Main Shaft Optimised for Sakura Ultimate

The 3Racing SAK-U121A Sakura Ultimate Main Shaft is a key service part that helps improve drivetrain reliability. This M5 x 30 shaft is made with precision to suit the Sakura Ultimate chassis and keep your setup running smoothly across different tracks.

Built for Endurance and Stability

Engineered from quality components, the 3Racing main shaft offers enhanced durability for frequent use. Its robust profile reduces flex and helps maintain consistent drivetrain behaviour under load.

Straightforward Installation and Better Control

Made for direct fit into Sakura Ultimate assemblies, the main shaft's exact dimensions make swapping straightforward. The correct fit reduces drivetrain lash and contributes to steadier handling through corners.

Can I reuse my existing bearings with this shaft?

In most cases existing bearings will work, provided they are in good condition and match the shaft dimensions. Replace any worn bearings for best results.

Does the shaft need a break-in period?

A brief run-in at moderate power helps seating of mating parts. After that, inspect for tightness and recheck assemblies before full-power use.

Will this improve lap consistency?

By reducing drivetrain play and offering stable rotation, the shaft can contribute to more predictable handling and steadier lap times when combined with a well-tuned setup.

Any fitment tips for installation?

Ensure all mating surfaces are clean, check alignment, and tighten fasteners progressively to avoid binding. Verify the shaft rotates freely after installation.
