The Hamilton Cams .080" Fire Ring Gasket is designed for 1989-1998 Dodge Cummins 5.9L engines to ensure a stronger seal under high boost. With its precision-engineered fire ring technology, this gasket minimizes the risk of gasket failure, providing reliable performance for demanding builds.

Features:

• Increased Thickness: .080" thick gasket enhances durability and sealing capability under extreme conditions.
• Fire Ring Design: 4.560" wire outer diameter ensures a secure and high-strength seal, reducing the risk of leaks.
• Groove Recommendations: Radiused grooves should be machined to .008" in both the head and block, or .016"-.017" if using only one groove.
• Performance Compatibility: Suitable for engines up to 800hp, with dual-groove machining recommended for higher horsepower applications.

Upgrade to the Hamilton Cams .080" Fire Ring Head Gasket for enhanced reliability and sealing performance in your 1989-1998 Dodge Cummins 5.9L engine. Perfect for high-boost setups, this gasket ensures your engine can handle the demands of serious horsepower.

• Precise machining for grooves in the block and head is essential. We recommend a radiused cutter for all installations.
• It is imperative to verify that the head and block are flat to ensure proper sealing and to prevent gasket failure.

Installation:

• Apply a generous amount of lubrication to the nuts, washers, and threads of the studs to ensure consistent clamp load across all studs, preventing uneven pressure on the gasket that could lead to failure.
• Avoid exceeding the torque specifications provided by the manufacturer, as doing so can compromise the integrity of the fasteners.
• For initial installation, torque the fasteners to approximately 130 ft/lb, and then bring the engine up to operating temperature.
• After reaching operating temperature, perform a hot retorque to ensure all fasteners maintain proper tension.
• It is advisable to check the valve lash after each torque sequence, as retorquing may compress the head gasket and affect valve clearances; always re-check the torque before operating the engine at full load or RPM.
