Construction & Design

The Cometic MLX LHS Head Gasket features a multi-layer steel (MLS) design, which is the industry standard for modern performance head gaskets. The layers are precision stamped and embossed to ensure a consistent and tight seal. The outer layers are coated with Viton, a high-quality fluoropolymer elastomer, which enhances chemical resistance and prevents gasket degradation from oil, coolant, and combustion byproducts.

HP Shim technology incorporated in the gasket increases the clamp load around the combustion chamber, improving the seal on open deck engine blocks like the 5.7L Hemi. This design reduces the risk of head gasket failure due to combustion pressure leaks, making it suitable for both stock rebuilds and mild to moderate performance upgrades.

Installation & Fitment

This head gasket is designed for direct fitment on 5.7L Hemi engines found in various Chrysler, Dodge, Jeep, and Ram models from 2002 through 2026. It is recommended to replace both head gaskets (purchase quantity of two) to ensure proper sealing on both cylinder heads. Installation should be performed by a qualified technician following manufacturer torque specifications and procedures to guarantee optimal performance and longevity.

No modifications are required for installation when used with compatible engines, making it a straightforward upgrade or replacement part for engine rebuilds and repairs.
