K-Tech Front Fork Linear Race Springs (3624-300-80) (8.0N) (36 x 300) (Pair)

The K-Tech Front Fork Spring 8.0N is a professional-grade linear spring engineered for the highest levels of road racing.

Designed to integrate perfectly with K-Tech’s DDS (Direct Damping System) and 20IDS fork cartridges, this 8.0N rate is the ideal choice for riders who require a softer, more responsive front end to maintain mechanical grip and chassis balance.

Every spring is manufactured to DIN 2095 Grade 1 standards from premium Chrome Silicone wire. The multi-stage manufacturing process—including cold coiling, heat treating, tempering, and shot peening—guarantees that the spring rate remains perfectly consistent, lap after lap.

To ensure maximum sensitivity, each spring is ground to length and polished to minimize internal friction.
