• Ideal for high-stress applications found in SRT8 variants of Chrysler 300C, Dodge Charger, Dodge Magnum, Jeep Grand Cherokee, and Dodge Challenger

Construction & Design

The Cometic MLS gasket features a robust multi-layer steel design that balances strength and flexibility. The stainless steel layers provide excellent tensile strength and resist warping under high combustion pressures and thermal cycling. The embossed design increases contact pressure at critical sealing points, ensuring a reliable seal between the cylinder head and engine block.

Both sides of the gasket are coated with a Viton rubber compound, known for its outstanding resistance to heat, oil, and coolant exposure. This coating extends the gasket’s lifespan and maintains sealing integrity even in the demanding environments of the 6.1L Gen-3 Hemi engine.

Installation & Fitment

This gasket is a direct factory replacement for the specified Chrysler, Dodge, and Jeep models equipped with the 6.1L Gen-3 Hemi engine. Installation follows 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 required, making it a straightforward upgrade for performance rebuilds or repairs.
