How much does a 1979 Ford F100 weigh?

Approximately 3,900 to 4,800 pounds in curb weight, depending on configuration. Two-wheel-drive models typically sit near the 4,000-pound mark, while four-wheel-drive versions are heavier by several hundred pounds. Bed length and engine choice are the main drivers of the variation.


What determines the curb weight


The curb weight of a 1979 Ford F-100 varies with drivetrain, cab/bed configuration, and engine size. Understanding these factors helps explain why a single model year can span a broad weight range.


Before reviewing the factors, note that exact figures depend on the specific build sheet and options installed on a given truck.



  • Drivetrain: 2WD (two-wheel drive) versus 4x4 (four-wheel drive) adds weight due to the transfer case, front axle, and additional drivetrain hardware.

  • Bed length: Long-bed versus short-bed models differ in sheet metal and chassis components, affecting weight.

  • Cab configuration: Extra or extended cabs and certain trim levels contribute modest weight differences.

  • Engine size: Larger V8 options increase the curb weight through heavier blocks and fuel systems.


In practice, 2WD regular-cab, long-bed trucks are typically around 4,000 to 4,200 pounds, while 4x4 variants push toward the upper end of the spectrum, roughly 4,500 to 4,800 pounds depending on the exact setup.


Typical curb weight by configuration


The following figures represent representative ranges for common setups in the 1979 Ford F-100 line. Exact weight will vary by build sheet and market options.



  • 2WD Regular Cab, Long Bed: approximately 4,000–4,200 lb (1,815–1,905 kg)

  • 2WD Regular Cab, Short Bed: approximately 3,900–4,000 lb (1,769–1,815 kg)

  • 4x4 Regular Cab, Long Bed: approximately 4,500–4,800 lb (2,041–2,177 kg)

  • 4x4 Regular Cab, Short Bed: approximately 4,400–4,700 lb (1,996–2,131 kg)


Remember, these are typical ranges and can vary with specific engines and optional equipment. For an exact figure, check the vehicle’s data plate or the original build documentation.


Engine and drivetrain impact


Engine choice and drivetrain type are the largest single influences on curb weight among 1979 F-100 configurations. Lighter small-block V8s keep weight toward the lower end, while larger V8s and 4x4 drivetrains push it higher.



  • Small-block V8s (e.g., around 5.0 L/302): lighter end of the spectrum

  • Large-block V8s (e.g., 5.8 L/351M, 6.6 L/400): heavier

  • 4x4 drivetrain: adds a substantial weight premium due to the transfer case and front axle


For precise, vehicle-specific numbers, refer to the factory build sheet or data plate for the exact configuration you are evaluating.


Summary


The 1979 Ford F-100’s curb weight typically ranges from about 3,900 to 4,800 pounds, with 2WD trucks generally lighter and 4x4 models heavier. Bed length, cab configuration, and engine size drive the differences, and exact figures should be confirmed from the specific vehicle’s documentation or data plate.
