Construction & Design

The Cometic MLX gasket features a premium multi-layer steel design that combines strength and flexibility to withstand the rigors of high-performance engines. The innovative stopper layer acts as a torque limiter, preventing over-tightening and subsequent gasket failure. This design ensures consistent clamping force across the cylinder head, maintaining a reliable seal even under extreme thermal cycling and high combustion pressures.

Additionally, the gasket’s high-temperature polymer coating and embossed sealing beads create a micro-seal that effectively blocks fluid leaks, including coolant and oil, while resisting chemical degradation. This meticulous engineering results in a gasket that balances durability with precision sealing for enhanced engine longevity.

Installation & Fitment

The Cometic MLX Head Gasket is a direct replacement designed to fit 2015–2019 Dodge Charger and Challenger Hellcat 6.2L engines without modification. It is critical to select the correct side orientation (RHS or LHS) and thickness (.040″ or .052″) to match your engine’s specifications and tuning goals. Installation should be performed by a qualified technician following OEM torque specifications and procedures to ensure optimal sealing performance.
