The seventh Ford F-Series was a line of pickup trucks and medium-duty commercial trucks produced from 1979 to 1986. For the first time since 1965, the pickup trucks were based upon a completely new chassis and body. Distinguished by its squarer look, sharper lines and flatter panels, the trucks were designed with improved fuel efficiency in mind; to this end, Ford added its new AOD automatic overdrive (four-speed) transmission as an option on light-duty models. A 4 speed manual and 3 speed C6 automatic transmission were retained from previous years. To increase longevity, Ford increased the use of galvanized body panels to fight corrosion.[citation needed] Pickup trucks were available in three body styles: regular cab, SuperCab extended cab or crew cab with two bed lengths. Dual rear wheels were a new option on F-350 pickup models. The crew cab trucks were very large, stretching nearly 20 feet long with an 8 foot bed. These trucks are considered amongst enthusiasts to be the last generation of great trucks built by Ford and are now beginning to become popular amongst restorers as the models have just reached classic car status. They are typically considered to be the last of the "classic" Ford trucks, due to the fact it had features such glass headlights, separate turn signals, stamped "FORD" lettered tailgates and analog instrumentation.

Along with the body and chassis upgrades, Ford made several changes to the branding of the F-Series over this generation. In 1982, the upscale Ranger trim was discontinued to create the nameplate for the company's all-new compact pickup that replaced the Mazda-built Courier. Largely superseded by the F-150, the F-100 was discontinued after the 1983 model year. In Mexico, there is an "F-200" which was introduced in 1976; this variant remained until 1991.

Design History and Features[edit]

In 1979, Ford debuted a brand new, redesigned pickup truck, aimed at being tough while getting better fuel economy than it's previous generation. However, drastic measures were taken in reducing weight, and because of this, severely weakened frame rails on 1980-1981 trucks, causing them to bend or buckle under load. 1980–81 trucks have a plain grille with "FORD" spelled across the front of the hood in chrome lettering, similar to the 1978-1979 models of the previous generation.

The 1982 model year was marked by a slight cosmetic change: 1982–86 models had the "FORD" letters removed, and a Ford oval placed in the center of the grille, with less vertical bars in the grille itself. This made the 1982 the first model year to feature a blue oval on the front, something that has been on every model that followed it, with the exception of the 2010-present F-150 SVT Raptor.[2] The frame was thickened up and the trucks became heavier for 1982, but these changes proved to be tough enough as this frame was used all the way up to 1997, when the F-series was once again redesigned.

Introduced for 1980 models, an optional resettable trip meter was installed on speedometers and the mileage counter was moved to the top of the speedometer as part of the optional Sport instrumentation Group. The Sports instrumentation Group also included the optional Tachometer in the center of the cluster, as well as oil and ammeter gauges. [3] In 1984, the body moulding and interior trim were updated for 1985 models. In 1985-1986 models, the upper accent mouldings were changed and are different than previous years being below the front marker. For 1985, the rear tailgate moulding on XLT models was updated and previewed the design of the 1987 model. This molding has become increasingly rare and fetches a high price. A cargo light was available as an option and was included in the Light Group option package.[4] A Combination Stop/cargo lamp was not required until September 1st, 1993 for the 1994 year model.[5]


Color choices varied with a choice of 17 colors, and came in everything from two-tone to solid colors, clear coated and non clear coated.

Various standard equipment included interesting features such as a coat hook on the drivers side, AM radio (AM/FM and AM/FM Cassette was optional), scuff plates and vent windows. In the glove department, the back of the door featured coin slots and cup depressions to hold cups and to set your foot on, similarly to a food tray on a train.

Special Order Equipment[edit]

For 1985, various special order equipment was offered on all F-150, 250 and 350 models. These are listed below with their respective descriptions.


