C5441-040

Overview:

The Cometic MLS Cylinder Head Gasket is engineered to provide superior sealing performance for high-output Chrysler 6.1L Gen-3 Hemi engines. Designed specifically for select Chrysler 300, Dodge Charger, Dodge Magnum, Jeep Grand Cherokee, and Dodge Challenger models from 2005 to 2010, this gasket ensures reliable sealing under demanding conditions. Ideal for enthusiasts and professionals seeking durability and precision, it offers enhanced strength and longevity compared to conventional gaskets.

Built to withstand the rigors of performance driving and daily use alike, the Cometic MLS gasket helps maintain optimal engine compression and prevents leaks, contributing to consistent power delivery and engine reliability.

Key Features:

This multi-layer steel (MLS) gasket incorporates advanced materials and design elements to meet the needs of high-performance applications:

• Constructed with three to five layers of high-grade stainless steel for exceptional strength and durability
• Embossed outer layers enhance sealing by conforming to cylinder head and block surfaces
• Coated on both sides with heat-resistant Viton rubber, rated up to 250°C (482°F), for superior chemical and thermal resistance
• Specifically designed for a 4.125-inch bore, matching factory cylinder dimensions for precise fitment
• Resistant to corrosion and capable of rebounding to maintain a tight seal under varying load conditions
• Compatible with factory surface finishes and engineered to handle harsh sealing environments
• Ideal for high-performance and street-driven SRT8 variants of the listed vehicles

Construction & Design:

The Cometic MLS gasket features a robust multi-layer steel construction that combines strength with flexibility. The stainless steel layers provide excellent tensile strength and resistance to warping, while the embossed design ensures a tight seal by increasing contact pressure at critical sealing points. Both sides of the gasket are coated with a Viton rubber compound, which offers outstanding resistance to heat, oil, and coolant exposure, extending gasket life and reliability.

This design allows the gasket to maintain sealing integrity even under extreme thermal cycling and high combustion pressures typical of the 6.1L Gen-3 Hemi engines found in these performance vehicles.

Installation & Fitment:

The Cometic MLS Cylinder Head Gasket is a direct replacement for factory gaskets on the specified Chrysler, Dodge, and Jeep models equipped with the 6.1L Gen-3 Hemi engine. 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, guaranteeing a straightforward upgrade.
