Race-Ready 3RACING Aluminum Differential Pulley Gear T33

The 3RACING Aluminum Differential Pulley Gear T33, catalog 3RAC-3PY/33, is a compact upgrade aimed at reducing rotating mass while keeping robust service life. The aluminium pulley offers a firmer feel through the drivetrain for drivers who demand predictable behaviour on corner exits.

Performance Advantages

Replacing a stock plastic pulley with aluminum cuts inertial load and improves rotational stability. The material stands up to repeated runs and helps maintain gear geometry under load, which supports consistent lap times and handling feel.

Installation and Typical Applications

This pulley fits many pulley-driven differentials used in 1/10 scale models. It is a suitable upgrade for competitive club racers and serious hobbyists who want a straightforward way to improve drivetrain efficiency.

What checks should I make before fitting?

Verify bore diameter and spline compatibility with your differential output shaft and confirm there is sufficient clearance for the new pulley.

Can I run this with higher torque motors?

The pulley improves durability over plastic alternatives, but ensure adjacent drivetrain parts are rated for increased torque to avoid transferring load to weaker components.

How do I maintain optimal performance?

Keep gear teeth clean, use appropriate grease on mating surfaces, and inspect the pulley and fasteners regularly for play or fretting.
