XRAY RX8 Front 29 Tooth Belt Pulley Upgrade by Arrowmax AM-RX8-345889  [AM-RX8-345889]

RX8 Front Side Pulley Overview

The Arrowmax AM-RX8-345889 is a purpose-built front side belt pulley for the XRAY RX8. Crafted from 7075 T6 aluminium with a protective hard coat, the pulley keeps weight down while improving resistance to wear versus untreated metal. Perforated side holes let loose material escape the contact area, helping the belt run cleanly along the RX8 belt path.

Role and setup notes: install this pulley at the RX8 front belt position to replace the original part. Its hardened surface finish and tight CNC tolerances help the part remain concentric under load, which supports repeatable belt tensioning during tuning sessions without changing the overall belt geometry.

Fitting guidance: supplied as a single item for the front belt location on XRAY RX8 layouts. Verify the pulley dimensions against your RX8 mounting and hardware before fitting. Periodic cleaning of the side holes will keep debris from collecting in dusty track or trail conditions.
