2011-2016 GM Duramax 6.6L LML Compound Turbo Kits

A Compound Turbo System is a common upgrade many 2011-2016 GM 6.6L Duramax LML owners make on their rig as they deliver improved response, power, and fuel economy over your stock system. These compound systems pair a smaller turbo that provides low RPM response with a larger turbo producing more power at high RPMs. The result – two powerful turbochargers that simultaneously operate as one throughout the entire RPM range, helping you unlock the full potential out of your Sierra/Silverado 2500/3500. Here at Alligator Performance, we carry a selection of these compound turbo systems so we're sure you'll find exactly what you need for your custom build!
