Upgrade your drivetrain with the XRAY 345938 18T pulley

Built for racers and serious hobbyists, the XRAY 345938 - 18T Aluminum Side Belt Pulley Set pairs precise CNC machining with race grade materials. Made from Swiss 7075 T6 aluminum, it keeps mass low while standing up to track abuse. The hardcoated surface adds extra abrasion resistance for longer service life.

Precision machining for reduced rotating mass

The XRAY 18T side belt pulley mounts on the main layshaft to drive the side belt with minimal friction. Strategic lightening lowers rotating inertia yet retains structural strength, helping the motor and drivetrain respond cleaner during acceleration and cornering. This factory pre-assembled unit is ready to fit, cutting installation time.

Key advantages of the XRAY 18T pulley

  • Material: Swiss 7075 T6 aluminum for a strong but light component.
  • Durability: Hardcoated finish improves wear resistance under load.
  • Design: Lightened profile to reduce rotating mass without sacrificing stiffness.
  • Assembly: Supplied factory pre-assembled for straightforward installation.
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.

Which XRAY chassis will accept this pulley?

The pulley is compatible with XRAY models that use the same main layshaft and side belt configuration. Check your chassis parts list to confirm fitment before ordering.

Can I trim or modify the pulley to save more weight?

The pulley is already lightened by design; further machining is not recommended as it may unbalance the part or reduce strength. Use the supplied unit as intended for best reliability.

How should I maintain the hardcoat finish?

Keep the pulley free of grit and check for scoring after heavy use. Clean with a soft brush and mild solvent, and replace the pulley if deep wear or deformation appears.
