Cometic Harley-Davidson 2017-22 Milwaukee 8, All Fl w/Primary, 4.320in,.030inMls

This is a Cometic MLS (Multi-Layer Steel) head gasket specifically made for 2017-2022 Harley-Davidson Milwaukee 8 engines with a primary cover. It's designed with a 4.320-inch bore and a thickness of 0.030 inches, intended for rebuilds where precise sealing is critical. MLS gaskets are well-built for high-performance applications because they use multiple layers of steel with a specialized coating. This construction helps them conform to sealing surfaces, providing a strong seal that can handle the high pressures and temperatures found in modern V-twin engines. The 0.030-inch thickness is a common choice for engine builders looking for a slight adjustment in compression ratio during a rebuild.
