MAHLE Motorsports Cast Duramax Performance Pistons (STD)
2001-2010 GM 6.6L Duramax (Standard Size)
Performance Cast Pistons
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.
