XRAY RX8 Front 28T Side Pulley Lightweight Alloy - Arrowmax AM-RX8-345888  [AM-RX8-345888]

RX8 Front 28T side pulley overview

This Arrowmax AM-RX8-345888 front side belt pulley is supplied as a direct replacement for the XRAY RX8 series and is intended for routine maintenance or setup changes. The component is CNC machined from 7075 T6 aluminium and finished with a hard coating to withstand belt wear while keeping mass low for improved drivetrain response.

The pulley profile includes drilled lightening holes that help eject debris and reduce material trapped at the belt interface, making cleaning and service intervals easier. As the front pulley it contributes to belt tension balance and can be swapped during front drivetrain refreshes on RX8 layouts.

Installation notes: treat this as an RC-scale spare for the RX8 chassis, install using the original factory hardware, confirm belt alignment and tension after fitting, and verify correct seating before the first run.
