Racing focused steering upgrade

The 3Racing Sakura D4 King Pin 5.8mm Ball Stud SAK-D422 is developed with competitive setup work in mind. Its tighter tolerances help eliminate slack in the steering train, improving repeatability during aggressive driving.

Setup oriented performance gains

When fine tuning rack and king pin geometry, the 5.8mm ball stud from 3Racing provides a stable pivot with minimal compliance. That stability aids precise toe and ackerman adjustments critical for race tuning.

Durability for circuit use

Specified for frequent track use, the SAK-D422 offers long service intervals under race conditions. Use as part of a measured upgrade path to balance chassis response and steering feedback for qualifying and race runs.

How does this affect steering geometry tuning?

Reducing joint compliance with this stud stabilises steering reference points, making small toe and ackerman changes more predictable. Recheck geometry after installation to confirm settings.

Is this suitable for high downforce setups?

Yes. The SAK-D422 holds steering integrity under increased load, which helps maintain consistent contact patch behavior when aerodynamic or mechanical grip is high.

Recommended inspection interval at events?

Check steering joints between practice and timed runs, and after any incident. Quick head checks and torque confirmation keep the part race ready.
