A solid seal at the cylinder base is critical for engine integrity and performance. These James Gaskets cylinder head base gaskets feature a durable metal construction with an integrated bead seal, providing a robust and reliable barrier for your V-twin engine. This 2-pack includes both front and rear gaskets, ready for a complete engine rebuild.

The integrated bead seal further improves sealing effectiveness by concentrating pressure at critical points. This 2-pack provides both the front and rear gaskets needed for a comprehensive bottom-end refresh or engine rebuild.
