Restore factory fuel delivery performance and dependable diesel operation with the genuine Mopar R8310748AA Remanufactured Fuel Injector Set for 2003-2004 Dodge Ram trucks equipped with the 5.9L Cummins common rail diesel engine. This complete OEM remanufactured injector kit includes six professionally remanufactured injectors engineered to meet or exceed original factory specifications for fuel atomization, injector balance, fuel economy, and engine reliability.
The Mopar R8310748AA injector set is specifically designed for early common rail 5.9L Cummins applications found in 2003-2004 Ram 2500 and Ram 3500 trucks. Each injector is rebuilt using genuine OEM-quality internal components including updated nozzles, control valves, and solenoids to provide precise fuel delivery and long-term durability under demanding diesel operating conditions.
Replacing worn or failing injectors can help eliminate excessive smoke, rough idle, injector knock, hard starts, poor throttle response, fuel contamination issues, and reduced fuel economy. Genuine Mopar remanufactured injectors are calibrated to OEM Cummins standards for proper cylinder balance and consistent performance.
This complete 6-pack injector kit is ideal for full injector replacement service on high-mileage 5.9L Cummins engines and helps restore smooth operation and reliable towing performance. Unlike lower-quality aftermarket injectors, genuine Mopar remanufactured injectors maintain factory spray patterns and proper ECM communication.
