Premium Mahle Head Gasket for 5.9L Cummins

If you’re rebuilding your 5.9L Cummins or refreshing the top end after decking the block or head, the Mahle 1.28MM Head Gasket is the right part to finish the job with confidence. Designed specifically for 2003–2007 Dodge Ram 2500 and 3500 trucks, this gasket offers a slightly thicker profile—perfect for engines that have had surface material removed during machining and need the extra spacing to maintain proper compression and piston-to-head clearance. Mahle is one of those names that diesel builders trust, and for good reason. This gasket is built from a multi-layer steel design, giving it the strength and durability needed to hold up under the extreme cylinder pressures and temperatures common in a turbocharged diesel. Whether you’re running stock power or adding a few upgrades, this gasket is engineered to keep everything sealed and running smooth.

Designed for a Precise Fit

Fitment is spot on, so there’s no wrestling it into place or worrying about misalignment. It goes on clean, seals tight, and holds strong—exactly what you want from a head gasket, especially if you’re putting in the time to do things right the first time. If you’ve already gone through the effort of decking or surfacing the head, this 1.28mm version ensures you’re not tightening things down too much and throwing off your build’s balance. It’s a small detail, but one that makes a big difference in long-term engine reliability and performance.

Fits: 2003, 2004, 2005, 2006, 2007 Ram 5.9L Cummins
