Common questions
Will these gaskets fit my Milwaukee-Eight (M8) engine?
No, these Cometic gaskets are specifically engineered for Twin Cam engines only. Milwaukee-Eight owners will need a different Cometic part number for their application.
Why are these gaskets sold in 10-packs?
The 10-pack quantity is designed to cater to professional shops, riders who maintain multiple bikes, or individuals who prefer to keep spares on hand for future service needs.
Are these the same as the genuine Harley-Davidson gaskets?
