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 Twin Cam transmission gasket is engineered for reliable, leak-free performance on both Evolution and Twin Cam V-twin engines. This 10-pack is an ideal solution for shops, multi-bike owners, or riders who prefer to keep spares on hand for future service.

Comprehensive kit with everything needed to re-seal a trans. The only reason I didn't give 5 stars is because it comes with paper gaskets instead of the foam/metal ones. No leaks for now. We will see how long they last.
