Cometic Primary Housing Gasket Inner Spacer/Seal - Harley Evo Big Twin & Twin Cam
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.
The Cometic Primary Housing Gasket serves as an inner spacer and seal, critical for a tight interface between your primary housing and engine case. This gasket is engineered to prevent oil leakage and maintain proper primary compression on your V-twin.
