Designed to withstand the rigorous demands of modern muscle cars, trucks, and SUVs, this gasket ensures reliable sealing under extreme conditions, preventing leaks and maintaining optimal engine compression.
Ideal for enthusiasts and professional builders alike, the MLX LHS gasket supports enhanced durability and longevity, making it a trusted choice for both street and track applications. Its precise 4.150" bore and .040" thickness are tailored to fit factory specifications, ensuring a perfect match for your engine rebuild or upgrade.
Cometic’s MLX LHS Head Gasket incorporates advanced materials and manufacturing techniques to deliver superior performance and reliability. Key features include:
The Cometic MLX LHS Head Gasket is crafted from premium alloy materials selected for their exceptional tensile strength and resistance to corrosion. The multi-layer steel design combines layers of stainless steel with precision-engineered sealing beads to create a robust barrier against combustion gases and coolant leaks. This construction allows the gasket to withstand the thermal and mechanical stresses typical of high-output 6.4L engines.
Cometic’s advanced manufacturing processes ensure tight tolerances and consistent thickness, which are critical for maintaining proper head-to-block sealing and preventing warpage or gasket failure. The use of copper, aluminum, and stainless steel alloys enhances the gasket’s ability to conform to surface irregularities while resisting degradation over time.
This head gasket is designed as a direct fit replacement for a broad range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 6.4L 392 and 6.4L SRT engines. Installation requires standard head gasket replacement procedures and should be performed by a qualified technician to ensure proper torque specifications and surface preparation.
No modifications to the engine block or cylinder head are necessary, making this gasket an excellent choice for rebuilds, repairs, or performance upgrades. Always verify compatibility with your specific vehicle year and model before installation.
Cometic Gasket supplies high-performance sealing solutions for motorsports and high-stress engine builds, with a strong focus on modern gasket materials like multi-layer steel (MLS) head gaskets. Their catalog spans head gaskets and complete gasket sets across a wide range of applications, helping builders maintain reliable combustion and fluid sealing under extreme pressure and heat.
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!
