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 Piston 12:1 83.50mm +.50, that will not have you questioning the quality or care that was put in to making them.
