1961–1966 Ford Unibody Pickups: Steel, Torque, and a Little Bit of Rebellion

The 1961–1966 Ford F-Series trucks weren’t just transportation—they were rolling mechanical blueprints.

1961–1966 Ford Pickups: Steel, Torque, and a Little Bit of Rebellion

The 1961–1966 Ford F-Series trucks weren’t just transportation—they were rolling mechanical blueprints. No plastic covers. No fake engine noise. Just iron, oil, and whatever grit you brought to the job.

The Unibody Experiment (1961–1963)

Ford welded the cab and bed into a single structural unit on F-100 2WD short and long  beds. The idea? Increase torsional rigidity and reduce assembly complexity. The cab back panel and front bed wall became one structural stamping. Crossmembers tied into the frame rails differently than the standard Styleside.

Problem: when you loaded 1,500+ lbs of gravel, stress transferred into the cab structure. Door gaps changed. That wasn’t a rumor—that was geometry. The design eliminated the normal flex isolation between cab mounts and bed mounts.

By 1964, Ford went back to separate bed construction for durability under commercial loads.

  • Bore x Stroke: 4.00" x 3.50"
  • ~208–220 hp
  • ~315 lb-ft torque
    Solid lifter variants existed in performance trims. Heavy, yes. Stronger than your buddy’s bragging rights.

Transmissions & Drivetrain

  • 3-speed column shift (RAN, RAT series)
  • Borg-Warner T-18 4-speed with granny low (~6.32:1 first gear)
  • Cruise-O-Matic automatic option

Rear Axles:

  • Ford 9-inch became common on all F100
  • Ratios ranged from 3.25 to 4.11 depending on load rating

Leaf spring rear suspension with solid axle. Front was straight axle through 1964.

Then 1965 Happened: Twin I-Beam

Ford introduced the Twin I-Beam independent front suspension. Two forged steel I-beams pivot from the frame crossmember. Each wheel travels independently, but camber changes dynamically through arc travel. It improved ride quality dramatically over the straight axle but created alignment geometry that modern shops still debate.

It wasn’t soft. It was smart. Long suspension travel. Forged components. Built for washboard roads.

Little-Known Mechanical Details

  • Frame rails were fully boxed in key stress areas.
  • Steering was recirculating ball design—manual or optional power assist.
  • Drum brakes all around, typically 11" units.
  • Fuel tank was in-cab behind the seat. Yes, right there. Different era.

These trucks were engineered for work cycles, not Instagram photos. Thick steel stampings. Serviceable components. Carburetors you could rebuild on a tailgate.

No computers. No nanny systems. Just torque curves, gear ratios, and the sound of a straight-six pulling hard through second gear.

If you grew up riding in the bed, you remember the smell of hot brakes and gear oil. These trucks weren’t perfect—but they were honest, and the engineering was built to outlast the guy turning the wrench.

