Cometic 1984+ Harley-Davidson Stock Big Twin .005 Copper Base Gasket - 2 Pack

When you're rebuilding the top end of your 1984 and later Harley-Davidson Big Twin, getting the sealing surfaces just right is critical. These Cometic copper base gaskets are designed to provide a reliable seal for your engine's cylinders.

Made with a copper base, these gaskets offer good thermal conductivity and conformability, which helps them seal effectively even with the heat and pressure found in a V-twin engine. The .005 inch thickness is a stock dimension, meaning it's intended to replace your original gasket without altering compression ratios or piston-to-valve clearance. This pack comes with two gaskets, so you'll have what you need for a typical rebuild.
