Upgrade your classic Suzuki GSX-R1100 or Katana with Brock’s Extra Heavy Duty Clutch Spring Kit—built to withstand the demands of high-power drag-style launches. Unlike typical industry springs, these are manufactured from valve-spring quality steel, then shot-peened and stress-relieved to handle extreme heat, stress, and abuse. Guaranteed for millions of trouble-free, sag-free cycles, they deliver consistent performance pass after pass.
By increasing lever pressure by approximately 30%, this kit provides the extra clamping force needed to extend clutch life, eliminate “spongy” lever feel, and put more power to the pavement—helping riders improve both ET and MPH.
