Overview:

The Cometic Gasket MLS (Multi-Layer Steel) Cylinder Head Gasket is engineered to deliver superior sealing performance for a wide range of Jeep and Dodge vehicles, including the Jeep Grand Cherokee (1999–2004), Dodge Dakota (2000–2005), Dodge Durango (2000–2005), and Dodge Ram 1500, 2500, and 3500 models from 2002 through 2019. Designed for high-output engines, this gasket ensures reliable sealing without the need for additional sealants, making it an essential upgrade or replacement part for enthusiasts and professionals alike.

Built to withstand the demanding conditions of modern engines, the Cometic MLS gasket is ideal for applications involving aluminum heads mated to either aluminum or cast iron blocks. Its robust construction resists the shearing forces caused by differing metal expansion rates, ensuring long-lasting durability and engine protection.

Key Features:

Cometic’s MLS Cylinder Head Gasket combines advanced materials and precision engineering to meet the rigorous demands of performance and reliability. Key features include:

• Multiple embossed layers of stainless steel for enhanced strength and flexibility
• Outer layers coated with Viton rubber, a heat-resistant elastomer rated up to 250°C (482°F)
• Compressed operating thickness of 0.036 inches for optimal sealing
• Corrosion-resistant construction to extend gasket life
• Designed to handle the shearing forces between aluminum heads and cast iron or aluminum blocks
• No sealants required, simplifying installation and reducing potential leak points
• Precision fitment for specific Chrysler 4.7L PowerTech engines and compatible models
• Embossed outer layers improve sealing under high load and temperature conditions

Construction & Design:

The Cometic MLS gasket features a sophisticated multi-layer steel design, consisting of several embossed stainless steel layers that provide exceptional strength and the ability to rebound under pressure. The outermost layers are coated with Viton, a durable fluorocarbon elastomer known for its resistance to heat, oil, and chemical degradation. This coating enhances the gasket’s sealing capability across a variety of harsh operating environments.

The center shim layer is made from uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. This layered construction not only improves durability but also ensures consistent sealing performance, even under the thermal cycling and mechanical stresses typical of high-performance engines.

Installation & Fitment:

The Cometic MLS Cylinder Head Gasket is designed for direct replacement on a wide range of Jeep and Dodge vehicles equipped with the 4.7L PowerTech engine and compatible Ram models. Installation requires standard head gasket replacement procedures and does not necessitate any modifications or additional sealants, thanks to its advanced sealing technology.
