About this part

Product Details

Cometic Gasket is known for making well-built sealing components for a wide range of engines. This Multi-Layer Steel (MLS) head gasket is specifically designed for the Chrysler 6.1L Gen-3 Hemi engine, featuring a 4.250-inch bore and a compressed thickness of .080 inches. It's built to handle the demands of high-output applications, ensuring a solid seal between your cylinder heads and block.

This gasket uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes. This construction means the gasket requires no additional sealants and is suitable for use with both aluminum and cast iron blocks, effectively managing the stresses that can occur between dissimilar metals. The center layer is stainless steel and can be varied in thickness to meet specific build requirements.

This gasket is a direct fit for the 2005-2010 Chrysler 300, as well as several Dodge and Jeep models with the 6.1L Gen-3 Hemi engine. If you're rebuilding the top end of one of these vehicles and need a reliable seal for a performance application, this Cometic gasket is a solid option.
