    Description

    High Performance Gasket. The Mr. Gasket MLS Head Gasket; 4.080-Inch Bore/0.051-Inch Thick is engineered to provide a superior seal between the engine block and cylinder head. Designed to withstand extreme cylinder pressures in high compression, supercharged, and turbocharged applications, it ensures a reliable combustion seal for performance engines.

    Construction and Performance. This head gasket is made from three layers of premium grade stainless steel with precision laser cutting for enhanced accuracy and durability. It features optimized embossment sealing to handle extreme pressures and a proprietary polymer coating that enhances fluid sealing while allowing for a surface finish tolerance up to 60Ra, twice as rough as typical MLS gaskets. The coating also provides a smooth, textured finish that resists stress and distortion, contributing to gasket stability.

    Installation. The gasket installs directly onto compatible GM LS engines without any modifications or drilling required. It fits precisely to OEM specifications, making installation straightforward for experienced mechanics familiar with engine rebuilds and gasket replacement.

    Warranty and Application. This gasket comes with a limited lifetime warranty, ensuring long-term performance and durability. It is a direct replacement for the 2007-2017 6.0L Sierra 3500 HD engines.
