Overview

The Cometic Gasket MLS (Multi-Layer Steel) Cylinder Head Gasket is engineered to provide a superior sealing solution for high-performance 6.1L Gen-3 Hemi engines found in select Chrysler, Dodge, and Jeep models from 2005 to 2010. Designed to maintain optimal compression and prevent leaks under extreme conditions, this gasket is ideal for enthusiasts and professionals who demand durability and precision in their engine rebuilds or upgrades.

Built to withstand the rigorous thermal and mechanical stresses of modern performance engines, the Cometic MLS gasket ensures reliable sealing between the cylinder head and engine block without the need for additional sealants. Its compatibility with both aluminum and cast iron components makes it a versatile choice for maintaining engine integrity and performance.

Key Features

Crafted with advanced materials and construction techniques, the Cometic MLS Cylinder Head Gasket offers exceptional durability and sealing performance:

• Multi-layer stainless steel construction for enhanced strength and long-lasting durability
• Embossed outer layers coated with Viton rubber for superior sealing and heat resistance
• Compressed operating thickness of 0.098" for precise fit and optimal sealing
• Compatible with aluminum heads to aluminum blocks and aluminum heads to cast iron blocks
• Resistant to shearing forces caused by differing metal expansion rates
• Corrosion-resistant materials extend gasket life and reliability
• Center shim layer of uncoated stainless steel allows for customizable thickness adjustments
• Viton coating withstands temperatures up to 250°C (482°F) and harsh sealing environments
• No sealants required, simplifying installation and reducing potential failure points

Construction & Design

The Cometic MLS Cylinder Head Gasket is meticulously manufactured from multiple embossed layers of high-grade stainless steel. The outer layers feature a Viton rubber coating, a heat-resistant elastomer that maintains a tight seal under extreme thermal and mechanical stress. This coating is applied on both sides of the gasket, enhancing its ability to conform to surface imperfections and resist leaks.

The gasket’s center shim layer is made from uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. This multi-layer design not only improves sealing performance but also provides flexibility to absorb and rebound from the differential expansion of aluminum and cast iron engine components, preventing gasket failure due to shearing forces.
