K-Tech Front Fork Linear Race Springs (3624-336-85) (8.5N) (36 x 336) (Pair)

The K-Tech Front Fork Spring 8.5N (3624-336-85) is designed for elite-level performance.

Specifically engineered for use in K-Tech’s DDS and 20IDS fork cartridges, these springs are the choice of champions in BSB, WorldSBK, and the Isle of Man TT.

At 8.5N, this rate provides a plush yet supportive feel, ideal for riders looking for maximum front-end "feel" and mechanical grip.

Manufactured to DIN 2095 Grade 1 standards, these springs are cold-coiled from premium Chrome Silicone wire. The multi-stage process of heat treating, tempering, and shot peening ensures the spring rate remains perfectly linear and never "sags," even under the extreme heat and pressure of professional racing.
