About this part

Product Details

This is a Cometic Multi-Layer Steel (MLS) head gasket, designed for your Chrysler 6.1L Gen-3 Hemi engine. It has a 4.250 inch bore and a compressed thickness of 0.036 inches. MLS gaskets are built with multiple layers of stainless steel, giving them increased strength and the ability to rebound, which helps resist corrosion. They are ideal for sealing between aluminum heads and either aluminum or cast iron blocks, handling the shearing forces that can occur between different metals.

The outer layers of this gasket are embossed and coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. Viton is chosen for its ability to perform in tough sealing environments, under various load conditions, and on different surface finishes. The center layer is stainless steel and can be varied to achieve different gasket thicknesses, like the 0.066 inch thickness of this particular gasket. These gaskets don't require any additional sealants, making installation more straightforward.
