When You Are Done Taking Chances On Leaks

If you're ready to stop dealing with weak head gaskets and finally seal up your 5.9L Cummins the right way, the Cometic C5855-072 MLX Cylinder Head Gasket is the upgrade you've been looking for. Whether your truck is a weekend workhorse or tuned to lay down serious power, this gasket is built to keep it all contained under pressure. The .072-inch compressed thickness adds sealing strength without sacrificing fitment, and it works especially well for engines that have seen years of use. It’s the perfect match for your 1998–2002 Dodge RAM 2500 or 3500, whether you’re doing a top-end rebuild or prepping for high-boost performance. With five layers of stainless steel and reinforced sealing surfaces like armor-clad and graphite, you can trust this gasket to hold its ground. You also won’t need to re-torque it once installed, which means less downtime and more peace of mind. If you're serious about doing things once and doing them right, this gasket is your go-to solution.

Designed To Deliver Strength Where It Matters Most

The Cometic C5855-072 MLX Cylinder Head Gasket is engineered to provide consistent and durable sealing for the 5.9L 12-valve Cummins engine found in 1998–2002 Dodge RAM 2500 and 3500 trucks. Featuring a 4.100-inch round bore and a .072-inch compressed thickness, this gasket is optimized to handle high combustion pressure while maintaining a proper seal across the head and block surfaces. Its five-layer multi-layered steel (MLS) construction includes a galvanized steel core for added rigidity and structure under clamping loads. The outer layers are coated with a high-temperature polymer and reinforced with armor-clad and graphite compounds to seal irregular or worn mating surfaces. This construction helps reduce bore distortion and prevent blowouts even under heavy-duty use and high boost scenarios. The gasket’s design eliminates the need for re-torque, which improves installation efficiency and long-term reliability. Whether you're building for reliability, performance, or both, this gasket provides the sealing integrity demanded by serious diesel builds.
