XRAY RX8 7075 Aluminium Pulley Cover Set - Arrowmax AM-RX8-345800  [AM-RX8-345800]

7075 aluminium pulley cover overview for RX8

The Arrowmax AM-RX8-345800 pulley cover set is a metal replacement made for the XRAY RX8 chassis, intended to swap in for the original plastic pulley collars. Manufactured from 7075 aluminium, the covers stiffen the pulley mounting points and help keep belt alignment consistent under both setup adjustments and track load.

These covers are specifically sized for the RX8 kit layout and replace the stock plastic parts without changing gearbox geometry. Fitting the parts requires basic disassembly of the rear pulley area and the reuse of original fasteners where appropriate, with a follow up check of pulley runout after installation.

From a tuning perspective, the aluminium covers offer firmer support around the pulley shaft to reduce minor belt movement and help maintain repeatable belt tension during setup changes. They provide a durable, cost effective metal alternative to the kit collars for racers wanting improved consistency.