  • Batteries: F-150, 250, and 350 buyers desiring a battery with a higher reserve capacity to meet the unusual electrical demands imposed by add-on electrical accessories or other job-related operating conditions, can choose from Motorcraft 75-amp maintenance-free or Gould 90-amp maintenance free batteries.
  • Alternator: To meet all higher-than-normal electrical demands of F-150/250/350 vehicles to be operated under especially strenuous conditions or equipped with power draining accessories, special 70- and 100-amp Motorcraft alternators with transistorized regulators can be ordered.
  • Radio Interference Suppression, Extended: Recommended when the vehicle is to be equipped with a mobile two-way radio, as it reduces ignition noise for clearer communication. Includes the basic standard components plus accessory circuits.
  • Drain Fill Plugs, Magnetic: These special drain plugs contain a permanent magnet which attracts all metal particles that can result from wear during normal operation. These particles can cause severe internal damage or excessive wear. Available for all engine oil drain plugs and selected axle/transmission applications.
  • Engine, for LPG Conversion: Customers desiring LPG (Propane) instead of conventional gasoline will want to order this Special Order option which prepares the 4.9L (300-CID) I-6 engine for popance operation. This engine is specifically engineered to burn gaseous fuel and includes numerous special components for that purpose. Installation of an LPG fuel/carburetion system is the buyers responsibility and must be accomplished within 90 days or 500 miles (whichever comes first) or the warranty is voided.
  • Hood Release, Inside Locking: This security helps protect against theft by making it difficult for a thief to gain access to the engine compartment. A thief cannot simply reach into the drivers compartment and pop open the hood using the standard inside hood release. The hood release can be activated only after being unlocked with the door key. This item is included in the Security Lock Group which is also available on all F-Series pickup models.
  • Windshield Wipers, Interval: Through Special Order, F-Series pickup buyers can take advantage of the convenience of interval windshield wipers without having to order the complete Convenience Group. By Allowing the driver to select an interval from approximately one to 12 seconds for intermittent sweeps of the wipers, interval wipers can be the ideal feature for driving in a light rain or road spray.
  • Hand Throttle: Locking and non-locking types are available to allow control of engine rpm from dashboard. Locking type is especially useful when the trucks engine is used to drive an accessory unit with high power demands, such as a winch or compressor. Throttle can be set part-way open while the driver is outside of the cab doing other jobs. Available on all models with the 4.9L and 5.8L engines. Not available with speed control or engine usage indicator.
  • Engine Usage Indicator: Hobbs Hour Meter Engine Usage indicator records actual engine hours of operation-whether idling or on road. Essential for construction contractors or fleet operators who base maintenance intervals on running time rather than mileage.
  • Mirrors, Dual-Head: An expanded field of vision to the rear and both sides of the truck is available by ordering these dual-head mirrors. Each of the western-type mirror frames holds two 6x6-inch mirrors-a flat one which provides a standard rear view with objects in proper perspective and a convex one which offers a panoramic view to eliminate blind spots. Especially helpful for trailer towing.
  • Windshield, Tinted: With this Special Order option, tinted glass can be ordered for the windshield only, instead of all the vehicles windows. The tinted windshield offers the benefit of reduced glare for the driver on bright, sunny days, plus it costs less than Tinted Glass, Complete option-especially on crew cab or SuperCab models.
  • Cargo Lamp: Illuminates area for more convenient nighttime loading and unloading. Included with Light Group.
  • Stabilizer Bar, Front: Offers improved handling on F-250/350 4x2 models. Exerts stress between the front wheels to increase vehicle stability and minimize sway, especially under heavy loads or rough terrain. Available with gasoline engines only.
  • Gas Cap, Locking: This Special Order option is offered specifically for the buyer who would like to order an F-Series pickup equipped with a locking gas cap to help safeguard the vehicles fuel tank, but does not wish to spend the extra money needed to purchase the entire Security Lock Group. This option allows him to order it with the vehicle, rather than having to go out and buy one separately after the vehicle is in service.
  • Axles, Rear: 8200-Pound Limited Slip; Offers the F-350 Dual-Rear Wheel Regular Chassis Cab 4x2 buyer with improved traction characteristics of a Limited-Slip differential. The Limited-Slip differential automatically transfers most of the driving power from the drive wheel with the least traction to the drive wheel with the most traction. Helps prevent vehicle from becoming stuck in mud, sand, ice and snow. This axle can be ordered with a 3.54, 3.73 or 4.10 ratio. Wide Track-approximately seven to nine inches wider than the standard axle, this special axle allows F-350 dual-rear-wheel Chassis Cab buyers to install special bodies (such as the popular rescue wagon) that are significantly larger than would otherwise be possible.

