Restore and upgrade your Hayabusa’s clutch performance with Brock’s Clutch Cushion Replacement Spring Kit. Designed as a direct replacement for stock springs and Ultra Mod spacers, this kit increases spring pressure for stronger clamping force—delivering higher MPH, quicker acceleration, and longer clutch life.
Manufactured from valve-spring quality steel, each spring is shot-peened and stress-relieved to handle the extreme heat and stress of drag-style launches. Engineered for millions of trouble-free cycles, these springs provide consistent performance and eliminate the dreaded “spongy” lever feel.
