Construction & Design

This head gasket features a multi-layer steel (MLS) design, the industry standard for high-performance and racing engines. Multiple layers of high-grade steel provide exceptional strength and flexibility, maintaining a tight seal even under extreme combustion pressures. The embossed outer layers are coated with Viton, a high-performance fluoroelastomer that resists heat, oil, and chemical degradation, significantly extending gasket life and reliability.

Integrated HP Shim technology enhances clamping force around the combustion chamber, which is critical for the open deck design of the Hellcat engine block. This ensures the gasket maintains a consistent seal, preventing leaks that could lead to performance loss or engine damage.

The Cometic .044 MLX Head Gasket is designed as a direct replacement for the right-hand side cylinder head on 2015–2019 Dodge Challenger SRT Hellcat, Dodge Challenger SRT Hellcat Redeye (2019), and Dodge Charger SRT Hellcat models. 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 necessary, making this gasket an ideal upgrade or replacement part to maintain or restore the integrity of your Hellcat’s engine sealing system.
