Why is this head gasket thicker than the original?

This gasket is intentionally manufactured thicker than the stock OE gasket. This can be helpful to achieve the correct piston-to-valve clearance, especially if your cylinder head or block has been machined or if you are using different pistons during your engine rebuild.

What else might I need when installing this head gasket?

When replacing a head gasket, it's standard practice to also replace the head bolts and ensure the cylinder head and engine block surfaces are perfectly clean and flat. Always refer to the manufacturer's installation instructions for a complete list of recommended procedures and parts.

Does this gasket come with installation instructions?

While this gasket is designed as a direct OE replacement, it is recommended to consult the Fleece Performance installation guide or a service manual for the correct torque specifications and sequence to ensure proper sealing and engine longevity.

About this part

Product Details

This is a thick, OE-style replacement head gasket for your 2003-2007 Dodge Ram 2500 or 3500 equipped with the 5.9L Cummins engine. When you're rebuilding the top end of your engine, a solid head gasket is crucial for sealing the combustion chambers and coolant passages. This gasket is designed to meet or exceed the original specifications, ensuring a proper seal and reliable performance for your truck.

Fleece Performance chose a thicker gasket design here, which can be beneficial in certain engine rebuilds. This often helps to achieve the correct piston-to-valve clearance if you've had machine work done on the cylinder head or block, or if you're using slightly different pistons. It's a well-built part made to withstand the high pressures and temperatures found in a Cummins diesel engine, helping to prevent leaks and maintain compression.

When installing a head gasket, it's always important to follow the manufacturer's torque sequence and specifications precisely. This ensures the gasket seals evenly and prevents premature failure. Make sure your cylinder head and block surfaces are clean and flat before installation.
