Put a set of MAHLE Motorsports 9300362 Forged Aluminum Race Pistons in your 2001-2010 GM 6.6L Duramax. These custom forged diesel pistons are best suited for dedicated race vehicles. Although these performance forged pistons are stronger, the lack of a steel top ring groove in the forging will result in a limited lifecycle for street use applications. Strength and design flexibility make the performance forged piston a favorite for competition only applications. 


  • CNC machined from MAHLE's exclusive M142S alloy chosen for its good high-temp strength and low expansion characteristics. 
  • Performance bowls with design features intended to reduce erosion issues caused by high pressure, long duration, and advanced injection timing.
  • Multiple options - You specify compression ratios and pocket/bowl configuration to get the best pistons for your application
  • Fully radiused valve pockets (where applicable) to reduce stress and fatigue cracking
  • Hard anodized top ring groove fro added durability and increased longevity 
  • Grafal coated skirts for reduced drag and increased scuff resistance