Old Ford Drum Brake History and Tutorial

Old Ford Drum Brake History and Tutorial

Old Ford drum brake history and tutorial Pre 1967 old Ford cars and old Ford trucks used a drum brake system. In these systems, pressure applied to the brake pedal is transmitted to the master cylinder, which in turn disperses the energy ultimately to the brakes in each wheel. The master cylinder uses the brake fluid to move the wheel cylinders, which in turn moves the brake shoes in the drum. There is a front and back brake shoe, the rear one for stopping a vehicle in drive and the forward one for stopping a vehicle in reverse. When either shoe is pressed against the anchor pin, the brakes are engaged, and the vehicle comes to a stop. The brake pads form the shoes to the anchor pin so there is no slipping. The padding on the rear brake shoe is typically longer and sometimes made of a different material to allow the shoes to wear at a similar rate, since the rear shoe sees much more use. The brake shoes are secured in the drum with both hardware and return springs, which must meet ideal sizing and tension specifications for your make and model for top brake performance. These parts should be replaced any time you work on the brakes in order to counteract wear and tear that can lead to longer stopping times. Stock brake line hoses will have a rubber lining, while aftermarket hoses are available in a stainless braided wrap to preserve the hose. Whichever type you get, make sure the hoses are the correct thread size and length for your year and model and meet DOT safety standards. The rear wheel drum brakes will also contain the parking brake mechanism and will have a cable to the parking brake. Brake pipe must be double flared and use flared nuts. It can be purchased with the flaring already completed or you can cut your own and flare it yourself, but it should meet or exceed DOT safety standards. Hydraulic brakes will fail if there is a weak point in the system, so make sure all your hose and fittings are SAE rated and correctly installed. If you are unsure after installation, test the brakes at low speed in a safe area, such as your driveway or an empty parking lot before taking the vehicle on the road. Starting in 1967 all old fords have a dual master cylinder. This part separates the wheel hydraulics of the front and rear of the car, so a failure in one will not cause a failure in the other. In vehicles without this feature, a leak anywhere in the brake line will cause the entire brake system to fail. With a dual master cylinder, a leak in the front brake system will not affect the rear and vice versa. This is standard in vehicles made after '67, but it's a good safety upgrade for older classic Fords as well. Many classic Ford owners choose to upgrade their front brake system to disc brakes, or the complete system. Drum brakes can overheat and fail in high braking conditions, such as rapid stops at high speeds or driving downhill on mountainous roads. Disc brakes are open and exposed to the outside air, which prevents overheating and brake failure. While this upgrade is not strictly necessary, it's a good idea if you frequently drive in hilly or mountainous areas. Original Ford brake shoes used asbestos in the brake pads. If you are working on a vehicle with its original brake shoes or if you are uncertain if they are original, wear a respirator rated for asbestos while working and wet the brake pads before opening the drum to prevent the asbestos from becoming air born. When cleaning dust from drum brakes, use a dense filtration system to trap the asbestos and dispose of it properly. You can resurface a drum with minor surface issues, but make sure it stays within factory limits for your year and model. Worn or thin drums can break apart or crack and cause brake failure. If you see excessive wear and tear, replace the drum. If you are replacing a leaking wheel cylinder, it's a good idea to do them all at once, including the master cylinder. If you have had problems with one, you will soon have problems with the rest. In addition, you won't need to remember which cylinder was replaced when for future maintenance if they were all replaced at once. You can use a vacuum bleeder to remove old brake fluid and contaminants. Once you remove the old fluid you can use denatured alcohol followed by air to purge the lines. Vacuum each cylinder, including the master cylinder, and replace the old fluid with new, DOT 3 or 4 fluids. When changing fluid, change the rubber hoses and seals. If you have a combination disc and drum system, only use DOT 4 fluid. To ensure a complete cleaning, vacuum some of the new fluid through as well do catch any missed contaminants. When working on or near the brake line, make sure no petroleum-based liquid, such as gasoline, oil, or mineral oil, encounters the hosing. These oils can break down the rubber and cause hoses to start leaking. Make sure to wash your hands thoroughly before and during working on the brakes system to prevent this, especially if you have been working on other parts of the vehicle. When working on your brakes, make sure to follow safety precautions, use safety rated parts, and check over your work carefully. Drum brakes are a very important part of the machinery, and due to the hydraulic system, can easily lose stopping power or fail if something is wrong, especially without a dual master cylinder. Whether you're doing regular maintenance or upgrading the whole system, working carefully will ensure a successful job for your vehicle.
FORD F100

