Racing focused centre pulley with consistent engagement

The 3RACING Aluminum Center One Way Pulley Gear 3RAC-3PYW/18 targets tuners who need repeatable drivetrain response. Its aluminium construction delivers a low inertia solution that stabilises power transfer during acceleration and deceleration phases.

Performance attributes and chassis fit

Compact and precise, this pulley works with a range of common chassis arrangements and supports competitive tuning. Its one-way action helps streamline torque flow for improved traction control under race conditions.

Setup and service guidance for racers

For best results, ensure concentric mounting and accurate torque settings on all fastenings. Regular post-session checks and quick cleaning will prevent performance drift and maintain consistent lap-to-lap behaviour.

Verify shaft runout, set screw torque and lateral alignment. Minor misalignment can introduce vibration and inconsistent engagement that affect lap times.
The pulley primarily influences drivetrain feel rather than final gear ratios, but smoother engagement can make selected gearing feel more consistent under load.
Inspect alignment and fastening after practice sessions and more frequently during events. Quick checks between heats help prevent failures and keep performance stable.
