About this part

Product Details

If you're rebuilding the top end of your 5.7L Gen-3 Hemi engine, especially one that's seeing higher output, a solid set of head gaskets is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of modern performance engines. It's designed to seal effectively without needing any extra sealants, making the installation process more straightforward.

Cometic builds these gaskets with multiple layers of stainless steel, which gives them strength and the ability to rebound, helping them resist 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 is ideal whether you're mating aluminum heads to an aluminum block or aluminum heads to a cast iron block, as it can manage the shearing forces that can occur between different metals. The center layer is stainless steel, and its thickness can be varied to achieve different compressed operating thicknesses, like the .098 inches on this particular gasket, which has a 4.100-inch bore to match your engine's needs.

This gasket fits a wide range of Chrysler, Dodge, Jeep, and Ram vehicles from the mid-2000s to mid-2010s. Make sure to check the fitment details to confirm it's the right choice for your specific application.
