2017 - 2019 Chevy/GMC 6.6L L5P Duramax

The 2017 Duramax model year marked a significant leap forward in GM’s diesel lineup. Released in 2017, this engine came out strong with 445 horsepower, establishing itself as a class leader. Despite rumors of a potential displacement increase, GM stuck with the 6.6L configuration, focusing instead on overhauling key engine components and boosting overall durability.

The 2017 - 2019 Duramax engine received a number of critical upgrades, from a stronger block and crankshaft to reinforced rods and remelted pistons. The fuel system was redesigned for more efficient delivery, while the camshaft profile was adjusted for optimized performance. Even the transmission saw improvements, with the revised Allison 1000 transmission built to handle the additional power.

Not to mention, the hood scoop on the 2017 - 2019 Chevy Duramax and 2017 - 2019 GMC Duramax is fully functional, increasing airflow by 60% and ensuring the engine runs cooler even under heavy loads. With these factory upgrades, the L5P Duramax is primed for additional aftermarket enhancements that can take your truck to the next level.
