Part #: C5526-066
Overview
The Cometic Gasket Aluminum MLS Head Gasket is engineered specifically for high-performance Chrysler 6.1L Gen-3 HEMI engines found in select Chrysler, Dodge, and Jeep SRT8 models from 2005 to 2010. This premium multi-layer steel (MLS) gasket provides a reliable, durable seal that withstands the extreme pressures and temperatures of modern high-output engines. Designed as a direct replacement for factory gaskets, it ensures optimal engine efficiency and long-lasting performance without the need for additional sealants.
Ideal for performance enthusiasts, professional mechanics, and engine rebuilders, this gasket is built to handle the unique challenges of aluminum block and head combinations, maintaining a tight seal under thermal cycling and high-stress conditions.
Key Features
Cometic’s Aluminum MLS Head Gasket incorporates advanced materials and precision engineering to deliver superior sealing and durability. Key features include:
- Multi-layer stainless steel construction for enhanced strength and flexibility
- Embossed outer layers coated with Viton rubber for exceptional heat, oil, and chemical resistance
- Compressed operating thickness of 0.066 inches for precise sealing on 6.1L HEMI engines
- Designed to withstand temperatures up to 250°C (482°F) for reliable performance under extreme heat
- Compatible with aluminum sleeved blocks and maintains OEM bore dimensions (4.125-inch bore)
- Center shim layer of uncoated stainless steel to accommodate differential expansion between aluminum heads and blocks
- No sealants required, simplifying installation and reducing potential failure points
- Corrosion resistant and engineered to rebound under thermal cycling for long-lasting durability
Construction & Design
This head gasket features a robust multi-layer steel design combining multiple embossed stainless steel layers to provide both strength and flexibility. The embossed outer layers are coated with Viton, a high-performance fluorocarbon elastomer known for its superior resistance to heat, oil, and chemicals, ensuring a reliable seal in harsh engine environments.
The center shim layer is made from uncoated stainless steel, allowing the gasket to precisely accommodate the different expansion rates between aluminum heads and aluminum or cast iron blocks. This design minimizes the risk of gasket failure due to shearing forces and maintains a consistent, leak-free seal throughout the engine’s operating range.

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!
