XRAY RX8 7075 Composite Belt Pulley Cover Set by Arrowmax AM-RX8-345800  [AM-RX8-345800]

Composite pulley cover for RX8

This Arrowmax AM-RX8-345800 pulley cover set is an RC-scale replacement designed for the XRAY RX8 chassis, intended to swap in for the stock plastic pulley collars. Machined from 7075 aluminium, the covers increase rigidity at the pulley mounting points and help maintain consistent belt alignment under setup and track loads.

Fitment is intended specifically for the RX8 kit configuration as described by the source, replacing the standard plastic parts without altering gearbox layout. Installation requires basic disassembly of the rear pulley area and reuse of the original fasteners where applicable, taking care to check pulley runout after installation.

From a tuning perspective, these aluminium covers provide firmer support for the pulley shaft which can reduce minor belt deflection and contribute to repeatable belt tension settings during setup changes. They are a low-cost, durable option for hobbyists seeking a metal alternative to the kit plastic collars.
