Looking for a reliable head gasket solution for your 6.7L Cummins under high-performance conditions? Our 6.7L Fire Ring Gasket is designed to handle extreme cylinder pressures, providing a superior seal that protects against leaks and failure - especially important as horsepower climbs beyond 800 HP. Maximize your 6.7L Cummins' reliability and performance with our Fire Ring Gasket solution.

Backed by years of engineering experience, it's the trusted choice for racers, heavy haulers, and diesel enthusiasts alike.

Features and Benefits:

• Superior Seal under high boost and extreme pressures.
• Reduced Risk of Failure thanks to consistent clamp load and radiused grooves.
• Perfect for High-Power Builds, particularly those pushing beyond 800 HP.
• Proven Durability in severe-duty performance applications.

Details:

• Sold As: Each
• Universal: No
• Vehicle Type: Truck
• Liter: 6.7L
• Fuel Type: Diesel
• Valve: 24-Valve
• Thickness: .066 Inch (1.75 mm)
• Wire O.D.: 4.560 Inch (using .105 Inch wire)
• Groove Radius: .017 Inch - .018 Inch if cutting grooves in the head or block

Fitment Notes:

• Fitment: 2007.5-2018 Dodge/Ram 6.7L Cummins 24-Valve engines requiring a 0.020 Inch-over fire-ring head gasket.
• Must use high-strength studs to achieve proper clamp load, particularly with our competition gasket.

Installation Notes:

• Ensure the head is within .003 Inch end-to-end for optimal sealing.
• Best practice: Machine both the head and block for perfect flatness.
• If you do not surface the block, be sure to use an axe sharpening stone with 320 or finer to clean up the deck surface.
• Engines 800 HP: cut grooves in the head
• Be sure to use 625 studs
• Always use a .120 Inch radiused cutter for precise groove formation.
• Initial Torque: 130 ft-lbs at startup.
• Hot Retorque: After reaching operating temperature, retorque while the engine is still warm.
• Check Valve Lash: Each retorque further compresses the gasket, reducing valve lash - re-adjust as needed.
• Final Check: Retorque at least once more before applying full load or RPM.
• Apply a liberal amount of lube to the nut, washer, and threads so that all studs see a consistent clamp load.
• Never exceed manufacturer torque limits - fasteners at full torque store significant potential energy.
