What year is a 1st gen Dodge diesel?

The first generation of Dodge diesel trucks was introduced in 1989. These trucks were powered by a Cummins 5.9-liter inline six-cylinder diesel engine, which was a significant upgrade from the previous gasoline-powered engines used in Dodge trucks.


The Rise of Dodge Diesel Trucks


In the late 1980s, Dodge recognized the growing demand for more powerful and fuel-efficient trucks, particularly in the commercial and agricultural sectors. The introduction of the Cummins diesel engine in Dodge trucks was a game-changer, as it provided significantly more torque and towing capacity compared to the gasoline engines that had been the standard in the industry.


The first-generation Dodge diesel trucks, often referred to as the "Cummins Dodge," were available in various configurations, including the full-size Ram 150, 250, and 350 models. These trucks were known for their rugged design, impressive hauling capabilities, and reliable performance, which made them popular among farmers, construction workers, and other heavy-duty users.
