Product Details

If you're working on the right side cylinder head for your GM 6.6L Duramax diesel, this Multi-Layer Steel (MLS) head gasket from Cometic is a solid option. It’s built for the 2001-2016 model years, covering popular engines like the LB7, LLY, LBZ, and LMM. This gasket is designed to handle the high output these engines are known for, providing a strong seal without needing any extra sealants.

Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes. The compressed thickness is 0.051 inches, and it's made for a 4.100-inch bore. This construction makes it suitable for mating aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces between different metals.

This gasket is a direct replacement for many Chevrolet and GMC trucks, including models like the Silverado HD, Sierra HD, Express, and Savana vans. It's a well-built component designed for reliable performance in demanding diesel applications.
