DESCRIPTION
The Cummins 4B 3.9 Long Block Engine is a powerful and reliable engine commonly found in medium-duty trucks, construction equipment, and agricultural machinery. Part number DR6375RX denotes a remanufactured long block engine that has been rebuilt to strict OEM specifications using genuine Cummins parts, ensuring optimal performance and longevity. With a displacement of 3.9 liters and four cylinders, this engine delivers up to 140 horsepower and 420 lb-ft of torque, making it an ideal choice for applications that demand high power output and efficiency. The long block configuration includes the cylinder block, cylinder head assembly, camshaft, valves, pistons, connecting rods, and oil pump - everything needed for a complete engine rebuild except for external components such as the turbocharger or fuel system. This allows for quicker installation with less downtime compared to a full engine replacement while still providing reliable performance that Cummins engines are known for.
