These Mahle Motorsports pistons are the perfect stock replacement option for Duramax guys looking to make up to 900HP. Theses delipped pistons disperse heat much better then stock and the coated skirts ensure excellent skirt wear and oil control. We install these pistons in many of our entry level builds where customers have small to medium injector and turbo upgrades.
