3Racing Sakura Ultimate Steering Knuckle Technical Overview

The 3Racing Sakura Ultimate Steering Knuckle - SAK-U105 is engineered to deliver tightened steering geometry and repeatable performance under race loads. Its design supports consistent toe and ackerman behaviour during aggressive driving and rapid direction changes.

Material and Performance Considerations

Manufactured to meet competitive demands, the SAK-U105 offers enhanced resistance to flex at critical steering attachment points. This stabilising effect reduces setup drift and allows drivers to retain chosen steering characteristics over longer runs.

Fitment, Setup and Tuning Notes

Fitment is aligned with the Sakura Ultimate mounting architecture; installation should use correct torque settings and confirmed ball stud orientation. When upgrading, re-evaluate steering geometry, servo centring and linkage lengths to extract maximum performance gains from the part.

How does the SAK-U105 affect ackerman and steering ratio?

The knuckle preserves original geometry but reduces component flex, which can make ackerman behaviour feel more pronounced. Minor tie rod adjustments may be required to restore preferred steering balance.

Are there recommended supporting upgrades?

For race use, pair the SAK-U105 with fresh tie rods, low friction bearings and a high torque servo to capitalise on improved steering precision and to avoid other components limiting performance.

What checks should be done after initial installation?

Verify steering centring, confirm no binding through full travel, and re-torque fasteners after first runs. Record toe and camber settings to compare before and after upgrade.
