About this part

Product Details

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's built for high-output engines like the Chrysler 6.4L Apache Gen-3 Hemi, fitting a range of vehicles including the Dodge Challenger, Ram 2500, and Jeep Grand Cherokee. This gasket is designed to provide maximum sealing performance without needing additional sealants, making it a solid choice for your rebuild.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound and resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This makes it suitable for use with both aluminum and cast iron blocks, as it can withstand the shearing forces created when different metals are joined. The center layer is stainless steel, and its thickness can be varied to achieve different compressed operating thicknesses, like the 0.075 inches on this particular gasket, which results in a 0.036 inch compressed thickness.
