5.9L Fire Ring Gasket – .056″ Thickness, 4.560″ x .105″ Wire
Upgrade your 5.9L Cummins engine with our premium Fire Ring Gasket, specifically designed to handle high cylinder pressures. Ideal for both street performance and competition builds, this gasket offers superior sealing and durability—especially when paired with proper machining, studs, and installation techniques.
Gasket Specifications
- Thickness: .056″ (1.4 mm)
- Wire Size: .105″
- Bore Diameter: 4.560″
- Groove Radius: .0120″ radiused groove in the head to a depth of .032″–.033″
Recommended Installation Guidelines
-
Machining for Flatness
- For best results, have both the head and block machined to ensure a perfectly flat sealing surface.
- Engines under 800 HP: Cutting grooves in just the head
- be sure to run 625 studs on vehicles over 800hp
-
Use a Radiused Cutter
- We strongly recommend a radiused cutter for all groove installations to achieve optimal sealing with the fire ring.
-
Proper Stud Installation & Lubrication
- Studs are a must for reliable clamping force—our competition gasket requires studs to handle elevated boost levels.
- Apply liberal lubrication on the nut, washer, and threads to ensure even clamp load.
- Never exceed manufacturer torque limits—fasteners at full torque contain immense potential energy.
-
Torque Procedure
- Initial Torque: 130 ft-lb for startup.
- Retorque Hot: After reaching operating temperature, retorque the studs while the engine is still warm.
- Check Valve Lash: Each retorque will further compress the gasket, affecting valve lash—always re-adjust as needed.
Why Choose Our Fire Ring Gasket?
- Engineered for High Cylinder Pressures: Superior sealing under extreme conditions.
- Long-Lasting Performance: Proven to handle high horsepower builds beyond 800 HP.
- Optimal Grooving & Clamping: Designed for precision machining and consistent stud clamp load.
- Enhanced Reliability: Reduce the risk of head-gasket failure in demanding diesel applications.
