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.

Features:

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
