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.
Keep your Twin Cam engine sealed tight with this 10-pack of Cometic rocker box assembly gaskets. Designed with an ARM support O-ring, these gaskets provide a reliable seal against oil seepage in your V-twin.

When you're wrenching on a Twin Cam, a reliable rocker box gasket is non-negotiable. These Cometic rocker box assembly gaskets are engineered to provide a robust, leak-free seal, keeping your top end buttoned up. Sold in a convenient 10-pack, they're perfect for shops, multi-bike owners, or anyone who values having spares on hand for routine maintenance or unexpected rebuilds.

Whether you're doing a cam swap, a top-end refresh, or just chasing down a persistent leak, these gaskets offer peace of mind and help keep your Harley-Davidson Twin Cam running strong.
