WW6984 4.25" big bore gasket kit

If you are running a high-performance Milwaukee-Eight with a 4.25-inch big bore kit, this Wiseco gasket set is a necessity for your next top-end service. Specifically engineered to handle the increased cylinder diameter, these gaskets provide a reliable seal for 2017 to 2024 M8 models equipped with big bore cylinders. While they are the perfect companion for the Wiseco 576555 piston set, they are also compatible with most other 4.25-inch cylinder setups on the market. Don't risk your engine's compression with standard gaskets; use this purpose-built kit to ensure leak-free performance on your built motor.
