High-Performance Head Gasket. The Mr. Gasket MLS Head Gasket with a 4.080-inch bore and 0.051-inch thickness is designed to provide a superior seal between the engine block and cylinder head. This is essential for maintaining combustion pressure and preventing leaks. Specifically engineered for GM LS engines, it improves reliability under the extreme conditions commonly found in high compression, supercharged, and turbocharged applications.

Construction and Appearance. Crafted from three layers of premium-grade stainless steel using advanced laser cutting technology, this head gasket features embossed sealing areas that optimize radius and reduce stress points. A proprietary polymer coating ensures an effective seal of engine coolant and oil passages, while the gasket’s finish supports sealing on surface finishes rougher than those typically suited for standard MLS gaskets.

Installation. Installation requires standard mechanical skills and no drilling or modifications are necessary. It is designed to fit directly in place of OEM gaskets, ensuring a straightforward upgrade for compatible engines.

Warranty. The product includes a limited lifetime warranty, demonstrating confidence in its durability and performance.

Application. Specifically designed to fit 2008-2013 6.0L Yukon engines.