FORD F100 HISTORY

FORD F100 HISTORY In 1953, Ford launched a fresh era of F Series pickups. The 1953 pickups were officially called F-100 and featured sleeker designs with an all-new cab and front end design. This generation of F Series pickups had larger measurements that included 55% larger windshield glass due to its curved design. With the wider cab you can seat 3 full size adults. 1953 Ford also improved chassis now available in 110” and 118” wheelbase (1948-52 is 114”). The gas tank was moved from behind the seat and now mounted on the outside of the frame below the driver’s side of the cab. The upgrades were designed to foster toughness and driving performance. The F Series pickups also took on new names. The F-2 became the F-250. The F-3 was renamed the F-350. Options included a dome light, cigarette lighter, ashtray, sun visors, radio, recirculating air heater and hot water heater. The new name was retained by the F-100 until Ford discontinued production of the F-100 after the 1983 model-year. In 1954 the all-new 239 CID "Y" block engine became available. The 1956 F-100 was celebrated for its perpendicular windshield pillars and its wraparound windshield. Available on the Custom Cab model is a wraparound rear window. The “Y” block 272 was now available as was the 223 6 Cylinder. The gas tank was moved back into the cab behind the seat. Assembly of the F-100 in this time took place mostly in Dearborn, MI. Ford also made approximately 101,000 to 184,000 models of the F100 in Sao Paulo, Brazil. SECOND GENERATION The second generation of the Ford F-100 ran from 1957 through 1960. The important styling change for this generation was a lower hood sitting flush on top of the front fenders. Ford launched its tradition of providing two different pick up box styles in this generation. Separate rear fenders were featured on the traditional Stepside design. The new released Styleside layout featured smooth sides as well as a far more streamlined look. New for 1958 was the use of four headlights, Ford continued this until 1960. In 1959, Ford began making the F-100 with a unique four wheel drive. Ahead of this new development, outside makers such as American and Marmon-Herrington and Coleman occasionally converted normal Ford trucks to four wheel drive. The next generation of the vehicles also marked an increase in sales of the optional eight-foot bed for the F-100, the typical length of the bed was six and a half feet. The eight-foot bed eventually eclipsed its smaller counterpart in popularity among F-100 motorists. Assembly continued to take place in the Ford plant in Dearborn, MI. THE 3RD GENERATION The new pickups were lower to the ground and wider than earlier versions. 1961 F-100 offered the optional uni-body, which combined the cab and box into one body. Ford discontinued the unibody design at the end of the 1963 production after it fared dismally in the marketplace. 1961 and 1962 Ford still used one piece hood side emblems. In 1963 new body side trim was now available on the styleside trucks with a red painted stripe in the center of the trim. The all new hood side emblem now included a plastic insert with the size of the truck “100”, “250”, “350”. In 1965 designers lowered the cab floor enhancing interior room. 1965 Ford also launched the first of its all new front suspension the "Twin I-Beam". 1965 Also offers a 352 "FE" motor instead of the “Y” block 292. The 6 Cylinder engine is also upgraded from the 223 to the new 240. Ford offered the Ranger option in 1965. The designation referred to your field of options that included an interior optional bucket seats with console and carpeting instead of a rubber floor mat. Ford changed some of its own assembly in this time to a plant in Cuautitlan, Mexico. FOURTH GENERATION Ford engineers continued their emphasis on pickups in 1967 that offered a degree of comfort which was similar to a car. 1967 Has new unique hood side emblems. 1967 offered new exterior trim, the body side trim is also new 1-1/4” wide with thin black line top and bottom as well as, available rocker trim. With the new designed cab now includes a new cargo light for the bed at the back of the cab above the rear window. 1968 Changed the hood side emblem to include a reflector. Lower bed side reflectors are standard. The exterior trim is now wider at 1-1/2” wide with the black thin line top and bottom. The Ranger option now includes a grille emblem. New for 1968 is interior door lock knobs. The exterior trim is changed again for 1970. The grille is all new with a plastic inert for either side of the grille. The front of the hood now has a trim going from side to side. The bed side reflector is moved from the lower bed side to the end of the body side trim and now has a light in it. The new Ranger and Ranger XLT trim is now 3-5/8” wide. The new wide trim is available with either black for the Ranger option or woodgrain for the Ranger XLT. 1971 The steering wheel is changed to a two spoke wheel with optional black or woodgrain horn pad. FIFTH GENERATION OF THE F100 AND INTRODUCTION OF THE F-150 The F-100 underwent major refinements for the fifth generation of the F Series, which ran from 1973 through 1979. Ford released the F-150, a fresh version, in 1973. The F-150 was essentially an F-100 with a spring package in the front and back that enabled the vehicle to carry a heavier load. Ford stopped production of the 4x4 F-100 in 1978. New grille with new plastic inserts for 1973 with the plastic insert now going around the headlight. The XLT option now included a grille emblem. The side trim was now available with a rubber insert down the center of the trim. The side reflectors now had light sockets with the front ones mounted in the front fenders and the rear still at the back of the bed trim. With the all new dash design trucks optioned with factory air conditioning now had vents in the dash for the air to go through and no longer was the air conditioning unit hanging from under the dash. 1974 Ford offered the new “Super Cab” with had a back bench seat and quarter windows behind the door. The new quarter windows were available fixed and with a pop out version. 1977 Offered a new exterior rim called “Race Trak” trim. The trim was a thin molding that started on the front fender at the grille and went down the side of the truck and curved up the bed side to meet the body side trim. Mid year 1978 Ford switch to square headlights which became standard for the F series trucks. Ford stopped producing the venerable F-100 entirely following the 1983 model year.
