Designed For Reliability In High Stress Builds

The Cometic C5589-053 MLX Cylinder Head Gasket is engineered to meet the rigorous demands of 6.0L Powerstroke engines running in 2003–2007 Ford F250 and F350 trucks. Built with five layers of stainless steel, this MLX gasket structure delivers excellent sealing under high combustion pressures while maintaining its form during repeated heat cycles. It features a .053 inch compressed thickness and a 96mm bore with valve pocketing to accommodate the combustion chamber shape and ensure a tight, efficient seal. The gasket is designed for heads with 18mm dowels, making it a precise fit for specific cylinder head configurations common to early 6.0L engines. The advanced material compounds used, including armor-clad and graphite, help conform to less-than-perfect surface finishes, reducing the risk of micro leaks or blowouts. This makes it especially valuable for performance builds, towing applications, or any engine under high stress. If you're assembling a motor that you want to last, using a gasket like this one provides a reliable foundation you can count on.
