XRAY RX8 29T Composite Side Belt Pulley by Arrowmax AM-RX8-345889  [AM-RX8-345889]

Front Composite Side Belt Pulley for RX8

This Arrowmax AM-RX8-345889 pulley is an RC-scale front side belt pulley designed for the XRAY RX8 platform. Machined from 7075 T6 aluminum and finished with a hard coating, the part keeps mass low while improving wear resistance compared with untreated alloys. Side holes in the pulley allow debris to clear the contact area during running which helps maintain consistent belt engagement on the RX8 belt path.

Intended role and tuning notes: install this pulley at the front belt position on RX8 chassis to replace or upgrade the stock front pulley, where its hardened surface and CNC tolerance help maintain concentricity under load. The part is aimed at hobbyists focused on drivetrain reliability and repeatable belt tension during setup and tuning, without changing belt geometry.

Installation: the pulley is offered as a single RC component for the front belt location on the XRAY RX8; verify fitment against your RX8 front mounting points and existing hardware before fitting. Routine inspection and cleaning of the side holes will help prevent debris buildup in high-dust running environments.
