MAHLE Motorsports Duramax Performance Cast Piston Kit

Rated up to 1000HP

Fits 2001-2010 6.6L Duramax

Designed for street/strip or pulling trucks making 400-1000HP that still get used as a daily driver or work truck. Machined from OE castings (retaining the cast iron ring insert) to give the same drivability and longevity of a replacement piston with additional strength necessary for modified engines. These Pistons are built for customers looking to get 100,000+ miles on a high horsepower applicaton. Unlike some of the higher HP forged pistons which need to be replaced every 20,000 to 30,000 miles, these Mahle Pistons are built to last.


  • Performance-oriented combustion bowl with design features intended to reduce erosion issues caused by high pressure, long duration and advanced timing. 
  • De-Lipped and strengthened
  • Lower compression ratios allowing more flexibility for high output tuning. 
  • Fully radiused valve pockets, where applicable to reduce drag and increased scuff resistance. 
  • Includes Rings, Wrist Pins and Clips
