The Cometic Gasket MLS (Multi-Layer Steel) Cylinder Head Gasket is engineered to deliver superior sealing performance for high-output engines, specifically designed for select Dodge, Ram, and Jeep models equipped with the 4.7L PowerTech engine. This gasket is ideal for enthusiasts and professional mechanics seeking a reliable, durable solution that withstands the demanding conditions of modern engines without the need for additional sealants.

Built to accommodate the thermal and mechanical stresses between aluminum heads and either aluminum or cast iron blocks, this gasket ensures a consistent, leak-free seal that enhances engine longevity and performance. It is a direct replacement part that fits a wide range of 2008 to 2013 Dodge Dakota, Durango, Ram 1500, and Jeep Grand Cherokee vehicles.

Key Features:

Designed with advanced materials and precision engineering, the Cometic MLS Cylinder Head Gasket offers the following key benefits:

• Multi-layer steel construction for enhanced strength and durability
• Embossed outer layers coated with Viton rubber for superior heat resistance and sealing
• Compressed operating thickness of 0.030" to maintain optimal gasket compression
• Compatible with aluminum-to-aluminum and aluminum-to-cast iron engine configurations
• Corrosion-resistant stainless steel layers that rebound to maintain a tight seal
• Viton coating withstands temperatures up to 250°C (482°F) for harsh sealing environments
• Requires no additional sealants, simplifying installation and reducing potential failure points
• Precision fit for 94mm bore engines, ensuring proper alignment and sealing

Construction & Design:

The Cometic MLS Cylinder Head Gasket is constructed from multiple embossed layers of stainless steel, providing exceptional strength and flexibility. The outer layers are coated on both sides with Viton, a high-performance fluorocarbon elastomer known for its excellent resistance to heat, chemicals, and wear. This coating enhances the gasket’s ability to maintain a reliable seal under extreme operating conditions.

The center shim layer is made of uncoated stainless steel, allowing for precise thickness variation to meet specific engine requirements. This multi-layer design effectively manages the shearing forces generated between dissimilar materials such as aluminum heads and cast iron blocks, preventing leaks and gasket failure over time.

Installation & Fitment:

This gasket is a direct fit replacement for the following vehicles equipped with the 4.7L PowerTech engine:

• Dodge Dakota (2008–2010, 2011)
• Dodge Durango (2008–2009)
