Key Features

Cometic MLS head gaskets incorporate advanced materials and design elements to provide exceptional sealing and longevity. Key features include:

• Multi-layer stainless steel construction for increased strength and flexibility
• Embossed outer layers coated with Viton rubber for superior heat and chemical resistance
• Compressed operating thickness of 0.036" ensuring optimal sealing surface contact
• Designed to withstand shearing forces between dissimilar metals (aluminum and cast iron)
• Corrosion-resistant layers that maintain gasket integrity over time
• No need for additional sealants or adhesives during installation
• Precision engineered to fit 5.7L VVT HEMI engines from 2003–2008 and 2009–2024

Construction & Design

The Cometic MLS head gasket features multiple embossed layers of high-grade stainless steel, providing both strength and the ability to rebound under pressure. The outermost layers are coated on both sides with Viton, a heat-resistant fluorocarbon elastomer rubber that withstands temperatures up to 250°C (482°F). This coating enhances the gasket’s sealing capabilities against harsh environments, varying load conditions, and diverse surface finishes.

The center shim layer is uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. This multi-layer design effectively manages the differential expansion between aluminum heads and cast iron or aluminum blocks, preventing leaks and gasket failure.

Installation & Fitment

This MLS head gasket is a direct fit replacement for Dodge 5.7L VVT HEMI engines produced from 2003 to 2008 and 2009 to 2024. Installation requires standard head gasket replacement procedures and does not necessitate any modifications to the engine block or cylinder heads. The gasket’s design eliminates the need for additional sealants, simplifying the installation process and ensuring a reliable seal.

Proper surface preparation and torque specifications should be followed to maximize gasket performance and longevity.
