Construction & Design:

The Cometic MLS Cylinder Head Gasket is crafted from multiple embossed layers of high-grade stainless steel, providing exceptional strength and flexibility. The outer layers are coated with Viton, a premium fluorocarbon elastomer known for its excellent resistance to heat, chemicals, and wear. This coating ensures a tight seal even under extreme thermal and mechanical stress.

The center shim layer is uncoated stainless steel, allowing for precise thickness customization to meet specific engine requirements. This multi-layer design enables the gasket to rebound and maintain sealing integrity despite the differential expansion rates of aluminum heads and cast iron blocks, preventing leaks and gasket failure.

Installation & Fitment:

This gasket is designed for direct replacement on a broad range of Dodge, Chrysler, Jeep, and Ram models equipped with the 5.7L Gen-3 Hemi engine. Installation requires standard cylinder head gasket replacement procedures with no special modifications needed. The gasket’s precise dimensions and coatings facilitate a straightforward installation, ensuring a reliable seal without the need for additional sealants or adhesives.
