Key Features:

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

• Multi-layer steel (MLS) construction for enhanced strength and durability
• Embossed outer layers coated with heat-resistant Viton rubber for superior sealing
• Compressed operating thickness of 0.098 inches for precise fitment
• Compatible with aluminum heads to aluminum blocks and aluminum heads to cast iron blocks
• Resistant to corrosion and capable of withstanding shearing forces between dissimilar metals
• Center shim layer of uncoated stainless steel tailored for thickness requirements
• Heat resistance up to 250°C (482°F) thanks to Viton coating
• Designed for Chrysler 6.1L Gen-3 Hemi engines with a 4.100-inch bore diameter
• No sealants required, simplifying installation and reducing potential leak points

Construction & Design:

The Cometic MLS Cylinder Head Gasket is crafted from multiple embossed layers of stainless steel, providing a resilient and flexible sealing surface. The outer layers are coated on both sides with Viton, a high-performance fluoroelastomer known for its excellent heat resistance and chemical durability. This coating ensures a tight seal even under extreme thermal and mechanical stress.

The gasket’s center layer is an uncoated stainless steel shim that can be customized to meet specific thickness requirements, ensuring optimal compression and sealing for various engine configurations. This multi-layer design allows the gasket to absorb and rebound from the differential expansion between aluminum heads and cast iron or aluminum blocks, preventing leaks and maintaining engine integrity.

Installation & Fitment:

This MLS cylinder head gasket is designed for direct fitment on a range of Chrysler, Dodge, and Jeep vehicles equipped with the 6.1L Gen-3 Hemi engine. Installation requires no additional sealants, making the process straightforward for professional mechanics and experienced enthusiasts. Proper torque specifications and head bolt tightening sequences should be followed to ensure optimal sealing and longevity.
