APE offers the strongest clutch springs available for the Hayabusa (60 psi). Originally designed for the tremendous loads of Hayabusa-powered race cars, they are the answer for clutch slippage in big bore/stroker motors as well as turbo or nitrous applications.
Most riders just use 2 or three of these springs along with their stock springs to give some added pressure.
*Comes with bolts and Retainers
