Say good bye to the typical industry clutch spring! Manufactured from valve spring quality material, shot-peened and stress relieved specifically to handle the heat and stress of high power drag-style sport bike launches. Brock's new springs are guaranteed for millions of trouble-free (and SAG-free!) cycles.
We spared no expense to produce a spring for your late model rocket... neither should you. Increased spring pressure prolongs clutch life and can help increase E.T. and MPH. These gains can be multiplied if the rider is over 170 lb.
