Cometic 2014+ Harley-Davidson Twin Cooled 4.125 .036 MLS Head Gasket

This is a Multi-Layer Steel (MLS) head gasket from Cometic, specifically made for 2014 and newer Harley-Davidson Twin Cooled engines with a 4.125 inch bore. It's designed to be .036 inches thick, which is a common thickness for rebuilding or modifying these popular V-twin engines.

MLS head gaskets are well-built with multiple layers of stainless steel, often with a special coating on each layer. This construction helps them handle the high pressures and temperatures found in modern motorcycle engines, especially those that are liquid-cooled like the Twin Cooled Harley-Davidsons. The multiple layers allow the gasket to conform to the surfaces of the cylinder head and the engine block, creating a strong seal that resists leaks even under demanding conditions. This particular gasket is a direct fit for the specified Harley-Davidson models, meaning it's made to the exact dimensions needed for installation without modification.
