Ford's 3/4-ton hauler receives only slight mechanical and chassis refinements. Two versions of the 7.3L turbodiesel, direct injection and indirect injection, are offered on models above 8,500 pounds GVWR. Environmentally friendly CFC-free air conditioning is offered, and standard equipment grows with the addition of side door beams, a center high-mounted stop lamp, a driver-side airbag (for under-8,500 GVWR models) and a brake shift interlock system for all automatics. A premium 40/20/40 bench seat option is added to XLT Crew- and SuperCab styles and a wide-ratio four-speed automatic transmission with overdrive accompanies the 5.0L engine.
