Overview:

The Cometic Gasket 5.7L Gen-3 Hemi .045in MLS Cylinder Head Gasket is engineered to provide reliable, long-lasting sealing performance for a wide range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 5.7L Gen-3 Hemi engine. Designed for enthusiasts and professional mechanics alike, this gasket ensures optimal sealing between the cylinder head and engine block, preventing leaks and maintaining engine integrity under demanding conditions.

Ideal for both stock replacements and performance builds, the gasket supports high combustion pressures and thermal cycles typical of modern V8 engines. Its robust construction enhances engine durability and helps maintain consistent compression for improved efficiency and power delivery.

Key Features:

Cometic’s MLS cylinder head gasket incorporates advanced materials and design features to meet the rigorous demands of the 5.7L Gen-3 Hemi engine:

• Multi-Layer Steel (MLS) construction with three to five layers of stainless steel for superior strength and durability
• Embossed outer layers coated with heat-resistant Viton rubber for enhanced sealing and corrosion resistance
• Viton coating withstands temperatures up to 250°C (482°F), ensuring reliable performance in high-heat environments
• Precisely engineered 3.950-inch bore size for perfect fitment and sealing on the 5.7L Gen-3 Hemi
• Designed to resist blowouts and maintain seal integrity under high combustion pressures
• Compatible with a wide range of OEM surface finishes and load conditions
• Right-hand side (RHS) specific design for accurate installation and fitment

Construction & Design:

The Cometic MLS gasket is crafted from premium stainless steel layers that provide exceptional tensile strength and flexibility. This layered steel design allows the gasket to rebound and conform to surface irregularities, ensuring a tight seal even under extreme thermal expansion and contraction cycles. The embossed outer layers increase gasket surface contact, improving sealing efficiency.

Both sides of the gasket are coated with a durable Viton rubber material, which enhances sealing performance and protects against corrosion and chemical attack. Viton’s high heat resistance makes this gasket ideal for the demanding thermal environment of the 5.7L Gen-3 Hemi engine, maintaining integrity during prolonged high-temperature operation.

Installation & Fitment:

This gasket is a direct replacement for the right-hand side cylinder head on 5.7L Gen-3 Hemi engines found in numerous Chrysler, Dodge, Jeep, and Ram models from 2003 through 2015. Installation requires standard cylinder head gasket replacement procedures and does not necessitate any modifications to the engine block or head. Proper torque specifications and surface preparation are essential to ensure optimal sealing and longevity.
