Overview

The Cometic Gasket MLS (Multi-Layer Steel) Cylinder Head Gasket is engineered to provide exceptional sealing performance for a broad range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 5.7L VVT HEMI engine. Designed to withstand the demanding conditions of high-output engines, this gasket ensures a reliable seal between the cylinder head and engine block, preventing leaks and maintaining optimal compression. It is an ideal choice for enthusiasts, professional mechanics, and anyone performing engine rebuilds, upgrades, or routine maintenance.

Built to support both aluminum-to-aluminum and aluminum-to-cast iron applications without requiring additional sealants, this gasket delivers durability and peace of mind, helping your engine maintain peak performance under rigorous conditions.

Key Features

Cometic’s MLS Cylinder Head Gasket incorporates advanced materials and design elements to ensure lasting reliability and superior sealing:

• Multiple embossed layers of stainless steel for enhanced strength and durability
• Outer layers coated with Viton rubber, a heat-resistant elastomer rated up to 250°C (482°F), providing excellent sealing under extreme thermal stress
• Compressed operating thickness of 0.098 inches for precise fitment and sealing integrity
• Engineered to withstand shearing forces between aluminum heads and cast iron or aluminum blocks
• Corrosion-resistant materials extend gasket life and maintain seal integrity over time
• No sealants required, simplifying installation and reducing the risk of leaks
• Center shim layer of uncoated stainless steel allows for thickness customization to meet specific engine requirements
• Specifically designed for Chrysler 5.7L Gen-3 HEMI engines with a 4.100-inch bore on the right-hand side (RHS)

Construction & Design

The Cometic MLS Cylinder Head Gasket features a meticulously engineered multi-layer construction using high-grade stainless steel. The embossed outer layers are coated on both sides with Viton, a premium fluorocarbon elastomer known for its exceptional heat resistance and chemical stability. This coating ensures a tight, durable seal even under high thermal and mechanical stress.

The multi-layer steel design provides the necessary flexibility to accommodate the different expansion rates of aluminum cylinder heads and cast iron or aluminum engine blocks. This reduces the risk of gasket failure caused by shearing forces, maintaining a consistent and reliable seal throughout the engine’s operating range.

Installation & Fitment

This gasket is a direct replacement for a wide range of Chrysler, Dodge, Jeep, and Ram models from 2003 through 2015 equipped with the 5.7L VVT HEMI engine.
