The Cometic MLS (Multi-Layer Steel) Head Gaskets with a 4.055" bore are engineered specifically for the Gen III 6.1L SRT8 engines found in select Chrysler, Dodge, and Jeep models from 2006 to 2010. Designed to deliver superior sealing performance, these head gaskets are ideal for high-output engines that demand reliability under extreme conditions. Whether you are rebuilding your engine or upgrading for enhanced durability, Cometic MLS head gaskets provide a dependable solution that requires no additional sealants.

These gaskets accommodate a .040" compressed thickness, allowing fine-tuning of your engine’s compression ratio to optimize performance and longevity. They are perfect for enthusiasts and professionals seeking a high-quality gasket that withstands the rigors of performance driving and daily use alike.

Key Features:

Cometic MLS head gaskets incorporate advanced technology and materials to ensure maximum durability and sealing integrity:

• Multi-layer steel construction for enhanced strength and durability
• Designed to withstand the shearing forces between aluminum heads and aluminum or cast iron blocks
• Embossed outer layers coated with Viton, a heat-resistant fluoroelastomer rated up to 250°C (482°F)
• Corrosion-resistant stainless steel layers that rebound to maintain a tight seal
• Available in .040" compressed thickness to accommodate specific compression ratio requirements
• Ideal for high-output 6.1L SRT8 HEMI engines requiring reliable sealing under high pressure and temperature
• No sealants required, simplifying installation and reducing potential leak points
• Compatible with multiple vehicle models including Chrysler 300, Dodge Challenger, Charger, Magnum, and Jeep Grand Cherokee

Construction & Design:

Cometic’s MLS head gaskets are crafted from multiple layers of stainless steel, combining strength with flexibility to handle the stresses of modern high-performance engines. The outer layers are embossed and coated with Viton, a premium fluoroelastomer that provides excellent heat resistance and chemical durability. This coating ensures a reliable seal against combustion gases and coolant leaks, even under extreme thermal cycling.

The center shim layer is uncoated stainless steel, allowing precise control over gasket thickness and compression characteristics. This multi-layer design allows the gasket to maintain sealing integrity despite the differential expansion rates of aluminum heads and engine blocks, preventing leaks and head gasket failures common in high-performance applications.

Installation & Fitment:

These head gaskets are designed as direct replacements for the 6.1L SRT8 engines in the following vehicles:

• 2006–2010 Chrysler 300 6.1L SRT8
• 2008–2010 Dodge Challenger 6.1L SRT8
• 2006–2010 Dodge Charger 6.1L SRT8
• 2006–2008 Dodge Magnum 6.1L SRT8
• 2006–2010 Jeep Grand Cherokee 6.1L SRT8

Installation requires standard head gasket replacement procedures. No additional sealants are necessary, simplifying the installation process. For best results, ensure proper surface preparation and torque specifications are followed according to manufacturer guidelines.