Trim[edit]

This generation saw two different sets of trim levels:

For 1980 and 1981, there was:

  • Custom- Base model, usually equipped with manual locks/windows, color-keyed vinyl seat and dashboard, and black rubber floor mat. However, a Custom trim truck could still share some of the same options as the higher Ranger-Ranger Lariat trim trucks. A steering wheel cover and Ford logo above the radio was optional. Chrome door handles outside the cab to hoist the buyer up and into the cab were also optional. On trucks without air conditioning, vents were not installed into the dashboard, giving the driver only two choices for air direction - "Defrost" and "Heat", with "Heat" on a non-A/C truck being the equivalent of "Floor" on a truck with A/C. The lack of vents on the dashboard does have an advantage, as it leaves a lot of room for the installation of aftermarket gauges.
  • Ranger- Intermediate trim that added a color-keyed floor mat, chrome trim on the door panels,and Rosewood dash and horn pad trim.
  • Ranger XLT- A step up from the Ranger that added unique seat trim, a color-keyed headliner, color-keyed carpeting, aluminum tailgate trim and full floor to roof trim moldings behind the seat. Also included pinstriping if ordered, synthetic wood, cloth seats and various other interior options.
  • Ranger Lariat- a step above the Ranger XLT that added a plusher interior, and Rosewood Trim on the door panels that matched the Rosewood trim on the dash. Ranger Lariats also featured special "Lariat" emblems on the cab, as well as special Ranger Lariat script above the radio.
  • Explorer- a limited edition options and trim group with year-specific stripes unique to the Explorer. offered as Explorer Package A, B, C, or D. Explorer Package A was the most basic, similar to the Custom, while the Explorer Package D was the highest level, much like the Ranger Lariat.[6]

For 1982–1986:

  • Base – Basically the same as the Custom of the previous years.
  • XL – replaced the intermediate Ranger trim for 1982 as the Ranger name would be used for Ford's new compact truck.
  • XLS- a new trim level that featured a blacked-out grille, bumpers, headlight bezels, and windshield trim. It also featured a stripe graphics package and black and silver dash trim. Available exterior colors were red, silver, and black.
  • XLT Lariat- featured floor carpeting, color-keyed headliner, a standard chrome grille, and optional power windows/door locks. 1984 saw the last year for woodgrain trim on the door panels as 1985–1986 models had a carpeted section applied to the door panels. In 1985 the tailgate trim was changed to a "flat" full width aluminum with a red "reflector" towards the bottom with chrome FORD letters.
  • Explorer a limited edition options and trim group with optional year specific stripes unique to the Explorer– The Explorer trim line (1968–1986) was dropped for the 1987 models to introduce the Ford Explorer SUV in 1991. Explorer packages changed every year,and were only offered for a limited time each model year.
  • Eddie Bauer-introduced for 1985, an outdoors-themed interior trim package with two-tone exterior paint. Originally only offered on the Bronco and Bronco II, the Eddie Bauer trim would eventually make its way to the F-Series line-up in 1995.

