Overview of the 3Racing 3RAC-3PY/38 38T Pulley

The 3Racing 38T aluminium differential pulley gear, model 3RAC-3PY/38, is designed to increase drivetrain robustness while maintaining reliable tooth engagement. The aluminium build offers improved resistance to wear compared with softer materials, and the precise 38T geometry supports consistent power transfer. This makes it a sensible upgrade for both competitive layouts and regular hobby use.

Why Choose This Pulley

Material: Aluminium for enhanced durability under repeated use.
Tooth Count: 38T teeth for accurate and consistent meshing with mating components.
Compatibility: Suits a variety of RC differentials that use a 38 tooth pulley, enabling adaptable fitment.
Functionality: Helps the drivetrain maintain steady operation and reduces variability in power delivery.

How do I check if this will fit my model?

Verify the tooth count and mounting style of your current pulley. If your model lists a 38T differential pulley, the 3Racing 3RAC-3PY/38 should be a match.

Will swapping to aluminium affect drivetrain noise?

Metal pulleys can change the sound profile slightly due to material properties, but they usually offer more consistent meshing which can reduce irregular noises from wear.

Can I use this in daily practice sessions?

Yes, the aluminium pulley is suitable for regular practice and club racing, offering improved wear resistance for routine running.
