Precision forged Wiseco clutch baskets have greater strength due to feature aligned grain flow Forged from lightweight, high-strength, certified aerospace grade aluminum alloy Wiseco's CNC machining process produces each clutch basket dimensionally the same as the next Weight-reducing relief cuts on the outside diameter of the clutch basket reduces rotational mass, which lowers the centrifugal force acting on the clutch basket and increasing overall acceleration of the engine Large oiling holes in the clutch basket tangs increase lubrication, reduce heat build-up and reduce weight Hard anodized for an ultra tough, abrasive-resistant surface ensures a long life of smooth clutch operation through the elimination of wear on the sides of the clutch basket tabs A Teflon coating seals the clutch basket to create a near frictionless surface for the clutch disks to glide upon Supplied with high-quality fasteners complete with pre-applied thread locker for a secure grip during assembly
