Hayabusa clutch cushion replacement springs provide increased pressure for higher MPH and less clutch wear. DO NOT use with ultra mod spacers in early Hayabusa applications. These springs replace stock springs and ultra mod spacers in Hayabusa clutch cushion. They are incompatible with the stock Hayabusa clutch mod or ultra mod without the Hayabusa clutch cushion. They offer severe lever pressure for serious drag and land speed racing use. Installer is responsible for non-coil-bind assembly. Clutch Slave Cylinder Support is also required in (99-07) Hayabusa applications.
