3RACING 3RAC-3PY/21 Aluminium Center Pulley Gear - Performance Upgrade  [3RAC-3PY/21]

Upgrade your driveline with the 3RACING 3RAC-3PY/21 pulley

The 3RACING Aluminum Center Pulley Gear T21, model number 3RAC-3PY/21, offers a metal alternative to standard plastic pulleys to improve wear resistance and maintain smooth power delivery. Its aluminium construction keeps weight modest while adding toughness where it matters.

Aluminium benefits for consistent drive

Aluminium holds its shape under load and heat, which helps preserve accurate gear engagement and reduces the chance of slippage or rapid wear. That reliability is useful for both casual running and more focused track use.

Compatibility and fitting guidance

This pulley is compatible with many common 1/10 scale platforms and fits without major chassis changes. When fitting, confirm the bore and set screw positions, then test for smooth rotation before full use.
