About this part

Product Details

Cometic Gasket is a well-known name for creating solid sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example of their work. It's built for a range of GM Duramax diesel engines, including popular models like the LB7, LLY, LBZ, LMM, LGH, and LML. If you're rebuilding the top end of your Duramax, this gasket is designed to provide a reliable seal between the cylinder head and the engine block.

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 with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in harsh sealing environments. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, like the .053 inch thickness of this particular gasket. This multi-layer design means it doesn't require any additional sealants, making installation more straightforward, and it's suitable for use with both aluminum and cast iron blocks.

This gasket is a solid option for many GM trucks and vans from the mid-2000s to mid-2010s, including models like the Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, and Chevrolet Express 2500. Ensure you check the full fitment list to confirm it's the right part for your specific vehicle.
