MAHLE has released four new performance cast PowerPak piston sets for the 6.0L and 6.4L Ford Powerstroke. Developed for diesel motorsports competition, the 6.0L pistons are based off the 2004+ design, and the 6.4L pistons are based off of the MaxxForce design providing maximum strength and superior durability.
All four sets offer incredible versatility, allowing a daily driver to become a weekend warrior for drag, dyno, or pulling competitions. These castings retain the OEM steel top ring insert for the longevity of the top ring groove and are engineered with fully radius’d valve pockets to reduce stress and fatigue cracking. Also, a lower compression ratio (.5 to 1.5 points) allows more flexibility for high output tuning.
Designed with performance bowls that reduce erosion issues caused by high pressure, long duration, and advanced injection timing, and available with 0.100” deep intake and exhaust valve pockets that work with many performance aftermarket camshafts.
The 6.0L PowerPak set is cast from MAHLE’s proprietary M124 alloy and the 6.4L Powerstroke set is cast from M142 alloy. Both are designed for a 4.134″ stroke and 6.929″ rod. The CR is calculated with 0.0008” piston protrusion above deck and 0.059” head gasket thickness. As with all PowerPak piston sets, the pistons are treated with MAHLE’s proprietary GRAFAL skirt coating for reduced drag and increased scuff resistance. Heavy-duty DLC-coated tool steel wrist pins, clips, and a high-performance ring set rounds out this value-packed PowerPak.
