Cometic's MLS head gaskets feature advanced construction with embossed spring steel layers that meet the demands of high-performance V-Twin engines. The center shim layer can be varied to accommodate specific thickness requirements, while the embossed outer surfaces create a heavy-duty seal that resists corrosion and maintains strong torque retention across extreme temperature ranges.
