Fit the 3RACING 3RAC-3PY/27 Aluminium Centre Pulley

The 3RACING Aluminum Center Pulley Gear T27, 3RAC-3PY/27, provides a straightforward upgrade for models that rely on a centre pulley. It helps keep torque transfer even while you push the car on mixed surfaces.

Why Aluminium Helps Performance

Aluminium offers a balance of light weight and toughness, so it resists deformation and wear better than many polymers. The 3RACING 3RAC-3PY/27 keeps tooth profiles stable, which supports consistent drivetrain feel.

Compatibility Notes and Fitting Tips

This pulley matches most 27-tooth centre setups, but confirm shaft size and mounting style before fitting. Ensure good mesh and clearances to prevent premature wear.

User Feedback

Hobbyists value this aluminium option for its durability and predictable behaviour under load, whether racing on hardpack or bashing on rougher ground.

Can I use this with a metal primary pulley?

Yes, the 3RACING 3RAC-3PY/27 pairs well with metal primaries as long as tooth counts and mesh are correct. Check alignment to avoid accelerated wear.

Will this reduce drivetrain noise?

A well-meshed aluminium pulley can run quieter than a worn plastic one, though noise also depends on bearings and overall drivetrain condition.

Is any break in required?

A short bedding period under light loads helps seating and reveals any alignment issues early. Check fasteners after the first few runs.
