2003–2015 Dodge, Chrysler, Jeep, Ram 5.7L VVT HEMI

Part #: C5749-080

Overview

The Cometic Gasket MLS (Multi-Layer Steel) Cylinder Head Gasket is engineered to deliver superior sealing performance for Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 5.7L VVT HEMI engine. Designed to handle the rigorous demands 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 excellent 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 the need for additional sealants, this gasket offers durability and peace of mind. It helps maintain peak engine performance under demanding conditions, making it ideal for daily drivers, towing, and performance upgrades alike.

Key Features

Cometic’s MLS Cylinder Head Gasket incorporates advanced materials and precision engineering to ensure lasting reliability and exceptional sealing integrity:

• Multiple embossed layers of high-grade 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 consistent sealing
• 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 premium stainless steel. The embossed outer layers are coated on both sides with Viton, a high-performance fluorocarbon elastomer known for its exceptional heat resistance and chemical stability. This coating ensures a tight, durable seal even under intense 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.
