Fits: 2001 thru 2016 Chevy Silverado/GMC Sierra 2500HD/3500 LB7/LLY/LBZ/LMM/LML Duramax Diesel

Designed for engines 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.
