This final generation received a facelift in October 1980 when the D series was rebadged as the Dodge Ram pickup around when Lee Iacocca took charge of the ailing Chrysler Corporation. Such things including an embossed "DODGE RAM" name on the tailgate along with other obvious changes like the grille and hood, the taillights, and the entire interior. More subtle was the addition of a "shoulder" line reminiscent of the GM competition. Beginning in 1982, even more corrosion-resistant steel was used in the construction of the trucks. This body style continued until 1993 and many of these vehicles are still on the road. Many body panels are interchangeable for all models from 1971 to 1993, so it is not uncommon to see a "hybrid" with, as an example, a 1978 grille mounted with a 1974 hood and a 1991 cab. Sometimes the bed is swapped with a moving truck style box for models like these. In most jurisdictions, the year is dictated by the year of the truck's chassis regardless of the body which has been bolted to it. Also kept was the narrow Utiline bed that dated back to the 1940s; this was dropped in 1985. Throttle-body injection was introduced in 1988.
A narrower range of engines was offered: the base power plant was the 225 cu in (3.7 L) slant-6, now with top-fed hydraulic tappets, and the 318 cu in (5.2 L) and 360 cu in (5.9 L) LA-series V8s. The slant-6 was supplanted by the 3.9 L (237 cu in) V6 for 1988; in 1992 it and the V8s became Magnum engines. The 6BT 5.9 L (360 cu in) 12-Valve Cummins B-series diesel engine became an option in 1989.
Sales were good during the Sweptline era and into the late 1970s. A combination of stagnant styling that was nearly two decades old plus brand loyalty primarily to Chevrolet and Ford during the 1980s and 1990s reduced sales volume for the first-generation Dodge Ram. A wholly new Dodge Ram was released for the 1994 model year.
