2011–2024 Dodge 6.4L 392 HEMI
Part #: C15172-044
Overview
The Cometic MLS Head Gasket with a 4.150" bore and .044" thickness is engineered specifically for the Dodge 6.4L 392 HEMI engines from 2011 through 2024. Designed to meet the demands of high-output performance engines, this multi-layer steel (MLS) gasket ensures superior sealing reliability without the need for additional sealants. Whether you are rebuilding or upgrading your HEMI engine, this gasket provides the durability and precision required to maintain optimal engine performance and longevity.
Ideal for enthusiasts and professional engine builders alike, the Cometic MLS gasket is built to withstand the extreme conditions found in modern high-performance applications, including the thermal and mechanical stresses of aluminum-to-aluminum or aluminum-to-cast iron engine assemblies.
Key Features
Cometic MLS Head Gaskets incorporate advanced materials and design features to deliver exceptional sealing performance and durability:
- Multi-layer steel construction for enhanced strength and flexibility
- Embossed outer layers coated with heat-resistant Viton rubber for superior sealing
- Compressed operating thickness of 0.098" for precise fit and sealing
- Designed to handle the shearing forces between aluminum heads and blocks or cast iron blocks
- Corrosion-resistant stainless steel layers for long-lasting durability
- Center shim layer of uncoated stainless steel to accommodate thickness variations
- Viton coating rated to withstand temperatures up to 250°C (482°F)
- No additional sealants required, simplifying installation and reducing potential failure points
Construction & Design
The Cometic MLS Head Gasket is constructed from multiple embossed layers of high-grade stainless steel, providing a robust yet flexible sealing surface. The outer layers are coated with Viton, a fluorocarbon elastomer known for its excellent heat resistance and chemical stability, ensuring a reliable seal under extreme thermal and mechanical loads. The embossed design enhances gasket sealing by allowing controlled compression and rebound, which compensates for surface irregularities and thermal expansion differences between engine components.
The center shim layer is uncoated stainless steel, carefully engineered to maintain consistent gasket thickness and accommodate the specific bore size and thickness requirements of the 6.4L 392 HEMI engine. This multi-layer approach results in a gasket that resists corrosion, maintains integrity under high cylinder pressures, and adapts to the dynamic environment of modern performance engines.
Installation & Fitment
This MLS head gasket is a direct fit replacement for Dodge 6.4L 392 HEMI engines from model years 2011 through 2024. It is designed for use with both aluminum cylinder heads and blocks, as well as aluminum heads on cast iron blocks, making it versatile for various engine rebuilds or upgrades. Installation requires standard head gasket replacement procedures, with no need for additional sealants or special treatments, simplifying the process and ensuring consistent results.
Proper surface preparation and torque specifications should be followed to maximize sealing performance and longevity. This gasket is engineered to handle the factory and aftermarket performance levels typical of the 6.4L HEMI platform.

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!
