Heavy Duty Clutch Spring Kit Suzuki Hayabusa (99-07)

Description

Upgrade your Hayabusa’s clutch with Brock’s Heavy Duty Clutch Spring Kit—built to handle the punishment of high-power drag-style launches. Manufactured from valve-spring quality steel, each spring is shot-peened and stress-relieved to withstand extreme heat and abuse. Guaranteed for millions of trouble-free, sag-free cycles, these springs deliver the reliability serious riders demand.

By increasing spring pressure, this kit helps extend clutch life, improve ETs, and add MPH—especially beneficial for riders over 170 lb. Designed as a direct replacement for stock springs and ultra-mod spacers, these springs offer stronger, more consistent engagement without sacrificing rideability.
