Precision Engineered To Withstand Heat Pressure And Abuse

The Cometic C5955-067 MLX Cylinder Head Gasket is a performance-grade solution designed for high-stress diesel applications. Featuring a multi-layered construction with five layers of proprietary MLX material, it is built to withstand extreme combustion pressure and elevated operating temperatures common in high-horsepower 5.9L Cummins builds. The gasket includes a .067 inch compressed thickness and is sized for a 4.100 inch bore, providing an optimal seal for modified engines that demand extra strength around the cylinder head. Unlike standard composite gaskets, the MLX design uses a combination of embossed and coated layers that flex with thermal expansion while maintaining sealing integrity. This gasket is manufactured to order, ensuring precise production and fresh materials, with a lead time of approximately 2-3 weeks before shipping. It fits a wide range of Dodge D250, D350, W250, W350, and RAM 2500/3500 models from 1989 through 1998. Whether you're building a street monster or prepping for competition, this gasket delivers a factory-fit solution with upgraded durability.
