XRAY RX8 18T Composite Side Pulley Rear Upgrade for RX8 - Arrowmax AM-RX8-345838  [AM-RX8-345838]

Composite side pulley tailored for RX8 drivetrains

The Arrowmax AM-RX8-345838 composite side belt pulley is manufactured as a replacement part for the XRAY RX8 chassis. Built from 7075 aluminium and finished with a hard coating, the design emphasises long service life and easy cleaning rather than cosmetic styling. Side slots in the pulley body let grit and belt dust escape, helping reduce build-up along the belt route.

Functionally the pulley operates as the rear-side belt drive element and is intended for a direct like-for-like replacement of RX8 rear pulleys. The hard-coated 7075 construction increases surface wear resistance versus plain aluminium, aiming to keep belt seating steady during practice and setup work.

Experienced hobby technicians will find installation simple: remove the original rear side pulley, check the belt and mating parts for wear, fit the Arrowmax pulley to the same shaft position, then verify belt alignment and tension. No special electronics or drivetrain changes are necessary; it fits into the RX8 belt layout and supports normal drivetrain tuning like tension adjustments and break-in checks.

This product is offered as an RC model accessory only and is described here strictly as a component for RX8 vehicles.
