3RACING 3RAC-3PYW/21 Performance One Way Pulley

The 3RACING 3RAC-3PYW/21 is a performance-oriented centre one way pulley designed to sharpen drivetrain response in competitive 1/10 scale cars. Constructed in aluminium to reduce rotating mass, it helps drivers achieve cleaner torque application and more consistent lap times.

Setup and Tuning Focus

Installers should check gear mesh, bearing play and slipper settings when fitting this pulley since its reduced inertia changes transient behaviour. The component is sized for straightforward integration into common racing drivetrains and supports precise trimming of throttle characteristics.

Application and Race Use

Ideal for racers who modify drivetrains for better corner exits and repeatable launches. Verify dimensional compatibility with your chassis before installation and consider minor slipper or diff adjustments to capitalise on the pulley benefits.

What setup changes improve lap time with this pulley?

Reducing slipper engagement slightly and tightening gear mesh can exploit the lower inertia for crisper drive. Test with short runs and log lap consistency.

Is this pulley suitable for high bite surfaces?

Yes, on high traction tracks the pulley helps deliver power cleanly; pair it with tuned slipper settings to avoid wheel hop on exit.

Any precautions for competitive use?

Confirm bore and bearing fits, inspect regularly for wear, and carry a spare pulley at events to minimise downtime.
