The Ford F-150 nameplate first appeared for the 1975 model year inside the sixth-generation F-Series that collectors call the "Dentside," named for the long horizontal crease pressed into its body sides. Ford slotted the 1975 F-150 between the F-100 and the F-250 as a heavier half-ton, and set its gross vehicle weight rating just above 6,000 pounds. That figure kept the 1975 F-150 in the heavy-duty emissions class, so it avoided the catalytic converter and unleaded-fuel requirement that hit the lighter 1975 F-100. The standard engine was the 300-cubic-inch (4.9L) inline-six, with the 302 (5.0L) Windsor V8 as the entry V8 across the run. The larger V8 options changed during the period: the 360 and 390 FE V8s through 1976, then the 351M and 400 V8s from 1977, with the 460 big-block offered across the period in two-wheel-drive trucks. Four-wheel-drive 1975-1979 F-150s used a solid Dana 44 front axle, the setup that preceded the Twin-Traction Beam introduced for 1980. The F-Series became the best-selling truck line in America for 1977, a position it held through this generation's final year of 1979.
Other Ford F-150 generations
Ford F-150 1975-1979 at a glance
- Generation: Sixth-generation Ford F-Series, the 1973-1979 "Dentside." The F-150 nameplate joined the line for the 1975 model year.
- Body styles: Two-door regular cab and the extended SuperCab (the SuperCab arrived for the 1974 F-Series, before the F-150 name); Styleside and Flareside beds.
- Standard engine: 300-cubic-inch (4.9L) inline-six.
- V8 options: 360 and 390 FE V8s through 1976; 351M and 400 V8s from 1977; 302 V8; 460 big-block in two-wheel-drive trucks across the run.
- Transmissions: three-speed and four-speed manuals, plus the C6 three-speed automatic.
- Four-wheel drive: solid Dana 44 front axle (the Twin-Traction Beam independent front arrived for 1980, after this generation).
- Why the F-150 exists: Ford set the 1975 F-150 GVWR just above 6,000 lb to place it in the heavy-duty emissions class, exempting it from the 1975 catalytic converter and unleaded-fuel rule that applied to the F-100.
- Generation end: 1979 was the last year of the Dentside body; the "Bullnose" seventh generation followed for 1980.
Year-by-year changes
| Model year | Standard engine | V8 options | Key changes |
|---|---|---|---|
| 1975 Ford F-150 | 300 cu in (4.9L) inline-six | 302, 360, 390, 460 | F-150 nameplate introduced as a heavier half-ton between the F-100 and F-250; GVWR set just above 6,000 lb so the 1975 F-150 avoided the catalytic converter and could run leaded fuel. |
| 1976 Ford F-150 | 300 cu in (4.9L) inline-six | 302, 360, 390, 460 | Final year for the 360 and 390 FE V8s in the light-duty F-150. |
| 1977 Ford F-150 | 300 cu in (4.9L) inline-six | 302, 351M, 400, 460 | The 360 and 390 FE V8s were dropped; the 351M and 400 V8s of the 335-engine family replaced them in the 1977 Ford F-150. The Ford F-Series also became the best-selling truck line in the United States for 1977. |
| 1978 Ford F-150 | 300 cu in (4.9L) inline-six | 302, 351M, 400, 460 | Rectangular headlamps appeared on higher trims (Ranger, Ranger XLT, Ranger Lariat) while the Custom kept round lamps; the Ranger Lariat trim was added. Four-wheel drive became available on the SuperCab. |
| 1979 Ford F-150 | 300 cu in (4.9L) inline-six | 302, 351M, 400, 460 | Final year of the Dentside sixth generation; rectangular headlamps were used across the F-150 range. The 1980 model year brought the redesigned "Bullnose" body and Twin-Traction Beam front suspension. |
Why Ford created the F-150 for 1975
The Ford F-150 was a regulatory response as much as a product. For the 1975 model year, federal rules required light-duty vehicles rated at 6,000 pounds gross vehicle weight or less to use a catalytic converter and unleaded fuel. Ford set the 1975 F-150 at a GVWR just above that 6,000-pound line, which placed it in the heavy-duty class and exempted it from the converter requirement. The result was a half-ton Ford F-150 that could still run leaded fuel and carry a slightly higher load rating than the F-100 it sat above. The 1975 F-100 of the same generation, by contrast, did receive a catalytic converter. The F-150 sat between the F-100 and the three-quarter-ton F-250 in the lineup.
Engines of the 1975-1979 Ford F-150
The base engine across the 1975-1979 Ford F-150 was the 300-cubic-inch (4.9L) inline-six, a long-stroke truck six rated in net horsepower because all 1972-and-later figures were reported as net rather than the older gross numbers. The 302-cubic-inch (5.0L) Windsor V8 was the entry V8. The larger V8 menu changed mid-generation: through 1976 the 1975-1976 Ford F-150 offered the 360 and 390 FE-family V8s, and for 1977 Ford replaced those with the 351M and 400 V8s of the 335-engine family. The 460-cubic-inch (7.5L) big-block of the 385-engine family was the top engine and was offered in two-wheel-drive Ford F-150 trucks through the period. Net output for these emissions-era engines was modest by later standards; the 300 inline-six produced roughly 114 to 120 net horsepower depending on year and configuration.
Drivetrain, axles, and four-wheel drive
The 1975-1979 Ford F-150 used a body-on-frame layout with a leaf-sprung live rear axle. Transmissions included three-speed and four-speed manuals plus the Ford C6 three-speed automatic, which was paired with the higher-torque engines. Four-wheel-drive 1975-1979 Ford F-150 trucks used a solid Dana 44 front axle, the beam-axle setup that preceded the Twin-Traction Beam independent front suspension Ford introduced for the 1980 F-150. Four-wheel drive on the extended SuperCab body became available for 1978 on the Ford F-150. The 460 big-block was not offered with four-wheel drive in this generation and was a two-wheel-drive option.
Trims and body styles
The 1975-1979 Ford F-150 was sold in a range of trim levels that included the base Custom, the Ranger, the Ranger XLT, and, added for 1978, the Ranger Lariat. The Ranger and higher trims added carpeting, color-keyed interior fabrics, and wood-tone interior trim. The Ford F-150 came as a two-door regular cab and as the extended SuperCab, which the F-Series had introduced for 1974. Bed choices were the smooth-sided Styleside and the running-board-style Flareside. For 1978 the higher Ford F-150 trims switched to rectangular headlamps while the Custom retained round lamps, and for 1979 the rectangular lamps were used across the range.
