Wiseco’s pistons outgun cast and Hypereutectic pistons, giving you stronger pistons and tighter tolerances than any other part in your engine, with less internal and external machining. Our advanced forging process and extensive heat-treat and finishing process assure you of the performance and reliability you demand from your engine.

Please keep in mind that Wiseco only makes 9.0:1 "off the shelf" pistons now for the 7M.
