3RACING Aluminum Differential Pulley Gear T33 for Cleaner Power Delivery

The 3RACING Aluminum Differential Pulley Gear T33, reference 3RAC-3PY/33, gives modelers a compact way to reduce drivetrain drag and improve throttle response. Its aluminium build lowers mass on spinning parts, helping to smooth acceleration and reduce strain on nearby components.

Why Choose an Aluminum Pulley

Aluminum offers a useful mix of lightness and durability for everyday club racing and recreational runs. The metal construction holds up better to heat and abrasion compared with stock plastic pieces, making it a practical upgrade for regular use.

Fitment Notes and Typical Uses

This pulley is aimed at setups using pulley-style differentials and works well in tuned 1/10 scale cars. It is a solid choice for drivers who want improved drivetrain consistency without major modifications.

Can this pulley be used on vintage kits?

It can work on older kits that share the same pulley pitch and bore, but confirm dimensions before attempting to fit it.

Will it change gearing or top speed?

The pulley maintains the same tooth count, so gearing stays the same; reductions in rotating mass can slightly improve acceleration and transient response.

Is any break-in required after install?

A short break-in under light running conditions helps mating surfaces bed in; inspect for play and re-torque fittings after initial runs.
