Cometic GM 6.6L Duramax Diesel 01-06 4.100 inch Bore .045 inch MLS Left Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring a Viton rubber coating on the outer layers. This construction is designed to handle the high output of modern engines, providing a strong seal without needing additional sealants. It's suitable for combinations of aluminum heads with aluminum blocks or cast iron blocks, as it can manage the shearing forces that arise from different metals working together.

The multiple stainless steel layers give this gasket increased strength and the ability to rebound, which helps resist corrosion. The Viton coating on the outer layers is a heat-resistant material, capable of withstanding temperatures up to 482°F (250°C), making it well-suited for demanding sealing environments. The center shim layer is uncoated stainless steel and can be varied to achieve different compressed thicknesses, with this specific gasket measuring 0.045 inches when compressed. This is the left-side gasket for your engine.

This gasket fits a wide range of GM 6.6L Duramax diesel trucks, including models like the Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD from 2001 through 2016. It's a solid option when you need a reliable seal for your engine's top end.
