About this part

Product Details

This is a Cometic MLS-5 head gasket for the 6.1L Hemi engine found in your 2005-2010 Chrysler 300, and also fits other Mopar vehicles like the Dodge Challenger, Charger, Magnum, and Jeep Grand Cherokee. Head gaskets are critical for sealing the combustion chamber, oil passages, and coolant passages between your engine block and cylinder heads. When you're pushing higher cylinder pressures or dealing with extreme temperatures, a well-built gasket is essential to keep everything running smoothly.

Cometic builds these gaskets with multiple layers of stainless steel, which helps them rebound and resist corrosion. This multi-layer steel (MLS) construction is designed to handle the increased demands of modern, high-output engines. The gasket measures .040 inches thick and has a 4.185-inch bore, making it a precise fit for the 6.1L Hemi. These gaskets are proudly made in the USA using materials sourced domestically.
