Unlock true diesel dominance in your 2003-2004 Dodge Ram 2500/3500 with the Fleece Performance Cheetah Turbocharger for the 5.9L Cummins. This is more than a bolt-on upgrade—it’s a carefully engineered, drop-in replacement that preserves a stock appearance while delivering dramatically increased power, reliability, and driveability.

Key reasons drivers choose the Cheetah Turbo for the 5.9L Cummins

• 63mm FMW compressor wheel—a purpose-built, exclusive design that delivers rapid spool with impressive top-end power, translating to quicker response on roll-on and better acceleration across the RPM range.
• Inconel turbine wheel—high-heat, durable material engineered to withstand the stresses of boosted boost and extended hard pulls, preserving performance and longevity.
• Wastegate preset to 40 psi—precise, consistent boost control that helps you avoid bog or over-boost while maximizing usable power.
• No core charge—simplified ownership: bolt it on and drive, without the hassle of returning a core or chasing rebuild parts.
• Up to 650 RWHP capability with appropriate supporting modifications, giving a clear scale of the horsepower you can unlock beyond stock.
• Stock-appearing, drop-in replacement—reliability and stealthy looks mean you stay under the radar while gaining real performance.
• 1-year limited parts warranty—built-in protection for peace of mind as you explore higher-performance driving.
• Patented technology—protected design (US Patent D1066420) that underpins the Cheetah’s proven performance and durability.

Designed for your truck and its potential

The Cheetah Turbo is engineered to fit 2003-2004 Ram 2500/3500 trucks with the 5.9L 24V Cummins engine. It’s a true drop-in upgrade that doesn’t require an expensive upgrade kit—simply bolt on and go. Expect smoother throttle response, stronger mid-range torque, and a compelling top-end pull that makes highway passing and towing feel more confident.

Fitment and installation notes

To confirm proper fitment for your truck, verify that the tenth digit of your VIN is a 3 or 4. If the tenth digit is a 5 or higher, you’ll need the alternate part FPE-351-0407. This part is protected by the same proven technology and is designed to match the same performance expectations.

Practical use cases and real-world benefits

• Daily driving with enhanced throttle response—enjoy immediate acceleration and improved driveability in everyday commutes and versatile duty cycles.
• Tow-grade capability—increased boost and robust mid-range torque help with uphill climbs, trailers, and heavy loads where stock boost may stumble.
• Weekend power builds—for enthusiasts who want a high-performance platform with room to scale, the Cheetah lays the groundwork for big-tune potential.

Performance philosophy and how it compares

Unlike generic aftermarket turbos, the Fleece Performance Cheetah combines a purpose-built 63mm FMW compressor wheel with an inconel turbine wheel to deliver a balanced blend of quick response and endurance under high-boost conditions. The 40 psi wastegate setting provides predictable, safe boost control, enabling you to chase real-world horsepower gains (up to approximately 650 RWHP) without sacrificing reliability or daily usability.

Maintenance, tips, and care

To maximize the Cheetah’s lifespan and performance, pair this turbo with appropriate supporting modifications (fuel system, intercooling, exhaust, and intake sizing as needed). Regular inspections of charge piping, intercooler connections, and exhaust hardware will help you maintain consistent boost and prevent leaks that can sap performance. Rely on the included warranty for protection as you explore higher-performance driving scenarios.
