Fleece Performance Cheetah Turbochargers: The Drop-In Diesel Standard

When diesel truck owners talk about the gold standard in drop-in performance turbochargers, one name consistently rises to the top: Fleece Performance Engineering. Their legendary turbocharger lineup — built around the iconic Cheetah® series — has earned a reputation as a benchmark product among Cummins, Duramax, and Power Stroke enthusiasts alike. Explore the full Fleece Performance catalog to see everything this Indiana-based innovator has to offer.

What Makes the Cheetah® Different?

The Cheetah's edge comes down to what's inside. Fleece's exclusive Forged Milled Wheel (FMW) compressor wheel technology is machined in-house and paired with an Inconel turbine wheel — a combination engineered specifically to deliver faster spooling, lower exhaust gas temperatures (EGTs), and meaningful power efficiency gains over a stock unit. The result is a turbo that spools quickly like a smaller unit but opens up on the top end to push serious power.

What truly sets the Cheetah apart in the market is its stock-appearing, drop-in design. These turbochargers utilize factory housing with upgraded internals, meaning all factory systems remain intact. No expensive mounting kits, no custom fabrication — just bolt it on and go. The Cheetah series is also rated to handle up to 40 PSI of boost while supporting rear-wheel horsepower figures well into the 650+ RWHP range, making it an ideal choice whether you're towing a trailer every day or competing on the sled-pull circuit on weekends.

Coverage Across the Big Three Diesel Platforms

Fleece offers Cheetah turbochargers across a wide span of model years and engine families, including:

• Dodge/Ram Cummins — 5.9L applications dating back to 1994, and modern 6.7L VGT Holset-based units covering trucks through the 2024 model year
• GM Duramax — from the original 2001–2004 LB7 through the current L5P, including LLY, LBZ, LMM, and LML generations
• Ford Power Stroke — including the 6.0L and 6.7L platforms, with cab-and-chassis variants available for the 2017–2019 Ford 6.7L

This breadth of fitment means that regardless of which diesel platform sits under your hood, there is likely a Cheetah application purpose-built for your truck's specific turbo architecture. Fleece even offers complete turbo installation kits — including drain tube kits, oil feed lines, stud kits, and gaskets — to make the swap as straightforward as possible.

Engineering Integrity at the Core

Fleece Performance Engineering was founded in 2008 by brothers Brayden and Chase Fleece, whose hands-on development approach — testing first on their own personal trucks — translated directly into products that reflect real-world diesel demands. Today, their manufacturing facility in Pittsboro, Indiana produces turbochargers that are rigorously tested for durability under extreme conditions, from daily commutes to high-stress competition environments. The Cheetah is sold brand new with no core charge required, removing one of the most frustrating friction points of the traditional performance turbo upgrade process.
