Chronology
Predecessor Ford F-Series seventh generation (1980–1986)
Successor Ford F-Series ninth generation (1992–1996)

The eighth generation of the Ford F-Series is a line of pickup trucks and medium-duty commercial trucks produced by Ford from 1986 to 1991. While the 1980 body and chassis was carried over to the new model, the 1987 model was more streamlined, and maintenance items were made simpler. The Exterior was facelifted with new composite head lamps (showing it was the same model from 1980 with minor updates. Inside, the interior was given a complete redesign. Rear antilock brakes were now standard, the first truck to boast this. For the first time, all models were produced with Styleside beds; the Flareside bed was discontinued except for a small number of early 1987 models using leftover 1986 beds with new circular fenders.

Trims

Ford F-250 Utility service truck

For 1990, a "Nite" trim package was introduced. It included all blacked-out exterior trim, either a pink or blue/purple stripe, and a "Nite" decal on the sides of the cargo box.

Models

Ford F-350 U-Haul truck in Hampton, VA.

The models are:

The F-Super Duty (as the fender emblems stated), F-250, F-250HD, and F-350 chassis cab models appeared from 1987 to 1997. The F-Super Duty was basically a F-450 built as an "incomplete vehicle" (chassis cab) due to the fact that there was no bed installed and an aftermarket bed (specific to its future use) was added after the truck's initial build date. Because the F-250,F-250HD, F-350, and F-Super Duty were only built and produced as Chassis cab models, owners would eventually convert the models to pickup trucks, but General Pacheco, Argentina and São Bernardo do Campo, Brazil assemblies where the only places F-250, F250 HD, and F-350 were built and sold as pickup trucks models (they were shipped to the United States as imports). The F-Super Duty came with dual fuel tanks with a dash-mounted toggle switch to switch between each tank while using only the one fuel gauge. It came with a PTO (Power Take-Off) used to power attachments (like winches or a dump bed) from the transmission. They were rated at about 15,000 lb (6,800 kg) GVWR (Gross Vehicle Weight Rating). They came with either the standard 7.5 L (460 CID) gas V8 or the optional 7.3 L (444 CID) diesel V8. All wheels were 10-lug with DRW (Dual Rear Wheels). Also, the parking brake is mounted on the tail of the transmission. This model should not be confused with the later "Super Duty" commercial line of trucks starting with the 1999 model year.

Powertrain and Chassis

In a move to further update the F-Series engine lineup, the 4.9 L inline-6 was converted to fuel injection for 1987. A year later, Ford F-150 became the first pickup truck manufacturer to sell a non-carbureted engine lineup as the 5.8 L V8 and 7.5 L V8 also gained fuel injection(the 5.0 L V8 had gained fuel injection as an option for 1985 and was made standard in 1986) . For 1988, the diesel V8 from International (Navistar) was enlarged to from 420 to 444 cubic inches; this allowed for an increase to 180 hp (130 kW). and 365 ft·lbf (495 N·m). of torque.

While the dated 3-speed manual transmission was discontinued, much of the rest of the transmission lineup carried over from the 1980-1986 trucks. In 1988 the five speed ZF S5-42 replaced the Borg-Warner T19 in F-250 and F-350 models. For the F-150, while the heavier-duty Borg-Warner T18 4-speed manual remained available, the Mazda-built M5OD 5-speed manual was added to the model lineup. Also the only transmission available on supercab models was a 5 speed or 4 speed manual (while regular cab models were equipped with either a manual or automatic transmission).

Four-wheel-drive improvements included the addition of automatic locking hubs for the F-150 in 1989. Models with the 5.0L V8 also had an option of a "Touch Drive" electronic transfer case.

Starting in 1980 (up to the end of the 9th generation F-series), Ford offered a four-wheel-drive swing arm independent front suspension called Twin Traction Beam, or TTB. Based on its two wheel drive twin I-beam suspension from 1965, Ford mounted a Dana 44 differential in the driver-side (front) axle beam and transmitted torque to the passenger-side wheel with a double U-jointed axleshaft. Radius arms and coil springs were still used on the F-150, while the four-wheel-drive F-250 and F-350 got leaf springs. The F-250 received TTB Dana 50 axles and the F-350 got a solid axle Dana 60.
