These gaskets were proudly manufactured in the USA, with materials from the USA by Cleveland Gasket®. They 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.
These gaskets have been tested both on the street and at the Bonneville Salt Flats, and have been proven to be superior to anything available in fit or function. 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. These 500 unit rocker box gaskets replace Triumph part # 70-9511 or E9511, and are .032" thick.
