2005–2010 Chrysler 300C, 2006–2010 Dodge Charger, 2008–2010 Dodge Challenger, 2006–2008 Dodge Magnum, 2006–2010 Jeep Grand Cherokee 6.1L Gen-3 Hemi

Part #: C5876-098

Overview

The Cometic Gasket MLS (Multi-Layer Steel) Cylinder Head Gasket is engineered to provide exceptional sealing performance for high-output 6.1L Gen-3 Hemi engines found in select Chrysler, Dodge, and Jeep models. Designed to maintain a reliable seal between the cylinder head and engine block, this gasket prevents leaks under extreme thermal and mechanical stresses without requiring additional sealants.

Ideal for both performance enthusiasts and professional mechanics, this gasket supports aluminum-to-aluminum and aluminum-to-cast iron engine configurations. It ensures durability and sealing integrity even under the demanding conditions of street performance, occasional track use, and heavy-duty applications.

Key Features

Cometic’s MLS Cylinder Head Gasket incorporates advanced materials and design elements to meet the rigorous 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 and consistent sealing
• Embossed outer layers provide superior sealing against combustion pressures and coolant leaks
• Center shim layer of uncoated stainless steel tailored to exact 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 and reliability
• No sealants required, simplifying installation and reducing the risk of gasket failure

Construction & Design

The Cometic MLS gasket features a robust multi-layer steel construction that balances strength, flexibility, and corrosion resistance. Multiple layers of stainless steel allow the gasket to maintain a tight seal despite engine vibrations and thermal cycling. The embossed outer layers create a controlled surface contact area, enhancing sealing against combustion gases and coolant leaks.

Both sides of the gasket are coated with Viton rubber, providing excellent resistance to heat, oil, and coolant exposure. The precision-engineered center shim layer of uncoated stainless steel ensures exact thickness calibration to match engine specifications, optimizing compression and sealing integrity across combustion chambers and coolant passages.
