These gaskets were proudly manufactured in the USA, with materials from the USA by Cleveland Gasket®. These are aluminum core with a nitrile rubber bonded to both sides. This AFM gasket material has excellent temperature resistance, torque retention, and compression.

No sealant of any type is needed, and due to the high rate of recovery when disassembled, in most cases the gaskets can be reused. There will be no pink, green, or blue gasket material hanging over the edge of your rocker box. There will be no drama or discussion about which sealant to use and how to apply it.
