Racing Focused T13 One Way Pulley

The 3Racing T13 centre one way pulley 3RAC-3PYW/13 is developed for competitive builders seeking tighter drivetrain control and repeatable engagement. Precision machined aluminium reduces compliance and improves consistency under high load.

Setup and Compatibility for Tuners

This pulley is suitable for a range of tuned chassis where centre one way systems are used; confirming spline, bore and tooth profile is essential before fitment. The alloy construction helps preserve alignment and reduces wear on mating components.

Tuning Benefits and Reliability

With a one-way mechanism tuned for efficient power transfer, the T13 assists with throttle response and exit traction. The robust aluminium body provides long service intervals when paired with routine inspection and proper installation practices.

What measurements should I verify for fitment?

Verify bore diameter, spline count and pulley tooth pitch against your chassis drawings; mismatches can lead to premature wear or assembly issues.

How does aluminium affect drivetrain tuning?

Aluminium reduces part flex and maintains consistent geometry, which helps tuning settings remain stable session to session, improving predictability at the limit.

Any service recommendations for race use?

Inspect for burrs and wear after every race meeting, clean mating surfaces and confirm fastener torque to avoid play that degrades lap time consistency.
