Improve Drivetrain Stability with the 3RACING T40

The 3RACING T40 Aluminium Differential Pulley Gear, model 3RAC-3PY/40, is a straightforward upgrade for hobbyists focused on reliable drivetrain performance. Its aluminium build aims to combine strength with modest weight savings to help maintain consistent gear contact under load.

Durability for Club and Trail Use

From 3RACING, the T40 pulley is intended to withstand normal club use and trail running. Aluminium construction reduces long-term wear compared with softer materials, keeping drivetrain action smoother over extended sessions.

Fitment Flexibility and Easy Swap

The pulley works with numerous common differential setups and is designed for straightforward replacement. Hobbyists can usually swap in the 3RACING T40 with basic tools and minimal chassis changes, making it a practical upgrade for many cars.

Do I need to change my diff oil after fitting the pulley?

It is good practice to check and refresh diff oil after any drivetrain work. This ensures internal parts run smoothly with the new pulley installed.

Will this pulley reduce drivetrain noise?

Aluminium pulleys can help stabilise gear mesh and may reduce certain noises caused by worn or flexible plastic parts, but noise also depends on overall drivetrain condition.

Is any break-in required for aluminium gears?

A short running period under gentle load is advisable to confirm correct fit and to allow mating surfaces to settle. Inspect fasteners after the first few sessions.
