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 primary housing case O-ring gasket is engineered to provide a superior seal for Evo Big Twin and Twin Cam V-twin engines. It prevents fluid weeping and leakage from the primary case, ensuring your drivetrain remains clean and functional.
A reliable seal is critical for preventing messy and potentially damaging leaks from your primary. This Cometic primary housing case O-ring gasket is built to the demanding specifications of Evo Big Twin and Twin Cam V-twin engines. Utilizing advanced gasket materials and manufacturing processes, it offers a direct replacement for your stock gasket, designed to handle the heat and vibration of high-performance Harley and Indian Motorcycle applications.
When it's time to service your primary, don't overlook the importance of a quality gasket. This Cometic primary housing case O-ring gasket offers a robust solution for maintaining the integrity of your V-twin's drivetrain. Its direct-fit design makes installation straightforward, allowing you to confidently seal up your primary and get back on the road without worrying about leaks.
Does this gasket fit my Twin Cam Harley?
Yes, this Cometic gasket is specifically designed for Twin Cam primary housings. If you have an older Evo Big Twin, it also fits those applications. For Milwaukee-Eight engines, you'll need a different gasket.
Is this a direct bolt-on replacement for my primary case gasket?
Yes, this Cometic gasket is a direct replacement. Installation typically involves removing the old gasket, thoroughly cleaning the mating surfaces, and then installing the new Cometic gasket with your stock fasteners.
Will this gasket work with Indian Motorcycle V-twin engines?
This gasket is designed for V-twin engines with Evo Big Twin and Twin Cam architecture, which can include certain Indian Motorcycle models. Always confirm compatibility with your specific model and engine family.

keeps the oil on the right side
Easy to install. Good quality and price. Does what it is supposed to do
Very good quality/value for the price, I would buy them again.
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.
easy to replace just like oem
