Cometic Cummins 5.9L ISB CR .067in MLX Cylinder 4.100in Bore Head Gasket

When you're rebuilding the top end of your Cummins 5.9L ISB CR, a solid head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and block.

Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. This construction means the gasket doesn't require any additional sealants, making installation more straightforward. The center layer is stainless steel, and its thickness can be varied to achieve specific compressed operating thicknesses, like the 0.098 inches you get with this gasket. This design is effective for sealing between aluminum heads and either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals.

This particular gasket is designed for a 4.100-inch bore and has a compressed thickness of 0.098 inches, with an uncompressed thickness of 0.067 inches. It's a well-built component that fits right into your 2003-2008 Dodge Ram 2500 or 2003-2007 Dodge Ram 3500.
