Cometic Primary Gasket Single Pack - Harley Panhead, Shovelhead & Evolution Big Twin
About Cometic
Cometic Gasket manufactures multi-layer steel head gaskets and complete gasket kits in Concord, Ohio. On a built V-twin running higher compression or a big-bore kit, the MLS head gasket is what keeps the top end sealed — which is why Cometic is the default spec on so many engine builds.
This Cometic primary gasket provides a reliable seal for your Harley-Davidson Panhead, Shovelhead, or Evolution Big Twin engine. Engineered to OEM specifications, it ensures your primary cover stays sealed against the engine case, preventing leaks and maintaining optimal performance. This is a single gasket, perfect for one service.
