About Cometic

Provided in a practical 10-pack, these gaskets are perfect for professional shops, fleet maintenance, or riders who prefer to keep essential service parts readily available.

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?
