Overview:

The Cometic MLS Head Gasket is engineered specifically for the 6.1L Gen-3 HEMI engines found in select Chrysler, Dodge, and Jeep performance models from 2005 to 2010. Designed to deliver superior sealing performance, this multi-layer steel (MLS) gasket is ideal for high-output engines that demand reliability under extreme conditions. It eliminates the need for additional sealants, providing a durable, leak-free seal between the cylinder head and engine block.

Whether you are rebuilding, upgrading, or maintaining your SRT8-powered Chrysler 300, Dodge Charger, Dodge Magnum, Jeep Grand Cherokee, or Dodge Challenger, this gasket ensures optimal engine integrity and longevity. Its robust construction supports the stresses of aluminum-to-aluminum or aluminum-to-cast iron applications, making it a trusted choice for enthusiasts and professional mechanics alike.

Key Features:

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

• Multi-layer steel construction for enhanced strength and durability
• Outer layers coated with Viton rubber for superior heat and chemical resistance
• Embossed stainless steel layers to improve sealing and gasket rebound
• Compressed operating thickness of 0.098" for precise fit and sealing
• Compatible with aluminum heads to aluminum or cast iron blocks
• Resistant to corrosion and shearing forces caused by dissimilar metals
• Center shim layer of uncoated stainless steel tailored for thickness requirements
• No additional sealants required for installation
• Heat resistant up to 250°C (482°F) thanks to Viton coating

Construction & Design:

The Cometic MLS Head Gasket features a sophisticated multi-layer steel design that combines strength and flexibility. The gasket consists of multiple embossed stainless steel layers, which provide the necessary resilience to maintain a tight seal under the high pressures and temperatures typical of performance engines. The outer layers are coated with Viton, a high-grade fluoroelastomer rubber known for its exceptional heat resistance and chemical durability, ensuring the gasket withstands harsh operating environments.

The center shim layer is uncoated stainless steel, allowing for precise thickness calibration to match engine specifications. This layered construction not only enhances sealing capability but also accommodates the differential expansion rates between aluminum heads and cast iron or aluminum blocks, preventing leaks and gasket failure.

Installation & Fitment:

This MLS head gasket is designed as a direct replacement for the 6.1L HEMI engines in the following vehicles: Chrysler 300 C SRT8 (2005–2010), Dodge Charger SRT8 (2006–2010), Dodge Magnum SRT8 (2006–2008), Jeep Grand Cherokee SRT8 (2006–2010), and Dodge Challenger SRT8 (2008–2010). Installation requires standard head gasket replacement procedures and does not necessitate any modifications to the engine block or cylinder heads.

Because the gasket is engineered to precise OEM specifications, it ensures a perfect fit and reliable sealing performance, making it suitable for both professional engine rebuilds and enthusiast upgrades.
