About this part

Product Details

If you're working on the 6.1L Hemi engine in your 2005-2010 Chrysler 300, this Multi-Layer Steel (MLS) head gasket from Cometic is a solid choice for sealing your cylinder heads. It's built with multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion and handle the stresses of high-output engines. This gasket is designed to provide maximum sealing performance without needing any additional sealants, making the installation process more straightforward.

The outer layers of this gasket are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is crucial for sealing effectively in demanding environments and works well with both aluminum and cast iron blocks, as well as aluminum heads. The center layer is uncoated stainless steel and can be varied in thickness; in this case, it's set to provide a compressed operating thickness of 0.036 inches, with an overall thickness of 0.066 inches and a bore size of 4.125 inches, specifically for the 6.1L Hemi application.
