Lightweight Graphite 20T Pulley for Competitive Use

The XRAY 345820-G Graphite 20T Belt Pulley targets drivers looking to refine drivetrain behaviour. CNC-precise molding from a graphite composite gives a compact, stiff pulley that helps keep rotating mass low.

Purpose Built for Rear Belt Drive Systems

This pulley is intended for the main layshaft to drive the rear belt with minimal resistance, striking a useful balance between durability and smooth operation. Note that the pulley cover is sold separately and the compatible option is the #345800-G Composite Belt Pulley Cover Set - Graphite.

Great for Upgrades and Routine Rebuilds

Matched to RX8E 2023 specifications, the part is a practical swap when refreshing wear items or when fine tuning for lap time consistency on sealed or carpet surfaces.
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.

Can I use this pulley on conversions or custom layouts?

The pulley is made for RX8E 2023 specifications; custom installations may work but you should check layshaft spacing and belt alignment before fitting.

What benefits does graphite bring over plastic?

Graphite offers a lower mass and higher stiffness than many plastics, which can reduce rotational inertia and improve drivetrain feel under acceleration.

Do I need special tools to fit the pulley?

Installation normally requires basic RC tools such as hex keys and a torque friendly driver. Ensure set screws are tightened to spec and belts are correctly tensioned.
