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

Rear axle pulley for RX8

This Arrowmax pulley is made for XRAY RX8 chassis owners seeking a direct replacement or upgrade for the rear solid axle pulley. Machined from 7075 T6 aluminum and finished with a hard coating, the part focuses on durability and weight savings while keeping drivetrain geometry unchanged.

Design details include 48 teeth, precision CNC machining, and side holes that help shed grit and debris that accumulate between pulley faces and belts. The hard-coated surface resists wear from belt contact, helping maintain consistent mesh and reducing the need for frequent replacement.

Installation is straightforward for users familiar with RX8 rear-end servicing: remove the original rear pulley from the solid axle, inspect bearings and retaining hardware, replace with this unit, and check belt alignment and tension before test running. No modifications to the chassis are required when used as a like-for-like replacement.

As a direct-fit rear pulley for the RX8, this Arrowmax part offers a balance of stiffness and lightness, with a hard-coated finish and drainage holes to support consistent belt performance during track use.
