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 inspection and derby cover gasket with an integral O-ring seal is designed for Harley Evo Big Twin engines. It's sold in convenient 10-packs, perfect for shops or multi-bike owners.

A leaky derby cover is a common sight on older V-twins, but it doesn't have to be. This Cometic 10-pack of inspection and derby cover gaskets for Evo Big Twin engines features an integral O-ring for a superior, leak-free seal. Having a stock of these means you're always ready for fluid changes or clutch inspections, ensuring your primary stays sealed tight.

Maintain Your Primary System
Every time you pull the derby cover for a fluid check or clutch adjustment, that gasket needs to be replaced to maintain a proper seal. This Cometic 10-pack ensures you have plenty of fresh gaskets on hand, allowing you to perform routine maintenance with confidence. Keep your Evo Big Twin's primary system sealed and performing as it should.

Good gasket, I like these because they are the same thickness as factory, and do not change the end play on the cam and breather

Decent gasket. Sticks out of the nosecone cover a bit at the top as it doesn't follow the nose cone shape precisely. Seals well.
