The top end piston bearings from Wiseco are high-quality bearings made from the highest standards to increase durability and performance.

Wiseco™ started in 1940 on the East Side of Cleveland, Ohio when Clyde Wiseman began making pistons for himself and some of his friends. After almost a century in the business, Wiseco™ has been identified as a piston manufacturer, but they didn't stop there. Wiseco™ went on to making a plethora of innovative motorsports equipment from clutch covers to valve kits, including Wiseco Top End Bearing, that will not have you questioning the quality or care that was put in to making them.

Precision engineering and the use of first class materials guarantee that they meet or exceed O.E. standards, Top End Gasket KitIncludes head, base and exhaust gasket
