Precision Sealing Technology Built For The Cummins Workhorse

The Cometic C15266-054 MLX Cylinder Head Gasket is engineered specifically for 2019–2024 RAM 2500 and 3500 trucks running the 6.7L Cummins diesel engine. Featuring a 4.327 inch bore and a .054 inch compressed thickness, this gasket is designed to provide precise sealing for high-compression, high-heat applications. The MLX design uses multiple layers of stainless steel that enhance strength and improve rebound characteristics, making it highly resistant to blowouts and fatigue. A Fluor elastomer rubber coating is applied to the outer layers to ensure optimal adhesion and sealing across varying surface conditions. This combination of materials helps manage thermal expansion while providing the kind of durability heavy-duty diesel engines demand. Rated to handle temperatures up to 482 degrees Fahrenheit, it stands up to the harshest operating conditions you can throw at it. Whether you’re keeping things stock or building a performance setup, this gasket offers the reliability and longevity needed for long-term success on and off the road.
