XRAY RX8 29T Front Side Belt Pulley Upgrade - Arrowmax AM-RX8-345889  [AM-RX8-345889]

Front Alloy Side Pulley for RX8

This Arrowmax AM-RX8-345889 pulley is an RC-scale front side belt pulley made for the XRAY RX8 platform. CNC machined from 7075 T6 aluminum and treated with a hard coating, the part balances low mass with surface durability compared with untreated alloys. Venting holes around the pulley flange help shed grit and keep the belt contact area clear, which supports steady belt engagement along the RX8 belt route.

Intended role and tuning notes: fit this pulley in the front belt location on the RX8 chassis to replace the stock front pulley. Its hardened finish and close CNC tolerances help the pulley hold concentricity under load, aiding consistent belt tension during setup and tuning without altering belt geometry.

Installation: the pulley is supplied as a single front-belt component for XRAY RX8 installations; confirm fitment with your RX8 mounting points and existing hardware before installation. Regular inspection and cleaning of the side holes will reduce debris buildup when running on dusty surfaces.
