Engineered Spring for Sakura Ultimate Chassis Tuning

The 3Racing SAK-U314/WH/775 Sakura Ultimate White Spring is manufactured to deliver repeatable spring rate and minimal hysteresis for competitive tuning. The 15x7.75 dimensions are matched to Sakura Ultimate shock geometry to support consistent rebound and compression response.

Technical Advantages for Racers

Precision wound to control linearity across the travel, this white spring enables targeted setup changes without large downstream effects to balance. The finish also aids rapid identification during setup work between runs.

Application and Setup Notes

  • Improved Handling: Provides a predictable rate curve that tightens turn-in and stabilises mid-corner behaviour for lap time improvements.
  • Durable Material: Specified for longevity to resist fatigue across frequent race weekends and maintain rate integrity.
  • Customisable Setup: Compatible with typical Sakura Ultimate damper configurations to fine-tune compression and rebound independently.

What test procedure is recommended when installing these springs?

Fit the spring with nominal preload, run two to three laps to observe dynamic behaviour, then log changes in droop and rebound before incremental adjustments to damper valving.

How should I document setup changes using this spring?

Record spring preload, damper oil weight, and shock mounting positions. Compare lap times and handling notes to isolate the effect of the 3Racing SAK-U314/WH/775 spring.

Any compatibility cautions for tuning shops?

Confirm shock length and spring seat diameter before fitment. While optimised for Sakura Ultimate, ensure shock hardware is standard to avoid binding or incorrect preload.
