Cometic Chrysler 6.1L Gen-3 Hemi .075in MLS Cylinder Head Gasket-4.185in Bore-Aluminum Sleeved Block

If you're working on the 6.1L Gen-3 Hemi engine in your 2005-2010 Chrysler 300, this Multi-Layer Steel (MLS) head gasket from Cometic is built to handle high output. It's designed with a 4.185-inch bore and a compressed thickness of 0.036 inches, making it suitable for aluminum sleeved blocks.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it 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 coating ensures a strong seal even under demanding conditions and works well with different block and head materials, like aluminum to aluminum or aluminum to cast iron. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.075 inches this gasket offers.

Because these MLS gaskets are well-built and don't require sealants, they offer maximum sealing performance for engines that push more power.
