1989-93 5.9L Dodge Cummins Diesel Performance Products, Parts and Accessories

World's first Dodge pickup powered with a Cummins diesel engine. This 1988 model was built and shown at the Louisville truck show.

1989 was the start of a beautiful thing, the marrying of Dodge and Cummins.  When the Dodge-Cummins pickups came on the scene, the light-duty truck market was changed forever.  Its true that GM had diesel pickups in their line since 1978 and Ford since 1983. And that's all fine and dandy, but those who know diesels, understand the major difference we're talking about here.  The smaller Cummins' engine produced more torque than either of Ford or GM (400 vs. Ford's 345 ad GM's 246).  And with a manual transmission, the Dodge's GCW rating was 16,000 pounds, or two tons greater than its closes competitor!

And to top it off, the Cummins engine used in the Dodge lineup first went into production in late 1984 for such heavy-duty applications as combines, tractors, road graders, loaders, cranes, and crawlers.  Thus,the Cummins engine had been tested on the job for 5 years and more than 11 million miles before the first one was installed in a Dodge pickup.

Products in this section are designed to work on 1989, 1990, 1991, 1992 and 1993 model year Dodge trucks equipped with the 5.9L Dodge Cummins unless otherwise noted.
