Precision One-Way Centre Pulley for Tuned Drivetrains

The 3Racing Aluminum Center One Way Pulley Gear T17 is intended for racers and tuners seeking predictable drivetrain behaviour. Machined aluminium construction gives stable geometry and resistance to deformation under load.

Performance Advantages for Competitive Use

The one-way mechanism provides directional slip characteristics that help retain forward inertia and smooth torque transfer during throttle transitions. This contributes to repeatable lap-to-lap performance when combined with correct gearing and setup.

Fitment, Maintenance and Integration

Designed for compatibility with common centre pulley layouts, this part is straightforward to integrate into racing builds. Routine inspection of bearings and mating surfaces is recommended to preserve optimal operation in race conditions.

What measurements should tuners check before fitting?

Confirm bore size, overall diameter and offset relative to your current centre pulley. Also verify shaft retention method to ensure secure mounting for race use.

How does this pulley affect drivetrain tuning?

By lowering internal friction and offering controlled one-way action, it can improve throttle response and midcorner exit stability, allowing finer setup adjustments elsewhere in the drivetrain and suspension.

Recommended maintenance for race reliability?

Inspect bearings and mating surfaces pre and post event, clean out debris, and replace any worn bearings. Ensure secure fastening and check for play after initial running-in.
