MAHLE Motorsports Cast Duramax Performance Pistons (STD)

2001-2010 GM 6.6L Duramax (.020 over)

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. 

Features: 

• Performance-oriented combustion bowl with design features intended to reduce erosion issues caused by high pressure, long duration and advanced timing. 
  
• Lower compression ratios (0.5 to 1.5 pts, or custom depending on application) allowing more flexibility for high output tuning. 
  
• Fully radiused valve pockets, where applicable to reduce drag and increased scuff resistance. 
  
• Rings, pins and clips included.
• 16.8:1 Compression
