6.7L Diesel PowerPak Piston Kit

Mahle Motorsport now offers a comprehensive line of Dodge Cummins diesel performance pistons with the addition of its 6.7L Diesel PowerPak Piston Kit (part #197850313) developed for diesel drag race and pulling applications for the Dodge Cummins 6.7L.

This PowerPak kit includes German steel pins and a stainless steel Nitride ring set – 1/16″, 1/16″ and 3/16″ that feature Mahle’s exclusive M142P alloy, high temperature and strength and low expansion characteristics.

The pistons have a hard anodized top ring groove for added durability and increased longevity, and GRAFAL® coating for reduced drag, scuffing friction and cylinder bore wear.

This kit offers the choice of a thermal barrier crown coating.

The pistons are designed with a modified bowl that mimics the design used in industrial QSB applications, reducing erosion issues caused by high pressure, long duration or advanced injection timing.

The pistons feature oversized valve pockets that are 0.200” deep allowing up to 1.500” intake and a 1.450” exhaust valve diameter, fully radiused valve pockets reduce stress and fatigue cracking and with a 2.722” compression height the pistons allow for 0.010” deck machining while retaining the stock piston protrusion.
