3RACING 3RAC-3PYW/21 Aluminum Center One Way Pulley

The 3RACING 3RAC-3PYW/21 is a practical drivetrain upgrade that swaps in a lightweight aluminum one way pulley to improve power delivery in many RC setups. Built to balance light weight and durability, it helps tighten throttle response while keeping overall mass low.

Improved Response and Handling

This pulley is aimed at hobbyists seeking crisper acceleration and more predictable handling on paved surfaces. The aluminum construction reduces rotational inertia, helping the car react quicker to inputs while remaining robust enough for regular club use. Installation is straightforward and typically requires minimal adjustments to existing layouts.

Fitment and Typical Applications

Exact fit depends on your vehicle, so check your driveline dimensions before fitting. The design is commonly compatible with many 1/10 scale cars and is a sensible choice for racers and weekend tuners who want smoother power transfer and more consistent corner exits.
