Overview:

The Cometic Gasket MLS Cylinder Head Gasket is engineered to deliver superior sealing performance for high-output 4.7L PowerTech engines found in select Jeep, Dodge, and Mitsubishi vehicles from 1999 to 2007. Designed for enthusiasts and professional mechanics alike, this gasket ensures reliable durability and leak-free operation under demanding conditions. Its multi-layer steel construction provides excellent resistance to heat, pressure, and corrosion, making it an ideal upgrade or replacement for factory gaskets.

Whether you are rebuilding your engine or upgrading for enhanced reliability, this MLS gasket offers a precision fit and long-lasting performance without the need for additional sealants. It is perfectly suited for aluminum-to-aluminum and aluminum-to-cast iron engine configurations, accommodating the unique stresses these materials impose.

Key Features:

Cometic’s MLS Cylinder Head Gasket incorporates advanced materials and design elements to meet the rigorous demands of modern engines:

• Multi-layer steel (MLS) construction for increased strength and durability
• Embossed outer layers coated with heat-resistant Viton rubber for superior sealing
• Compressed operating thickness of 0.030" for precise fitment and optimal compression
• Corrosion-resistant stainless steel layers that rebound to maintain a tight seal
• Designed to withstand shearing forces between aluminum heads and cast iron blocks
• Center shim layer of uncoated stainless steel customizable for thickness requirements
• Heat resistance up to 250°C (482°F) thanks to Viton coating
• No sealants required, simplifying installation and reducing potential failure points
• Embossed sealing beads enhance gasket compression and leak prevention

Construction & Design:

The gasket features multiple embossed layers of premium stainless steel, providing exceptional strength and flexibility. The outer layers are coated with Viton, a high-performance fluoroelastomer rubber known for its excellent heat resistance and chemical stability. This coating ensures a reliable seal against combustion gases and coolant leaks even under extreme thermal cycling.

The center shim layer is made from uncoated stainless steel, allowing precise control over gasket thickness to match engine specifications. This multi-layer design enables the gasket to absorb and compensate for the differential expansion between aluminum cylinder heads and cast iron engine blocks, preventing warping and maintaining a consistent seal.

Installation & Fitment:

This MLS cylinder head gasket is a direct replacement for the Chrysler 4.7L PowerTech engines installed in the following vehicles:

• Jeep Grand Cherokee (1999–2007) including Laredo, Limited, Overland, and Special Edition trims
