XRAY 345889-O Graphite 29T Front Low Friction Pulley  [XR-345889-O]

Performance upgrade for belt-driven RC cars

The XRAY 345889-O Low Friction Composite Side Belt Pulley brings a practical drivetrain upgrade for hobbyists. Molded from a graphite composite, this 29T pulley balances wear resistance with reduced drag to help your car run cleaner and more consistent laps.

Precision graphite composite construction

Manufactured from a tuned graphite composite, the pulley reduces surface friction for smoother belt tracking and less energy loss. The material and molding process deliver a consistent part that helps maintain steady drivetrain efficiency under load.

Fitment and straightforward installation

The 345889-O mounts on the centre shaft of most side belt-driven models and is driven by the side belt for dependable torque transfer. The pulley ships without the protective cover, which is available separately as the Composite Belt Pulley Cover Set #345800-O.

Practical choice for drivetrain tuning

If you are refining gear mesh and drivetrain losses, the XRAY 345889-O is a useful component to consider. Its low friction profile and rugged composite build make it a straightforward upgrade for competitive and club-level racers alike.
