LMM Duramax Turbochager

Upgrade your 2007.5–2010 Chevy Silverado or GMC Sierra 2500HD/3500HD with premium turbochargers designed to increase horsepower, torque, and throttle response. The factory turbo on the 6.6L LMM is a variable geometry turbocharger (VGT) that provides excellent low-end response, but after years of hard towing, the internal vanes can stick with soot, causing sluggish acceleration, high exhaust gas temperatures (EGTs), and eventual turbo failure. Whether you need an OEM-style replacement to restore factory reliability or a high-performance upgraded unit to support massive horsepower and aftermarket tuning, we have the perfect solution. Upgrading to a drop-in performance turbocharger—like a Fleece Cheetah or a Garrett Powermax—significantly improves spool times and overall engine efficiency while utilizing the factory mounting locations for an easy installation. In addition to complete turbochargers, we offer all the necessary supporting components, including billet turbo resonator delete plugs, high-flow turbo inlet manifolds, VNT actuator solenoids, and complete installation gasket kits. We supply premium turbochargers and components from trusted industry leaders like Garrett, KC Turbos, Fleece Performance, BD Diesel, and genuine GM.
