Wiseco forged clutch components have greater strength due to "feature aligned grain flow". Compared to castings or products machined from billet, Wiseco forged clutch components are lighter and still have increased mechanical properties resulting in higher strength, ductility, and resistance to impact and fatigue. Hard anodized and Teflon coated for a long life of smooth clutch operation through the elimination of wear on contact surfaces. Specifically designed to capitalize on detailed features that can only be produced by the precision forging process. Now with a Lifetime Guarantee against notching or breaking!
