Product Description

This 6-piece fuel injector set is designed for 2003–2004.5 Dodge RAM 2500 and 3500 trucks equipped with the 5.9L Cummins diesel engine and replaces commonly referenced injector numbers including 4940589, 3949619, R8004082AC, 8004082AA, and related cross-reference numbers. These common-rail diesel injectors are designed for precise fuel metering, consistent fuel delivery, effective atomization, and reliable combustion to support stable engine performance in heavy-duty pickup truck applications. Because 2004 includes an early-production changeover, the engine CPL and original injector number should be verified before ordering.
