Overview

The Cometic Gasket MLS Head Gasket is engineered to deliver superior sealing performance for the Dodge Ram 1500 equipped with the 5.7L VVT HEMI engine from 2003 through 2024. Designed for high-output applications, this multi-layer steel (MLS) gasket ensures reliable sealing between the cylinder head and engine block without the need for additional sealants. It is an essential upgrade for enthusiasts and professionals seeking durability and consistent performance in demanding driving conditions.

Ideal for both aluminum-to-aluminum and aluminum-to-cast iron engine configurations, this gasket effectively handles the thermal and mechanical stresses common in modern engines. Whether you are rebuilding your engine or upgrading for enhanced reliability, the Cometic MLS head gasket offers peace of mind with its robust construction and precise fitment.

Key Features

Cometic’s MLS head gasket incorporates advanced materials and design elements to meet the rigorous demands of today’s engines:

• Multi-layer steel construction for increased strength and durability
• Embossed outer layers coated with Viton rubber for superior sealing and heat resistance
• Compressed operating thickness of 0.030" to maintain optimal sealing under pressure
• Designed to withstand shearing forces between aluminum heads and cast iron or aluminum blocks
• Corrosion-resistant stainless steel layers for extended service life
• Viton coating rated for heat resistance up to 250°C (482°F)
• Center shim layer of uncoated stainless steel to accommodate precise thickness requirements
• No sealants required, simplifying installation and reducing potential failure points
• Right-hand side orientation for exact fitment on the specified engine

Construction & Design

The Cometic MLS head gasket features multiple embossed layers of stainless steel, providing exceptional strength and flexibility. The outer layers are coated with Viton, a high-performance fluorocarbon elastomer known for its excellent heat resistance and chemical stability. This coating ensures a tight seal even under extreme temperatures and varying surface finishes.

The gasket’s center shim layer is uncoated stainless steel, allowing for precise thickness control and the ability to rebound after compression. This multi-layer design effectively manages the differential expansion between aluminum heads and cast iron or aluminum blocks, preventing leaks and gasket failure over time.

Installation & Fitment

This MLS head gasket is specifically designed for the right-hand side of the 5.7L VVT HEMI engine found in Dodge Ram 1500 models from 2003 to 2008 and 2009 to 2024. It installs without the need for additional sealants, streamlining the assembly process and reducing installation errors. Proper torque specifications and head bolt tightening sequences should be followed to ensure optimal sealing and longevity.
