Overview:

The Cometic MLS (Multi-Layer Steel) head gasket is engineered specifically for the 6.1L Gen-3 Hemi engines found in select Chrysler, Dodge, and Jeep performance models from 2005 to 2010. Designed to provide a reliable and durable seal between the cylinder head and engine block, this gasket ensures optimal compression and prevents leaks under high-stress conditions. Ideal for enthusiasts and professional builders seeking a high-quality replacement or upgrade, the Cometic MLS gasket supports both street and track applications with superior sealing performance.

Its robust construction and advanced coating technology make it well-suited for engines subjected to elevated temperatures and pressures, maintaining integrity over extended use and demanding environments.

Key Features:

Cometic’s MLS head gasket incorporates advanced materials and design elements to deliver exceptional durability and sealing capability:

• Constructed from three to five layers of high-strength stainless steel for enhanced durability and resistance to warping.
• Outer layers are embossed to improve sealing contact and gasket rebound under load.
• Coated on both sides with heat-resistant Viton rubber, capable of withstanding temperatures up to 250°C (482°F).
• Designed to accommodate a .070 inch bore thickness, optimizing sealing for the 4.185 inch cylinder bore diameter.
• Corrosion-resistant materials ensure long-lasting performance in harsh engine environments.
• Precision manufacturing ensures consistent fitment and reliable sealing on Gen-3 Hemi cylinder heads.
• Compatible with factory and aftermarket cylinder heads without modification.
• Ideal for high-performance and heavy-duty applications, including street performance and occasional track use.

Construction & Design:

The Cometic MLS gasket features a multi-layer steel design that combines strength and flexibility. Stainless steel layers provide excellent resistance to heat and pressure, while the embossed outer layers enhance the gasket’s ability to conform to surface irregularities, ensuring a tight seal. The Viton coating on both sides adds a critical layer of chemical and heat resistance, protecting the gasket from oil, coolant, and combustion gases. This combination of materials and engineering results in a gasket that maintains sealing integrity under extreme thermal cycling and mechanical stress.

Manufactured with precision tolerances, the gasket fits perfectly to the 6.1L Gen-3 Hemi’s cylinder head and block surfaces, reducing the risk of leaks and improving engine reliability.

Installation & Fitment:

This Cometic MLS head gasket is a direct replacement for the factory gasket on 6.1L Gen-3 Hemi engines in the specified Chrysler 300, Dodge Charger, Dodge Magnum, Jeep Grand Cherokee, and Dodge Challenger models. Installation requires standard head gasket replacement procedures and should be performed by a qualified technician to ensure proper torque specifications and surface preparation. No modifications to the engine block or cylinder head are necessary, making it a straightforward upgrade or repair part.

What's Included:

• One Cometic MLS head gasket, .070 inch bore thickness, coated with Viton on both sides
