This Multi-Layer Steel (MLS) head gasket from Cometic is designed specifically for your 2005-2010 Chrysler 300, as well as other compatible Dodge and Jeep models with the 6.1L Gen-3 Hemi. It's built to handle the demands of high-output engines, ensuring reliable performance and preventing leaks between your cylinder head and block.
