Cummins 2019+ 6.7L ISB .054in MLX Head Gasket

The Cummins 2019+ 6.7L ISB .054in MLX Head Gasket by Cometic Gaskets is a precision-engineered cylinder head gasket engineered for the 2019–2024 Dodge Cummins diesel platform. This multi-layer steel head gasket features a 4.327-inch bore diameter and 0.054-inch compression thickness, delivering the sealing integrity required for sustained diesel engine performance under extreme cylinder pressures. Cometic's advanced gasket technology ensures reliable combustion chamber sealing across the full operating temperature and boost range of the ISB engine.

The multi-layer steel construction resists deformation and maintains consistent clamp load across repeated thermal cycling—critical for diesel engines that experience sustained high combustion pressures and temperature swings. The 0.054-inch compression thickness is calibrated specifically for the ISB's combustion chamber geometry and compression ratio, ensuring optimal gasket performance without over-compression or excessive blow-by. The 4.327-inch bore specification matches the cylinder dimensions of the Cummins 6.7L ISB, guaranteeing precise port and coolant hole alignment. This gasket is designed to restore factory-level sealing on both stock engines and mildly modified platforms, making it suitable for both repair work and performance rebuilds.

Dodge Cummins owners performing head gasket service on 2019–2024 ISB engines—whether addressing a failed OEM gasket or preparing for long-term durability upgrades—rely on Cometic's OEM-compatible gasket solutions. This gasket is specified for in-frame or complete engine rebuilds on trucks used for towing, hauling, or daily service. The multi-layer design provides superior durability compared to single-layer gaskets, extending service intervals and reducing the risk of head gasket failure under boost. Proper installation with factory-specified torque sequences and a clean deck surface is essential for optimal sealing performance.
