3RACING 3RAC-3PYW/21 Aluminium Centre One Way Pulley Gear

The 3RACING 3RAC-3PYW/21 is a centre one way pulley machined from aluminium to offer a blend of lightness and robustness. It is intended as a direct upgrade path for drivers wanting steadier drivetrain behaviour and clearer power transfer.

Cleaner Power Transfer

This pulley reduces unwanted drivetrain play and helps the car apply power more smoothly, which benefits traction out of corners. Aluminium construction holds up under regular use while keeping spinning mass low for improved response. Fitment normally requires only routine checks and minor setup tweaks.

General Compatibility

Although specific vehicle fitment is not listed, this pulley is commonly used in 1/10 scale platforms and suits hobbyists who service or upgrade their drivetrains. Expect more consistent throttle feel and easier control at race pace.
