Product Overview
Fleece Performance Cheetah® Turbocharger for 2003–2004 Dodge/Ram 5.9L Cummins
The Fleece Performance Cheetah® Turbocharger is engineered as a direct, stock-appearing replacement for the factory turbocharger on compatible 2003–2004 Dodge/Ram 2500 and Ram 3500 trucks equipped with the 5.9L Cummins diesel engine.
Unlike upgrade turbos that require an additional kit, the Cheetah® is designed to bolt directly into the factory location while offering significantly more capability than the factory unit.
Built around Fleece Performance’s exclusive 63mm Forged Milled Wheel (FMW) compressor technology and an Inconel turbine wheel, the Cheetah® is designed to deliver smooth throttle response, strong top-end power, and the distinctive sound Cheetah-series turbos are known for.
