Overview:

The Cometic Gasket MLS (Multi-Layer Steel) Cylinder Head Gasket is engineered to deliver superior sealing performance for high-output engines, specifically designed for Chrysler 300, Dodge Charger, Dodge Magnum, Jeep Grand Cherokee, and Dodge Challenger models equipped with the 6.1L Gen-3 Hemi engine. This gasket ensures a reliable seal between the cylinder head and engine block, preventing leaks under extreme operating conditions without the need for additional sealants.

Ideal for enthusiasts and professional mechanics alike, this gasket supports both aluminum-to-aluminum and aluminum-to-cast iron engine configurations, maintaining durability and integrity even under the stress of thermal expansion and shearing forces.

Key Features:

Cometic’s MLS Cylinder Head Gasket incorporates advanced materials and design elements to meet the demands of modern performance engines:

• Constructed from multiple embossed layers of stainless steel for enhanced strength and flexibility
• Outer layers coated with Viton rubber, a heat-resistant elastomer rated up to 250°C (482°F)
• Compressed operating thickness of 0.098 inches for precise sealing
• Embossed outer layers provide superior sealing against combustion pressures and coolant leaks
• Center shim layer of uncoated stainless steel tailored to specific thickness requirements
• Designed to withstand shearing forces between dissimilar metals such as aluminum heads and cast iron blocks
• Corrosion-resistant materials ensure long-lasting durability
• No sealants required, simplifying installation and reducing the risk of gasket failure

Construction & Design:

The Cometic MLS gasket features a multi-layer steel construction that combines strength, flexibility, and corrosion resistance. The multiple layers of stainless steel allow the gasket to rebound and maintain a tight seal despite engine vibrations and thermal cycling. The embossed outer layers enhance sealing by creating a controlled surface contact area, while the Viton rubber coating on both sides provides excellent resistance to heat, oil, and coolant exposure.

The center shim layer is precision-engineered from uncoated stainless steel, allowing for exact thickness calibration to match engine specifications. This design ensures optimal compression and sealing integrity across the combustion chamber and coolant passages.
