Upgrade your GSX-R1000’s clutch performance with Brock’s Heavy Duty Clutch Spring Kit. Built from valve-spring quality steel, each spring is shot-peened and stress-relieved to handle the extreme heat and abuse of high-horsepower, drag-style launches. Unlike typical OEM springs, these are engineered to deliver millions of trouble-free, sag-free cycles for consistent, repeatable performance.
By increasing clutch spring pressure by approximately 25%, this kit helps extend clutch life, eliminate “spongy” lever feel, and put more power to the ground. Riders over 170 lb. will especially notice improved ETs and MPH gains.
