• Compressed operating thickness of 0.036 inches for optimal sealing and gasket rebound
• Designed to withstand shearing forces between aluminum cylinder heads and cast iron or aluminum engine blocks
• No sealants required, simplifying installation and reducing leak risks
• Corrosion-resistant materials for extended service life
• Precision fitment for right-hand side cylinder head applications on specified Dodge, Jeep, Ram, and Chrysler models
• Compatible with high-performance 6.4L Hemi engines, supporting both factory and modified setups

Construction & Design

The Cometic MLS Cylinder Head Gasket is expertly crafted from multiple layers of stainless steel, each embossed to enhance sealing capability and flexibility. The outer layers are coated on both sides with Viton, a premium fluorocarbon elastomer known for exceptional resistance to heat, oil, and chemical degradation. This coating ensures a tight, reliable seal even under harsh operating conditions.

The center shim layer is uncoated stainless steel, allowing precise thickness control to meet specific engine requirements. This multi-layer design provides superior strength and allows the gasket to rebound and maintain a consistent seal despite thermal expansion and contraction of engine components. Its robust construction effectively manages the differing expansion rates between aluminum heads and cast iron or aluminum blocks, preventing leaks and ensuring durability.

Installation & Fitment

Installation of the Cometic MLS Head Gasket is straightforward for experienced mechanics and professional shops. Designed as a direct replacement for the right-hand side cylinder head gasket on compatible vehicles, it requires no modifications or additional sealants. Proper surface preparation and adherence to manufacturer torque specifications are essential to achieve optimal sealing performance and longevity.

This gasket fits the following vehicles equipped with the 6.4L Gen-3 Hemi engine:
