In the late 1980s, Dodge Truck sales made a dramatic comeback when Chrysler partnered with Cummins, offering a 5.9L inline six-cylinder, 12-valve Cummins engine option. I test drove one of the earliest models with a three-speed A727 Torqueflite transmission. What a difference that powertrain made in contrast to gasoline engines of the era! Since that time, the 12- and 24-valve Cummins ISB and 6.7L options have made Dodge and Ram trucks a major contender at hauling and performance. The 4WD Mechanix Magazine fleet vehicles include a 2005 Ram 3500 4WD with 5.9L Cummins 24-valve engine, featured in projects and for towing chores. Dodge-Ram Cummins owners will find an enthusiastic community at this forum!—Moses Ludel

Upgrades like the Mopar running boards or re-valving the 48RE automatic transmission for longevity are some of the details available at the magazine site. Routine maintenance and recommended lubricants, coolant, fluids and filters for the Cummins can be found at the magazine's Dodge-Ram Truck Workshop!
