Cometic Harley-Davidson Twin Cam .018 MLS Head Gasket

The Cometic C9721-018 is a Multi-Layer Steel (MLS) head gasket designed for Harley-Davidson Twin Cam engines. It features a compressed thickness of .018 inches and a round bore shape with a 3.875-inch bore size, constructed with 2 layers.

The gasket's center or shim layer is uncoated stainless steel, allowing for varied thickness accommodations. The outer layers are embossed and coated with Viton, enabling them to withstand demanding sealing environments, load conditions, and surface finishes. This construction promotes an even torque load and reduces bore distortion for improved piston ring seal and power. Made in the USA.
