About This Product
When you are building a massive 4.500" bore Milwaukee-Eight, you need the Extreme Sealing Technology found in this Cometic EST top end gasket kit. The kit features .040" Multi-Layer Steel head gaskets and .020" Single-Layer Steel base and rocker cover gaskets with a high-temperature Viton coating. It is a complete kit for a full top-end rebuild, including all required gaskets, seals, and o-rings. This kit fits 2018 to 2024 Softail and 2017 to 2024 Touring and Trike models. Please note that these gaskets are only embossed for the bore and oil drain, meaning the heads must be plugged or welded in all cases. It is a heavy-duty sealing solution for the most extreme M8 performance builds.
Manufacturer part number: C10225.
