Dodge Ram Cummins 5.9l 6.7l diesel engine specs

Dodge Ram Cummins 5.9l 6.7l diesel engine specs have changed a lot from 1989 to 2017.  The Cummins corporation actually made the engines for the Chrysler corporation bda Dodge and Ram companies.  All these Cummins diesel engines are inline 6 cylinders.  You can find these Cummins engines in many Dodge Ram 2500, 3500, 4500 and 5500 truck models.  The original design in 1989 to 1993 started with  a 5.9l VE-Rotary pump and 12 valves.  These engine produced 160 horsepower (HP) and 400 foot pounds of torque (lb-ft).  In the next generation of 5.9l Cummins engines they would change the pump to a P-7100 from 1994-1998 but was still only 12 valves.  These Cummins engines produced from 175 to 235 HP and 440-460 lb-ft torque.  In the third generation of 5.9l Cummins engines they would replaced the pump with the VP44 model and would move to 24 valves from 1998.5  to 2002.  These Cummins engines produced 235-245 HP and 460-505 lb-ft of torque.  These Dodge Ram trucks were also the first to get a catalytic converters which were required for EPA regulations.  The last generation 5.9l Cummins engines from 2003 to 2007 used HPCR pump and 24 valves.  They have 305-325 HP and 600-650 lb-ft of torque.  Cummins made a displacement change in 2007.5 to the 6.7l Cummins diesel.  This new generation of 6.7l engines started to use a Diesel Particulate Filter (DPF) as well as a catalytic converter for new stricter EPA regulations.  The new Cummins 6.7l engine from 2007.5 to 2015 had 350-385 HP and 865 lb-ft of torque.   In 2016 Cummins broke the 900 lb-ft torque mark.  For both 2015 and 2016 Cummins had broken the torque records for any massed produced road worthy vehicle in the United States.  The 2017 6.7L Cummins has the same engine as the impressive 900 lb-ft torque of the 2015 6.7L Cummins engine in the Ram trucks.  Below is a chart from 1989 to 2107 to show the changes of HP, lb-ft, pumps and valves.  Dyeautos.com has diesel trucks for sale many of these trucks are Dodge and Ram diesels.  As a side note you can denote the 5.9l’s and 6.7l’s by the 8 digit of the VIN as a “C” or an “A,” respectfully.
