About this part

Product Details

If you're rebuilding the top end of your Harley-Davidson Big Twin engine, getting the right gasket is crucial for a solid seal. This Cometic copper base gasket is designed to fit 3 5/8 inch bore applications, providing a reliable seal for your engine's cylinders.

Made with a copper base, these gaskets offer good thermal conductivity and conformability, which helps create a tight seal even with the heat and pressure inside your engine. At .005 inches thick, they are a standard replacement size, suitable for many rebuilds where precise deck height adjustments aren't the primary goal. This pack comes with two gaskets, so you'll have one for each cylinder.
