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

New for 2019, A thermal barrier, ceramic based coating can be applied to these pistons. The coating is durable, resistant to thermal shock, insulates the piston crown, and reduces heat transfer to increase performance. This new ceramic based piston coating paired with the Grafal skirt coating will take performance to the next level. Mahle's proprietary Grafal anti-friction skirt coating is like no other on the market. It is graphite impregnated to reduce drag. Grafal offers a unique cushioning property that absorbs harsh contact between the piston skirt and the cylinder bore.

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 application. 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.
