Key Features

Built to meet the rigorous demands of high-performance and stock engines, the Cometic MLS Head Gasket delivers:

• Multi-layer steel construction for exceptional strength and durability under extreme conditions
• Embossed outer layers coated with heat-resistant Viton rubber to ensure superior sealing and chemical resistance
• Compressed operating thickness of 0.036" for precise fit and optimal compression
• Compatibility with both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks
• Resistance to corrosion and the ability to rebound under thermal cycling and mechanical stress
• Elimination of the need for additional sealants, simplifying installation and reducing potential leak points
• Designed to withstand shearing forces caused by dissimilar metal expansion
• Center shim layer of uncoated stainless steel allowing for customizable thickness adjustments

Construction & Design

The Cometic MLS Head Gasket features a robust multi-layer design composed of embossed stainless steel layers that provide both strength and flexibility. The outer layers are coated on both sides with Viton, a fluorocarbon elastomer known for its excellent heat resistance up to 250°C (482°F) and outstanding chemical durability. This coating ensures a reliable seal even under the high temperatures and pressures typical of performance VVT HEMI engines.

The gasket’s center shim layer is made from uncoated stainless steel, allowing for precise thickness customization to meet specific engine requirements. This layered construction effectively compensates for the different expansion rates of aluminum and cast iron components, maintaining a consistent seal and preventing leaks over time.

Installation & Fitment

This gasket is a direct-fit replacement designed specifically for Dodge, Jeep, Chrysler, and Ram 5.7L VVT HEMI engines from 2003 to 2015. Installation follows standard head gasket replacement procedures and does not require additional sealants due to the advanced Viton coating. Proper surface preparation and adherence to manufacturer torque specifications are essential to ensure optimal sealing performance and gasket longevity.

The gasket is engineered to accommodate the unique demands of both aluminum and cast iron engine blocks, making it suitable for a wide range of factory configurations within the specified model years.
