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

Overview of alloy pulley covers for RX8

The Arrowmax AM-RX8-345800 pulley cover set is designed as a 7075 alloy swap-in for the XRAY RX8 plastic pulley collars. Machined from 7075 aluminium, these covers increase rigidity at the pulley mounting points and help retain consistent belt alignment during both setup adjustments and on-track loads.

The parts are made to fit the RX8 kit configuration and replace the standard plastic pieces without altering the gearbox arrangement. Installation involves partial disassembly of the rear pulley area and reusing original fasteners if applicable, with a subsequent pulley runout check recommended.

From a setup point of view, the alloy covers give firmer support to the pulley shaft which can reduce small belt deflection and aid repeatable belt tension settings. They are a practical, cost effective metal upgrade for hobbyists seeking an alternative to kit plastics.
