The K2XX platform made its way to GM's HD series trucks for the 2014 model year. With it came major upgrades inside, outside, and most importantly, under the hood. The base engine became a 6.0L LS-based V8 producing up to 360 horsepower. For 2014-2016, the 6.6L LML Duramax was the line-topping diesel, and it was superseded in 2017 by the L5P, which provided 910 lb/ft of torque in stock form. No matter how you put your HD truck to use, we have the parts to make it perform better.
