KPMI® clutch springs are designed to thrive in a high stress environment where they are subjected to elevated temps, as well as high impact and shock loads. They resist taking a set, and have excellent fatigue life. They are designed to work with OEM clutch components. Manufactured from high quality chrome silicon wire, they are designed to supply 20% more plate load than stock springs.
Note: The powdercoat finish applied to these clutch springs makes them a slightly larger diameter than stock, depending on your spring cups, you may need to remove some or all of the finish to fit these springs
