Drivetrain Tuning with the 3RACING T40 Pulley

The 3RACING T40 Aluminium Differential Pulley Gear, model 3RAC-3PY/40, is suitable for drivers refining drivetrain characteristics for race conditions. Its aluminium construction supports consistent gear engagement, aiding predictable torque transfer during lap-to-lap setups.

Track-Oriented Durability and Response

Engineered by 3RACING for hop-up applications, the T40 pulley provides a durable interface in the drivetrain where precise engagement matters. Reduced material compliance versus softer materials helps preserve gear geometry under load, which assists with repeatable handling and lap consistency.

Integration and Setup Notes

Designed for compatibility with common differential formats, the pulley allows quick incorporation into tuning routines. When installing the 3RACING T40, verify shaft alignment and final fastener torque, then confirm diff preload and mesh as part of the setup checklist.

How does the T40 influence diff behaviour on corner exit?

By stabilising gear engagement, the T40 can reduce transient lash and promote smoother torque transfer on corner exit, aiding traction consistency in high load transitions.

What setup checks are recommended after fitting?

After fitting, confirm axial play, diff preload and mesh, then run a short test session to verify no binding. Re-check fasteners and bearing alignment before final tuning.

Is this suitable for aggressive tuning changes?

The T40 supports more aggressive setup work where durable, stable pulleys are needed. However, ensure other drivetrain components are matched to the increased demands to avoid creating a new failure point.
