K-Tech Front Fork Linear Race Springs (3624-300-95) (9.5N) (36 x 300) (Pair)

The K-Tech Front Fork Spring 9.5N is a professional-grade linear spring engineered to meet the extreme demands of track-day enthusiasts and professional racers.

Designed to work seamlessly with K-Tech’s DDS (Direct Damping System) and 20IDS fork cartridges, this 9.5N rate offers the structural integrity required to maintain chassis geometry during the most intense braking phases.

Manufactured from the highest grade Chrome Silicone wire, each spring undergoes a meticulous production process: cold coiling, heat treating, tempering, and shot peening. This ensures that the 9.5N rate remains consistent and won't "sack" or fatigue under racing conditions.

To maximize performance, every spring is polished to reduce internal friction, delivering a smoother fork action and superior front-tire feedback.
