Product Description
Push your ZX-10R’s clutch performance to the limit with Brock’s Extra Heavy Duty Clutch Spring Kit. Built from valve-spring quality steel, these springs are shot-peened and stress-relieved to handle the punishing heat and torque of high-horsepower drag-style launches. Designed for consistency and durability, they are guaranteed for millions of trouble-free, sag-free cycles—far beyond what typical industry springs can deliver.
By increasing lever pressure approximately 20%, this kit provides longer clutch life, firmer engagement, and more MPH, all while reducing the dreaded “spongy” lever feel. With included shims and adjustable tops, you can fine-tune clutch pressure to match your setup.
