1990-1993 Dodge Ram Pickup: Technical Specifications

Regular-cab 150/250 trucks got a standard 3.9-liter V6 engine that produced 125 horsepower. A 170-horsepower, 5.2-liter V8 was standard on Club Cab models and the W250, and optional on most others. A 190-horsepower, 5.9-liter gasoline V8 went into 350-series Rams, and was optional in other models. The V6 and smaller V8 gained considerable horsepower in 1992, while the 5.9-liter V8 got its power hike a year later, each adopting a "Magnum" designation. The Cummins Turbodiesel six was optional in regular-cab 350-series trucks and in 250-series trucks rated above 8500-pound gross vehicle weight. Four-speed manual gearboxes were standard on 2WD regular-cab Rams with gasoline engines, on 4WD models sold outside California, and on Club Cabs. A 5-speed was available on 2WD V6 models, and standard with the Turbodiesel. Three-speed automatic was optional with sixes. A 4-speed automatic was available on 4WD gas models and 2WD models with V8s. After 1991, all manual gearboxes were 5-speed. On-demand, part-time 4WD is not for use on dry pavement, but standard automatic locking front hubs permit shift-on-the-fly between 2WD and 4WD High at up to 55 mph.
