Diesel drag racing has come a long way in the last couple of decades. From entry-level bolt-ons, to full-on engine builds, nobody is glossing over the booming diesel market anymore — including our friends at MAHLE Motorsports.
MAHLE Motorsport Expands Dodge Cummins Line Introduces 6.7L Diesel PowerPak Piston Kit
Fletcher, NC, (May 20, 2019) – MAHLE Motorsport now offers the market’s most comprehensive line of Dodge Cummins diesel performance pistons with the addition of its 6.7L Diesel PowerPak Piston Kit (part #197850313). This kit was developed for diesel drag race and pulling applications for the Dodge Cummins 6.7L.
Featuring MAHLE’s exclusive M142P alloy because of its high temperature and strength and low expansion characteristics, this PowerPak kit includes German steel pins and a stainless steel Nitride ring set – 1/16″, 1/16″ and 3/16″. The pistons feature a hard anodized top ring groove for added durability and increased longevity, and GRAFAL® coating for reduced drag, scuffing friction and cylinder bore wear. For this kit, MAHLE also 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. This design reduces 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. With a 2.722” compression height the pistons allow for 0.010” deck machining while retaining the stock piston protrusion.
