1957-1985 Harley-Davidson Sportster Series Cylinder Base - Front & Rear

This interface base gasket is a direct-fit replacement designed to provide a secure seal at the engine block interface. It effectively prevents oil leaks and maintains proper compression by creating a durable barrier between the cylinder and the crankcase. The specialized interface material ensures a reliable fit that conforms to the sealing surfaces of the Ironhead engine.

This gasket fits Harley-Davidson models manufactured between 1957 and 1985 equipped with the Ironhead engine.
