3Racing 3RAC-3PY/15 Aluminium Centre Pulley T15 Upgrade  [3RAC-3PY/15]

Race-Ready Centre Pulley 3Racing 3RAC-3PY/15

The 3Racing Aluminum Center Pulley Gear T15, model 3RAC-3PY/15, is designed as a sturdy upgrade for RC vehicles that use a 15-tooth centre pulley. Built from aluminium, it gives an upgraded feel over many stock components while keeping consistent tooth geometry for reliable engagement.

Benefits of an Aluminium Pulley

Aluminium offers a useful balance of stiffness and lightness, which can reduce rotational inertia and make throttle response feel more immediate. It also resists corrosion so the pulley keeps performing after repeated use.

Practical Uses and Installation Notes

Ideal for replacing worn plastic pulleys or for fine-tuning drivetrain behaviour. Confirm fitment and check alignment during installation to maximise life and minimise wear on mating parts.
