About This Product
Wiseco 4.25-inch big bore top-end gasket kit for 2017 to 2024 M8 models running big bore cylinders. These gaskets match the oversized bore and seal the larger diameter correctly. They suit the Wiseco 576555 piston kit and most other 4.25-inch cylinder setups on the market. Do not try to seal a big bore motor with standard gaskets. Fit this set during your next top-end service.
Manufacturer part number: WW6984.
