Heavy Duty Clutch Spring Kit GSX-R1000 (05-06), GSX-S1000 (18-20), and Katana (2020)

Description

Brock’s Heavy Duty Clutch Spring Kit is built to outperform standard OEM springs. Manufactured from valve-spring quality steel, each spring is shot-peened and stress-relieved to withstand the extreme heat and abuse of high-power drag-style launches. Guaranteed for millions of trouble-free, sag-free cycles, these springs deliver consistent, repeatable performance every time you launch.

By increasing spring pressure by approximately 25%, this kit helps extend clutch life, eliminate “spongy” lever feel, and maximize power transfer to the track—translating into better ETs and higher MPH. Heavier riders (170+ lb.) will see even greater performance gains.
