High Performance Graphite Component

The XRAY 345888-G low friction side belt pulley is a 28-tooth graphite composite unit developed for the RX8E 2023 chassis. It emphasises a lower rotating weight while maintaining the rigidity required for competitive running.

Performance Benefits

Graphite composite delivers good wear resistance and low mass, which can improve drivetrain smoothness. The XRAY 345888-G pulley is designed to help reduce energy loss across the belt drive, aiding acceleration consistency.

Fitting Guidance

Fit on the outside of the centre shaft where the side belt engages. The pulley ships without a cover; use the #345800-G Composite Belt Pulley Cover Set if you need enclosure and extra protection.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is a belt cover necessary with this pulley?

A cover is not required for basic operation but using the #345800-G cover improves protection from debris and helps maintain belt life on dusty tracks.

Does installing this change recommended belt tension?

No major change is needed; set belt tension to the RX8E 2023 specification. Verify alignment after fitting to avoid side loading on the pulley teeth.

Can I polish or treat the pulley surface?

Light cleaning and removal of mould lines is fine, but avoid aggressive machining or solvents that could weaken the composite. Keep the contact area free of grit.
