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 starter shaft housing gasket is a direct replacement for Panhead, Shovelhead, and Evolution Big Twin engines. It's specifically designed to seal the shaft housing, preventing oil seepage at the starter mounting point. Maintaining this seal is crucial for the longevity and cleanliness of your classic V-twin.

Working fine was for my brother's bike
Works Fine at a lower cost
I usually have an OEM from Harley Davidson, I have used this twice on my 04 Electraglide, no leaks or issues. At a much lower price.
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.
A good buy
The gasket fit nicely and no leaks so far . The fitment was spot on .
There is nothing on them indicating they are actually Cometic gaskets. Are they Substitutes?
