Technical Brief for 3Racing 3RAC-3PY/15 Centre Pulley

The 3Racing Aluminum Center Pulley Gear T15, model 3RAC-3PY/15, is intended as a performance-oriented replacement part for systems using a 15-tooth centre pulley. Constructed from aluminium, it supports consistent tooth geometry and predictable engagement under load, which assists setup work and repeatable tuning in competitive environments.

Material and Drivetrain Impact

Aluminium reduces rotating inertia relative to denser materials, aiding transient response and allowing tighter control over acceleration characteristics. The material also offers stable surface behaviour for repeated track use.

Application Notes for Tuners

Use this pulley when refining gear mesh or replacing worn components during setup cycles. As with any drivetrain change, validate spline and bore compatibility, confirm mesh, and test under controlled conditions before race use.

How does this pulley affect drivetrain tuning?

By lowering rotating mass and providing stable tooth geometry, the pulley helps deliver more consistent clutching and acceleration characteristics, which is useful when tuning throttle response.

What checks are essential after fitting?

Confirm spline alignment, verify bore seating, and ensure mesh is even across the tooth flank. Reassess after a few runs to detect any movement or wear.

Is this pulley suited for competitive use?

It is designed to meet the needs of racers seeking repeatable drivetrain behaviour; pair with proper setup and regular inspection to maintain performance.
