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 Twin Cam transmission gasket is a critical component for sealing your V-twin's transmission case, effectively preventing oil leaks. Supplied in a practical 10-pack, these gaskets are perfect for professional shops, fleet maintenance, or individual riders who prefer to keep essential service parts stocked. Engineered to meet OEM specifications, they ensure a secure and reliable seal.

A mediocre gasket
I didn’t use this gasket after removing the derby and seeing the Harley gasket that I removed. No comparison in quality. I ended up going to the local dealer and bought an O.E. gasket.

There is nothing on them indicating they are actually Cometic gaskets. Are they Substitutes?
