About this part

Product Details

If you're rebuilding the top end of your 2005-2010 Chrysler 300 with the 6.1L Hemi, a solid set of head gaskets is crucial for a leak-free seal. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of these powerful engines.

Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and different surface finishes, ensuring a tight seal between your aluminum heads and block. The center layer is stainless steel and can be varied in thickness; this particular gasket is 0.060 inches thick with a 4.055-inch bore, designed for specific engine builds. These MLS gaskets don't require sealants, making installation more straightforward.
