Get a robust, leak-free seal on the 2007.5–2018 6.7L Cummins with the Hamilton Cams Fire Ring Head Gasket Standard .046″. Standard .046″ thickness (1.25 mm) with a 4.560″ wire diameter (.105″ wire) for added stability in high-performance builds under high boost.
Why Choose the Hamilton Cams 6.7L Standard Fire Ring Head Gasket?
- High-performance sealing – For extreme horsepower and boost levels.
- Standard thickness – .046″ (1.25 mm) for stock-height builds.
- Maximized clamp load – A design that minimizes the risk of head-gasket failure.
- Precision machined – For a consistent fit and performance.
- Engineered and tested by Hamilton – Backed by diesel performance expertise.
Fitment Notes
- Engines under 800 HP: cut grooves in either the head or the block.
- Engines over 800 HP: run a high tensile fastener like the ARP 625.
- Studs are a must — this competition gasket requires studs to achieve the clamp load needed for higher horsepower.
Installation Highlights
Have the head and block machined for flatness before installation, and use a radiused cutter for all groove work. Apply a generous amount of lube to the nut, washer and threads for even torque, and never exceed manufacturer torque limits. Aim for 130 ft-lb on initial startup, retorque hot at operating temperature, readjust valve lash, and retorque at least once more before full load or high RPM.
