Cometic 01-06 GM 6.6L Duramax 104.14mm Bore .056in MLS-5 Head Gasket Left

When you're rebuilding the top end of your GM 6.6L Duramax diesel, getting the head gaskets sealed right is critical for performance and longevity. This Cometic MLS-5 head gasket is built for that job, designed to handle the high output and demanding conditions these engines can face. It's a multi-layer steel gasket that offers a strong, reliable seal without needing any extra sealants.

This gasket uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes, making it suitable for both aluminum and cast iron blocks. The specific thickness of this gasket is 0.056 inches, with a bore size of 4.100 inches, and it's designed for the left-hand side of the engine. This construction helps it withstand the forces created when mating different block materials, like aluminum heads to cast iron blocks.

This gasket fits a wide range of GM trucks and SUVs, including models like the Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, and Chevrolet Express 2500. It's a well-built component for anyone looking to ensure a solid seal during engine work.
