Cometic MLS Head Gaskets with a 4.100" bore are precision-engineered for Gen III 5.7L Hemi engines found in a wide range of Chrysler, Dodge, Ram, and Jeep vehicles from 2003 through 2025. These multi-layer steel (MLS) gaskets deliver superior sealing performance, durability, and reliability, making them an excellent choice for both high-performance builds and everyday driving applications. Designed to withstand the demanding conditions of high-output engines, they ensure a secure seal between the cylinder head and engine block, preventing leaks and maintaining optimal compression.
Whether you are rebuilding your engine or upgrading for enhanced performance, Cometic MLS head gaskets provide the peace of mind needed to keep your Hemi running strong under all conditions.
Cometic MLS head gaskets combine advanced materials and design to offer unmatched sealing and longevity. Key features include:
These head gaskets feature a robust multi-layer steel design that combines strength and flexibility. The embossed outer layers are coated with heat-resistant Viton, a high-performance elastomer that provides excellent fluid sealing against coolant and oil leaks. The core shim layer is made from uncoated stainless steel, allowing for precise control over gasket thickness and compression ratios during engine assembly.
Cometic’s MLS gaskets are engineered to handle the thermal expansion differences between aluminum cylinder heads and cast-iron engine blocks, preventing gasket failure due to shearing forces. Their corrosion-resistant materials and resilient construction ensure long-lasting durability, even in high-stress environments.
Designed for direct replacement, Cometic MLS head gaskets fit a broad range of 5.7L Hemi engines in Chrysler, Dodge, Ram, and Jeep models from 2003 to 2025. Installation requires no additional sealants, making the process straightforward for professional mechanics and experienced enthusiasts alike. These gaskets are available for specific cylinder head orientations—left-hand side (LHS), right-hand side (RHS), or as a complete set—to ensure proper alignment and sealing.
Compatible vehicles include:
These MLS head gaskets are ideal for automotive enthusiasts, professional engine builders, and mechanics seeking a reliable, high-quality sealing solution for 5.7L Hemi engines. Whether rebuilding a stock engine, upgrading for performance, or maintaining a daily driver, Cometic MLS gaskets provide the durability and precision needed to ensure engine longevity and optimal performance.

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!
