XRAY RX8 Front 28T Composite-Style Pulley Hard-Coated - Arrowmax AM-RX8-345888  [AM-RX8-345888]

Front 28T pulley for RX8 applications

The Arrowmax AM-RX8-345888 front side belt pulley is a direct replacement option for the XRAY RX8 series, intended for maintenance and front-end rebuilds. It is CNC machined from 7075 T6 aluminium with a hard-coated finish to resist belt friction wear while preserving low inertia for responsive drivetrain behaviour.

Drilled cutouts in the side profile allow debris to escape and reduce the chance of material building at the belt contact area, which eases cleaning and upkeep. In its role as a front pulley it influences belt tensioning and can be used when refreshing front drivetrain components on RX8 chassis layouts.

Fitting advice: treat as an RX8 spare part, fit using factory mounting hardware, verify belt tracking and tension after installation, and inspect the pulley seating prior to the initial run.
