• Superior corrosion resistance to withstand harsh engine environments
• Designed to rebound and maintain sealing integrity under varying load conditions and surface finishes
• Precision bore size of 3.950 inches to match factory specifications for the 5.7L Gen-3 Hemi
• Compatible with a broad range of Chrysler, Dodge, Jeep, and Ram models from 2003 through 2015
• Coated surfaces reduce the risk of gasket failure and improve longevity
• Engineered to handle the thermal expansion and contraction cycles typical of high-performance V8 engines

Construction & Design:

The Cometic MLS cylinder head gasket features a robust multi-layer steel design that combines strength with flexibility. The stainless steel layers provide excellent tensile strength and the ability to rebound after compression, which is critical for maintaining a tight seal over time. The embossed outer layers increase gasket surface contact, enhancing sealing capabilities.

Both sides of the gasket are coated with Viton rubber, a high-performance elastomer known for its resistance to heat, oil, and chemicals. This coating ensures the gasket maintains a secure seal even in the extreme conditions found in high-output engines. The gasket’s .075-inch thickness is optimized for the 5.7L Gen-3 Hemi, ensuring proper compression and fitment without modification.

Installation & Fitment:

This gasket is designed as a direct replacement for factory head gaskets on compatible vehicles, making installation straightforward for experienced mechanics and professional shops. It fits the right-hand side (RHS) cylinder head of the 5.7L Gen-3 Hemi engine and requires no modifications to the engine block or cylinder head.

Proper installation includes cleaning and inspecting the cylinder head and block surfaces to ensure a smooth, flat sealing area. Torque specifications and tightening sequences should be followed according to factory service manuals to guarantee optimal gasket performance and longevity.
