Part #: C5526-098
Overview
The Cometic Gasket MLS (Multi-Layer Steel) Cylinder Head Gasket is engineered specifically for the Chrysler 6.1L Gen-3 HEMI engine, delivering exceptional sealing performance for high-output applications. Designed to meet the rigorous demands of performance enthusiasts and professional engine builders, this gasket ensures reliable durability under extreme conditions, including spirited driving and track use.
Compatible with a broad range of Chrysler, Dodge, and Jeep SRT8 models, the gasket supports both aluminum-to-aluminum and aluminum-to-cast iron block configurations. Its advanced design eliminates the need for additional sealants, simplifying installation while maintaining a clean, leak-free seal.
Key Features
Cometic’s MLS head gasket incorporates cutting-edge materials and precision engineering to provide superior sealing integrity and longevity:
- Constructed from multiple embossed layers of stainless steel for enhanced strength and flexibility
- Outer layers coated with Viton rubber, a heat-resistant elastomer rated up to 250°C (482°F)
- Compressed operating thickness of 0.036 inches for precise and consistent sealing
- Designed to withstand shearing forces between aluminum heads and both aluminum and cast iron blocks
- Corrosion-resistant materials ensure long-lasting performance under harsh engine conditions
- Center shim layer of uncoated stainless steel allows for thickness customization to match engine tolerances
- Specifically sized for a 4.125-inch bore with compatibility for aluminum sleeved blocks
- No sealants required, reducing installation complexity and potential leak points
Construction & Design
The Cometic MLS head gasket features a robust multi-layer steel construction that balances durability with flexibility. Each stainless steel layer is precision-embossed to maintain a secure seal under extreme pressure and temperature fluctuations typical of high-performance engines.
The outer layers are coated with Viton, a premium fluorocarbon elastomer known for its exceptional heat resistance and chemical stability, ensuring the gasket maintains integrity over prolonged use. The center shim layer, made from uncoated stainless steel, provides rigidity and allows for precise thickness adjustments, effectively managing differential expansion between aluminum heads and cast iron or aluminum blocks to prevent leaks and gasket failure.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
