Cometic Gasket Chrysler 6.2L Hellcat MLX Head Gasket (LEFT): Dodge Challenger SRT Hellcat (15-19) / Charger SRT Hellcat (15-19)

Cometic Gasket Head Gasket

2015–2019 Dodge Challenger SRT Hellcat / Charger SRT Hellcat 6.2L Hellcat MLX

C15293-044

Overview:

The Cometic Gasket Chrysler 6.2L Hellcat MLX Head Gasket (LEFT) is engineered specifically for high-performance applications in Dodge Challenger and Charger SRT Hellcat models from 2015 to 2019. Designed to withstand the extreme pressures and temperatures generated by the Hellcat’s supercharged 6.2L Gen-3 Hemi engine, this head gasket ensures a reliable seal between the cylinder head and engine block. It is ideal for enthusiasts and professional builders seeking durability and enhanced sealing performance in demanding conditions.

Featuring advanced HP shim technology, this gasket increases clampload around the combustion chamber, improving sealability on the open deck block architecture of the Hellcat engine. This results in better resistance to head lift and combustion leaks, which are critical for maintaining engine integrity under high boost and power levels.

Key Features:

Cometic’s Hellcat MLX head gasket offers a range of features tailored for performance and reliability:

• HP shim technology for increased clampload and superior sealing
• Designed specifically for the Chrysler 6.2L Hellcat Gen-3 Hemi engine
• .044 inch thickness optimized for performance and durability
• 4.150 inch bore size matching factory specifications
• Left-hand side (LHS) embossed outer layers for enhanced gasket integrity
• Outer layers coated with Viton for chemical resistance and longevity
• Compatible with Dodge Challenger SRT Hellcat (2015–2019) and Charger SRT Hellcat (2015–2019)
• Precision manufacturing ensures consistent fit and performance

Construction & Design:

The Cometic MLX head gasket is constructed using multi-layer steel (MLS) technology, which provides exceptional strength and flexibility to handle the Hellcat’s high cylinder pressures. The gasket’s embossed outer layers are coated with Viton, a high-performance elastomer that offers excellent resistance to heat, oil, and fuel exposure. This coating helps maintain a tight seal over extended use and harsh operating conditions.

The inclusion of HP shim technology enhances the gasket’s ability to maintain clampload around the combustion chamber, reducing the risk of head gasket failure due to combustion gas leakage or head lift. The gasket thickness of .044 inches is carefully selected to balance sealing capability with proper engine compression and performance.

Installation & Fitment:

This head gasket is designed as a direct replacement for the left-hand side cylinder head on 2015 to 2019 Dodge Challenger SRT Hellcat, Dodge Challenger SRT Hellcat Redeye 2019, and Dodge Charger SRT Hellcat models equipped with the 6.2L Hellcat 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 are necessary for fitment, as the gasket matches OEM bore dimensions and mounting points precisely. Proper installation will ensure optimal sealing performance and engine reliability under high-performance conditions.
