Precision machined centre pulley from 3Racing

The 3Racing Aluminum Center Pulley Gear T13 - 3RAC-3PY/13 is built for hobbyists looking for tight tolerances and dependable operation in their RC drivetrains. This aluminium pulley is a straightforward upgrade to help maximise drivetrain efficiency while keeping weight low and strength high for demanding runs.

Smoother power transfer on track

Swapping a standard plastic centre pulley for this aluminium unit can reduce flex and improve power transmission. The T13 pulley helps maintain consistent gear engagement and cuts down on wear, making it a practical choice for weekend racers and club drivers alike.

Aluminium advantages explained

Aluminium offers better heat dissipation and greater durability compared with many plastic alternatives, which is important during extended running. The precision machining of the T13 gear delivers a secure fit to reduce slippage and support consistent performance.

Will the 3RAC-3PY/13 fit my model without modification?

Check your model's parts list and shaft dimensions. Many models accept the T13 pulley but some will need a spacer or minor shimming to achieve the correct mesh.

How does aluminium affect drivetrain noise?

Aluminium can change the sound compared with plastic, often producing a crisper tone. Proper mesh and lubrication will help keep noise and wear to a minimum.

Any routine checks after fitting the pulley?

After installation verify gear mesh, check for play on the shaft, and run a short test to confirm no binding. Recheck after a few runs to ensure secure fitment.
