Race Oriented T12 Pulley from 3Racing

The 3Racing Aluminum Center Pulley Gear T12, model number 3RAC-3PY/12, is manufactured with race use in mind to provide consistent tooth engagement and repeatable performance. Aluminium construction offers a firmer interface for aggressive setups while lowering the chance of deformation under thermal or mechanical stress.

Precision Fit and Engagement

Accurate machining ensures the pulley preserves intended clearances and tooth profile alignment, helping reduce drivetrain lash and irregular backlash. This promotes smoother torque transmission and more predictable throttle response during tuning and race conditions.

Install and Tuning Considerations

For competitive setups, verify concentricity and shaft alignment during installation, and use controlled tightening to maintain balance. The 3Racing Aluminum Center Pulley Gear T12 integrates well into tuned drivetrains where consistent mesh and reduced play are priorities.

What alignment checks should be performed after fitting?

Check axial runout and lateral play, confirm the pulley sits parallel to mating components, and spin the assembly to verify smooth engagement under light load.

Are there recommended lubrication practices for race use?

Use a light, compatible lubricant on sliding interfaces only where specified; avoid heavy greases that can attract debris and affect tooth contact in race conditions.

How does aluminium compare to other materials for competitive setups?

Aluminium offers a balance of stiffness and light weight suitable for tuned drivetrains, but confirm that mating parts and fastenings are matched to handle increased loads.
