Dodge Ram trucks continue to maintain a well-deserved reputation for being hard working, durable, and above all, ruggedly powerful. When you add a legendary Cummins diesel engine to the picture, the result is an outstanding combination of performance and dependability that sets the Ram pickup apart from the other trucks in its class.

This is an in depth look at the many enhancements to the diesel power plant, including the most obvious changes such as the new 24 valve cylinder head and valve train, and the Bosch VP44 fuel injection pump.  Also covered are new items on the lower end of the engine and its lubrication system, the new fuel system, and intake and exhaust systems.
