-345148 rear pulley is tailored for XRAY RX8 drivers who want a durable, lightweight replacement. CNC machined from 7075 T6 aluminum and treated with a hard coating, the design preserves factory drivetrain geometry while improving surface longevity.

The pulley features 48 teeth, tight machining tolerances, and side cutouts that expel dirt and grit that can lodge between the belt and pulley faces. The treated surface helps reduce wear from belt contact and keeps engagement consistent lap after lap.

Installation is straightforward for anyone familiar with RX8 rear-end work: remove the original pulley, check bearings and fasteners, swap in the Arrowmax AM-RX8-345148, and recheck belt tracking and tension before running. No chassis alterations are required for standard replacement use.

As a direct-fit option, this Arrowmax pulley gives RX8 racers a good mix of reduced mass and robust surface protection to help keep belt performance steady.
