Fleece Performance 11-16 Chevrolet Duramax 6.6L (LML) 63mm Billet VNT Cheetah Turbocharger

Starting with a 63mm billet compressor wheel, this Fleece Performance Cheetah turbocharger is built for your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, and the GMC Sierra equivalents. This turbocharger is designed to replace the factory Variable Geometry Turbo (VGT) with an updated design that handles more airflow. The billet wheel construction means it's lighter and stronger than cast wheels, allowing for quicker spool-up and better response.

The VNT (Variable Nozzle Turbine) design is key here. Unlike fixed-geometry turbos, the VNT system adjusts the turbine housing's effective area on the fly. This allows the turbo to behave like a smaller one at low RPMs for quick throttle response and then open up like a larger turbo at high RPMs to prevent backpressure and maximize power. This updated design helps reduce exhaust gas temperatures (EGTs) under load, which is crucial for keeping your Duramax 6.6L LML engine running strong, especially if you tow or haul heavy loads. The Cheetah series from Fleece is well-known for its ability to support significant power increases over stock while maintaining drivability.

This turbocharger is a direct replacement for your factory unit, simplifying the installation process. It's a solid option if you're looking to upgrade your truck's performance and towing capability. Ensure you have the necessary supporting modifications and tuning in place to take full advantage of this turbo's potential. Always refer to the manufacturer's installation instructions for specific details and recommended procedures.
