A Drop-In Turbo That Delivers Real Power

If you’re looking to wake up your 2001 to 2004 Duramax LB7 without diving into a full custom setup, the Fleece FPE-LB7-63 Cheetah Turbocharger is the upgrade that gets it done right. This 63mm billet turbo is a true drop-in replacement, designed to bolt right into the factory location without modifications. It’s built around a precision-machined billet compressor wheel and a high-flow Inconel turbine wheel, giving you quicker spool-up and better airflow across the board. Whether you're towing heavy, daily driving, or looking for more performance on the weekend, this turbo will get your LB7 up to 625 rear-wheel horsepower with the right supporting mods—all while keeping street drivability intact.

Engineered for Simplicity, Built for Strength

What makes this turbo really shine is how much performance you gain without sacrificing reliability or adding complexity. There’s no core charge, and it even comes with an installation kit and a high-flow intake horn, so you have everything you need to get it installed and on the road. The Inconel turbine wheel holds up under heat and stress, making it ideal for tuned trucks or trucks that see regular hard use. It's compatible with federal emissions-equipped vehicles, but not for California trucks, so it’s important to check your vehicle's compliance. For LB7 owners looking for a balance of power, reliability, and easy installation, the Fleece 63mm Cheetah is hard to beat. It’s a serious upgrade that fits like it belongs there.
