Construction & Design

The Cometic MLS Cylinder Head Gasket is constructed from multiple embossed layers of high-grade stainless steel, providing a balance of strength and flexibility necessary for modern engine sealing challenges. The outer layers are coated with Viton, a premium fluorocarbon elastomer known for its excellent resistance to heat, chemicals, and wear, ensuring a tight seal even under extreme thermal and mechanical stress.

The uncoated stainless steel center shim layer allows for precise thickness control, enabling the gasket to maintain sealing integrity despite the different expansion rates of aluminum cylinder heads and cast iron engine blocks. This multi-layer design effectively prevents leaks and gasket failure, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron configurations.

Installation & Fitment

This gasket is a direct replacement for a broad range of Dodge, Chrysler, Jeep, and Ram models equipped with the 5.7L Gen-3 Hemi engine. Installation follows standard cylinder head gasket replacement procedures with no special modifications required. The gasket’s precise dimensions and Viton coatings facilitate straightforward installation, eliminating the need for additional sealants or adhesives.

For optimal performance and longevity, always adhere to manufacturer torque specifications and installation guidelines when replacing the cylinder head gasket.
