About this part

Product Details

If you're working on a 2005-2010 Chrysler 300 with the 6.1L HEMI engine, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of your build. It's specifically designed for a 4.100 inch bore and has a compressed thickness of 0.075 inches, making it a solid choice for high-output applications where a reliable seal is critical.

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and the ability to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating ensures a strong seal against aluminum heads and blocks, even with the potential for shearing forces between different metals. Because they are designed for maximum sealing performance, these gaskets typically do not require any additional sealants.
