Common questions

Will this fit my Sportster?

No, this is a Big Twin primary housing gasket. Sportster models use a different gasket part number, so please verify fitment for your specific bike.

Is this an OEM gasket or aftermarket?

James Gaskets manufactures this to OEM specifications as a direct aftermarket replacement. It is not packaged as an original Harley-Davidson or Indian Motorcycle part.

Do I need any special tools to install this?

Standard socket and wrench tools are typically sufficient. Always remove the primary cover, clean the mating surface, and follow your service manual's torque specifications when installing the new gasket.
