Setup-focused 18T pulley for tuning

The 3Racing Sakura Ultimate 18T Center Pulley Set, model SAK-U422, is supplied to enable precise 2.2 gear ratio adjustments on the Sakura Ultimate chassis. It is matched to the stock 18T2014 configuration and is suitable for drivers who adjust drivetrain ratios to achieve specific lap time characteristics.

Optimise drivetrain behaviour for competition

Engineered with attention to tooth profile and engagement consistency, this 18T pulley supports predictable gear mesh and repeatable performance under load. The 2.2 ratio helps refine throttle control and traction management, making it a useful component when iterating setup for qualifying and race conditions.

How does the 2.2 ratio influence gearing strategy?

A 2.2 centre ratio shifts torque distribution to favour smoother midrange response. In practice, use it to reduce wheelspin on corner exit and to fine tune acceleration without altering motor timing or battery load drastically.

What should I verify during setup changes?

Verify gear mesh, backlash and alignment after installing the pulley. Confirm slipper/clutch settings and test under consistent track conditions to record measurable changes before further adjustments.

Is this pulley compatible with tuning packages?

Yes, the SAK-U422 integrates with common Sakura Ultimate tuning parts. When combining with aftermarket items, ensure clearances and shaft alignment remain correct to maintain reliability during competitive runs.