Powertrain[edit]

The seventh-generation F-Series marked a major transition in the powertrains used by the pickup line. As before, the standard engine was a carbureted 300 cubic-inch inline-6. For 1982, this was supplemented by a 3.8 L V6 borrowed from the Fox platform; it was dropped after 1983 as the result of slow sales. The standard V8 remained the 302 Windsor V8. To further boost fuel efficiency, a downsized 255 cubic-inch version of the 302 Windsor V8 was made an option; it proved unpopular and was dropped after 1982. As Ford streamlined its small-block V8 engine lineup, the 351M was replaced by the 351 Windsor. Initially, the largest engine offered was the 400 V8 carried over from the previous generation; it was available only in F-350 and certain F-250 models. As similar-size engines were discontinued by General Motors and Chrysler during the late 1970s, the 400 was discontinued after 1982.

In 1983, the 460 V8 made its return as the replacement for the 400. Coinciding with the reintroduction of the big-block 460, Ford introduced another engine offering for buyers seeking higher-output engines. Largely a response to General Motors, who had offered diesel-engined pickups since 1978, Ford produced their first North American diesel F-Series in 1983, while in Argentina the F-100 carried over the same 3.3L Perkins 4.203 available since the 3rd generation F-series. Rather than develop its own engine (as GM had), the 6.9 L IDI V8 was the product of a joint venture with International Harvester. The 460 was first offered in 4x4's in 1984 as an option. Up until that point, it was never offered in 4WD models.

In 1985, the 302 Windsor gained electronic fuel injection as an option; a year later, it became standard (an industry first for full-size pickups). Trucks equipped with the 3-speed manual transmission was the second to last American vehicle to have a column-shifted manual transmission; it was discontinued after 1986. (The last being the Chevy/GMC models which was discontinued after 1987)[citation needed]

The heavy duty Ford C6 3-speed automatic transmission, marketed as the "Select-Shift" automatic, was the standard automatic transmission all years and came paired with most engine options if ordered. Various transfer cases were used, most built by New Process Gear. NP205 and NP208F cases were most common. Each feature a stick-shift 4WD engagement, with 4 speeds: 4 Low, 4 High, Neutral and 2 High. Various Borg-Warner transfer cases were also used.

Axles and differentials[edit]

This generation was the first time Ford used Independent suspension on their full size 4x4 trucks, as well as being the first time any of the Big Three (automobile manufacturers) made a 4x4 full size truck without a solid front axle. Ford & Dana Corporation called this the Twin Traction Beam or TTB and used many of Dana Spicer parts. The F-150 used a light duty Dana 44 TTB. From 1979-1984, the rear axle was typically a Ford 9-inch axle, with the Ford 8.8 axle being phased gradually until the 9" was finally phased out by 1984. The F-250 used an 8 lug version of the Dana 44 TTB called the Dana 44 TTBHD with the Dana 50 TTB being an option. The rear was a Dana 60 until mid 1985 when Ford phased out that axle for their own Sterling 10.25. Dana 60s could be either full float or semi float and came with a range of gear ratios. Up until then, early 1985 models were built with left over 1984 materials, making some parts tough to find. The F-350 used the Dana 50 TTB in front until a mid-year change in 1985, when the F-350 was fitted with the Dana 60 solid front axle. For the rear axle the F-350 trucks used a Dana 60 for the single rear wheel trucks and a Dana 70 for the dual rear wheel trucks until 1985 when Ford once again phased in their own Sterling axle.

Medium-Duty F-Series[edit]

For the first time since 1967, the medium-duty version of the F-Series (F-600 and above) were completely redesigned. Although they still shared a common cab and interior with the pickup truck line, the medium-duty line now wore separate bodywork ahead of the firewall. The larger trucks were easily distinguished from their separate fenders, much like the larger L-Series. Along with gasoline engines, diesel engines were available. Medium-duty models had the word "FORD" spelled out in between the grille from 1979 to 1983 (1980–1983 model years), and was replaced by a blue oval "Ford" logo in 1983 production (1984 model year). This design lasted until 1995 when the fenders and grille were redesigned again. This version lasted until 1998.
