Construction & Design:

The Cometic MLS Cylinder Head Gasket is crafted from multiple embossed layers of stainless steel, providing a resilient and flexible sealing surface. The outer layers are coated on both sides with Viton, a high-performance fluoroelastomer known for its excellent heat resistance and chemical durability. This coating ensures a tight seal even under extreme thermal and mechanical stress.

The gasket’s center layer is an uncoated stainless steel shim that can be customized to meet specific thickness requirements, ensuring optimal compression and sealing for various engine configurations. This multi-layer design allows the gasket to absorb and rebound from the differential expansion between aluminum heads and cast iron or aluminum blocks, preventing leaks and maintaining engine integrity.

Installation & Fitment:

This MLS cylinder head gasket is designed for direct fitment on a range of Chrysler, Dodge, and Jeep vehicles equipped with the 6.1L Gen-3 Hemi engine. Installation requires no additional sealants, making the process straightforward for professional mechanics and experienced enthusiasts.
