Ford F-250 Highboy Buyer's Guide

The Ford F-250 "Highboy" is more than just a vintage pickup; it is a legendary piece of American engineering that defined the rugged 4x4 aesthetic long before "lift kits" were a common aftermarket accessory. While Ford never officially used the name Highboy in its marketing, the nickname was coined by enthusiasts to describe the factory-stilted four-wheel-drive F-250s produced between 1967 and mid-1977.

Whether you are a seasoned collector or a first-time classic truck buyer, choosing the right Highboy requires a keen eye. Because these trucks were built during a transitional era for Ford, many lookalikes and "franken-trucks" exist on the market. This guide will help you identify a genuine Highboy, evaluate its mechanical health, and determine which model year best fits your needs.

Key Factors to Consider

When shopping for a Highboy, you are looking for specific engineering choices that separate it from the later "Lowboy" models or standard two-wheel-drive trucks.

1. The Divorced Transfer Case

The defining mechanical trait of a Highboy is the "divorced" transfer case. Unlike modern trucks where the transfer case is bolted directly to the transmission, the Highboy's transfer case is mounted separately on its own crossmember, connected to the transmission by a short "jack shaft" driveshaft. This layout required the truck to sit higher off the ground to maintain proper driveline angles.

2. Frame Width and Stance

Highboys utilize a narrow frame rail configuration (approximately 34 inches wide at the rear), which is the same width used on the F-350 of that era. To level the truck's stance, Ford installed 4-inch lift blocks under the rear leaf springs at the factory. If the rear frame is wider (approx. 37.5 inches), you are likely looking at a 1977 ½ or newer "Lowboy."

3. Body Style: Bumpside vs. Dentside

Your choice of Highboy often comes down to aesthetic preference:

• 1967–1972 (Bumpside): These feature a distinct outward-protruding "bump" line running down the side. They are prized for their classic, minimalist 1960s interiors.
• 1973–1977.5 (Dentside): These feature an inverted "dent" or concave groove along the body. These models are generally more common and offer slightly more modern cab comforts.

4. The In-Cab Fuel Tank

Authentic Highboys have the fuel tank located inside the cab, directly behind the bench seat. Because of the narrow frame, Ford could not fit a standard fuel tank between the rails. While many owners relocate the tank for safety, the presence of the original in-cab tank (or the filler neck on the cab pillar) is a primary indicator of a true Highboy.

Top Product Picks by Use Case

1. Best for Modern Use: 1977 (Early) F-250 Highboy

The final half-year of Highboy production is often the most desirable for those who actually plan to drive their trucks frequently.

• Pros: Most likely to feature an open-knuckle front axle, which provides a better turning radius; easier to find with power steering and improved disc brake options; features the heavy-duty NP205 transfer case.
• Cons: Often commands the highest market price; hardest to distinguish from the "Lowboy" without a physical inspection.

2. Best for Collectors: 1967–1972 "Bumpside" Highboy

For the purist, the early Bumpside era offers the most iconic vintage look.

• Pros: Striking vintage styling that stands out at car shows; rapidly appreciating in value; simpler electrical systems.
• Cons: Manual steering and four-wheel drum brakes make for a "workout" while driving; parts for the early Dana 24 transfer case can be harder to find.

3. Best Value/Project Truck: 1973–1975 "Dentside" Highboy

If you are looking for a truck to build or customize, the early Dentside years are the sweet spot.

• Pros: Larger production numbers mean lower entry prices; compatible with a massive variety of aftermarket parts; strong 360 V8 or 300 Inline-6 engine options.
• Cons: Most likely to have significant rust in the floorboards and cab mounts; often heavily used as farm trucks for decades.

Pros and Cons of Highboy Ownership

Pros

• Unmatched Presence: The factory 4-inch lift gives it a commanding look that modern trucks struggle to replicate.
• Mechanical Durability: These trucks were over-engineered for heavy-duty work and are notoriously difficult to break.
• Appreciation: Values for clean 1970s Ford 4x4s have climbed significantly in the last decade.
• Simplicity: You can perform almost any repair with a basic set of hand tools.

Cons

• Safety Concerns: The in-cab fuel tank and lack of modern crumple zones are significant drawbacks for daily use.
• Fuel Economy: Expect single-digit or low double-digit MPG, regardless of the engine.
• Ride Quality: The heavy-duty leaf springs and narrow frame result in a stiff, "bouncy" ride on uneven pavement.
• Steering Play: The "push-pull" steering design is prone to wandering on the highway.

Frequently Asked Questions (FAQs)

Can I fit 35-inch tires on a stock Highboy? Yes. One of the biggest selling points of the Highboy is that the factory height allows for 35-inch tires without any additional suspension modifications or trimming.

Did the Highboy ever come with a 460 V8? No. From the factory, Highboys were only available with the 240 or 300 Inline-6, or the 360 FE V8. If a truck has a 460 or a 390, it has been swapped in by a previous owner.

How do I know if it is a 1977 Highboy or Lowboy? Check the transfer case. If the transfer case is "divorced" (separated from the transmission by a small driveshaft), it is a Highboy. If it is bolted directly to the transmission (married), it is a Lowboy.

Are parts expensive? Mechanical parts (engine, brakes, bearings) are very affordable and available at most local auto parts stores. However, original trim pieces, grilles, and rust-free body panels can be quite expensive.

Final Verdict

The Ford F-250 Highboy is a quintessential American classic that offers a "pure" trucking experience. If you want a vehicle that feels invincible and holds its value, the Highboy is an excellent choice.

For the average buyer, we recommend searching for a 1973–1977 model, as they offer slightly better parts availability and cab comfort. However, regardless of the year, your priority must be finding a solid, rust-free frame and cab. Mechanical issues can be fixed easily in a weekend, but a rusted-out Highboy frame is a costly and difficult project. Always verify the "divorced" transfer case and narrow frame width to ensure you are buying a genuine piece of Ford history.
