If you are a Ford truck lover, you’ve probably heard the term “HighBoy” used to describe some F250s. But what exactly is a Ford Highboy?

A Ford Highboy (also Hi-Boy) is the designation used to refer to a four-wheel F-250 produced between ‘67 - ‘77. Because Ford used a divorced transfer case, the truck sat up higher to accommodate the component, hence the name “Highboy.” These trucks are very popular with classic truck collectors.

While Ford never officially sanctioned the term “Highboy” to refer to their trucks, they didn’t mind the distinction it offered. While the competition used an integrated transfer case on its 4x4 heavy-duty trucks, Ford chose a different route. Instead of marrying the transfer case to the transmission, Ford incorporated a separate transfer case (Dana 24, NP203, NP205) on their existing 2WD transmission. The left-sided t-case required a longer driveshaft and needed to be installed farther back under the chassis, which resulted in the truck’s front end rising. To help level out the truck, Ford raised the back end, but their truck sat higher than the competition’s pickups. So what makes these classic trucks so desirable by collectors? In this article, we review the features and specs of this beautiful truck and why it is on everyone’s list as one of the best trucks Ford has ever produced.

What Is A Ford HighBoy?

A Ford “Hi-Boy” is a designation that Ford owners placed on the four-wheel drive F250s that were manufactured from 1967 - 1977.5. While Ford never used the term in its official sales brochures, the company didn’t discourage it.

The truck sat about four inches higher than the competition due to the divorced transfer case. The two-speed transfer case required a longer front driveshaft and had to be set farther back, which meant Ford had to raise the F250’s front. To compensate and prevent the truck’s nose from pointing to the sky, Ford installed a four-inch lift on the rear end. The lift meant that 4x4s had a high center than their Ford F 250 2WD, which forced owners to make decisions about whether they wanted to drive a truck with a higher center of gravity. The higher height kept Ford from offering the 4x4 F250 as a part of the Camper Special Package due to the increased chance of the camper rolling over. (It did offer a Camper Special on 4x2 models).

The Features of the Ford High-Boy

When Ford introduced the fifth generation of their F-Series, they kept many design cues implemented during the 1965 redesign. The F-Series had rebuilt the fourth generation with a new platform incorporating the Twin I-Beam suspension. For the new model, engine choices were expanded, and new, more luxurious interiors were offered.

The sales brochure for the new fifth generation promoted the fact that Ford trucks “worked like trucks, but ride like cars.” A rising middle class of buyers demanded more amenities and better ride quality in all their vehicles. The truck size was increased to provide more interior cabin space and visibility, and a new trim level (Ranger) was added, all designed to make new buyers more comfortable.


For the 1967 model, the straight lines of the truck were lengthened, and the body and hood were reinforced with double-walled construction to provide better stability. The truck was offered in Styleside and Flareside versions, with a 131-inch wheelbase and an 8-foot cargo bed.

The front end presented a solid appearance with a chrome latticed insert extending across the

front fascia as the iconic FORD lettering stood out from the front lip of the hood. Small chrome recessed headlights bookend the front, resting on top of small rectangular orange parking lights. A solid chrome bumper undergirded the front end, matching the chrome door handles, and upgraded rims.


Initially, Ford used a standard 240 cu. in. inline six as the standard engine, with a 300 cu. in. inline six and 352 cu. in. V8 as engine options.

Engine Horsepower
240 cu. In. Inline Six 150 HP @ 4000 rpm
300 cu. In. Inline Six 183 HP @ 3600 rpm
352 cu. In. V8 208 HP @ 4400 rpm

In 1968, Ford dropped the 352 for the powerful 360 and 390 V8s. Truck owners needed more power and torque for towing applications, and Ford was desperate to keep its customers happy. (Ford tinkered with its engine choices for 4x4 units throughout the fifth generation production run. For example, 1970 offers only 300 cu. In. Inline six or the 360 V8).

360 cu. In . V8 215 HP @ 4400 rpm
390 cu. In. V8 255 HP @ 4400 rpm

The sixth generation in 1973 offered three engine offerings (240 or 300 inline six or 360 V8) until 1976, when the FE engines were dropped for the stronger, updated 351M V8 and 385 V8s (for the 1977 model).

351M cu. In. V8 156 Horsepower @ 4000 rpm
400 cu. In. V8 169 Horsepower @ 4000 rpm


The 1967 F250 4x4 offered two transmissions, the 3-speed manual and a 4-speed New Process 435. (Automatic transmissions were developed with the 1973 model of the F250 4x4). The three-speed top-loader was built for F250s from 1967 - 71. Owners appreciated that both the F100 and F250 4x4s engaged the 4WD through a single shift lever without the need for clutching or stopping.

Suspension and Braking

Ford used the Twin-I beam suspension with large, heavy-duty leaf springs with reinforced shocks on both the rear and front. A dual master cylinder sent brake fluid to both the front and rear brakes independently so that if one system failed, the other could take over. Ford went to standard disc brakes in 1976.

Cab Configurations And Interior

In 1967, Ford highlighted their interior with a new Ranger option that offered wider seats, more padding, and a swept-away dashboard. The Ranger trim offered vinyl and cloth seating, wall-to-wall carpeting, and chrome accents on the window handles and dashboard. The instrumentation was easy to read, with enlarged gauges and a comfortable three-spoke steering wheel. Optional equipment like power brakes and power steering was available. Ford would eventually add XLT to the Ranger trim (Ranger XLT) and move the Ranger name to its mid-level package.

Owners who wanted less luxury could opt for a Custom or Standard cab interior. Ford tried to encourage owners with different styles, from Sport Custom line to Free-Styling (which offered color-coordinated orange, brown and yellow decals on the doors and bed exterior.

Ford offered Regular Cab and CrewCab versions until 1974, when it introduced a middle SuperCab configuration. The added space in the cab happened because Ford moved their gas tank from its rear wall to integrate it into the frame.

Ford offered multiple colors for the exterior, averaging between 12 - 15 colors per year. Two-tone options were offered so owners could customize their trucks with a contrasting white color (White Wimbledon).

For the 1978 model year, Ford abandoned the divorced transfer case preferring to go in an integrated system and offer costumer’s the choice of a part-time or full-time four-wheel drive. The part-time four-wheel drive used the NP205, which was gear driven, while full-time units had a chain-driven NP203. The result was that Ford trucks lowered in height, which prompted owners to nickname them “LowBoy.”
