Classic Ford F-Series Truck with 2WD to 4WD Conversion Kit

Understanding 2WD to 4WD Conversion

Converting a 2WD to a 4WD enhances off-road capabilities, traction, and can also increase the truck’s value in the eye of certain buyers. This conversion is a popular choice for vintage Ford truck owners who want to upgrade their vehicle’s performance while preserving its classic appeal. We’ve got some before and after photos that really show the difference!

The Ford F-Series: Classic and Versatile

The Ford F-Series trucks, particularly from 1965 to 1979, are iconic for their durability and design. These models, being more abundant in 2WD, are perfect candidates for 4WD conversions, offering a new lease of life and versatility.

Why Are There More 2wd Ford Trucks Available FromThe Years 1965 to 1979?

The predominance of 2WD Ford trucks over 4WD models from 1965 to 1979 can be attributed to several factors:

Market Demand and Usage: 

During this period, the Ford F-Series trucks, such as the F-100, F-150, F-250, and F-350, were primarily workhorses. The 4WD versions of these trucks were not as common, with many ending up as farm trucks and often heavily used. On the other hand, 2WD versions were produced in higher volume, as they were more in demand for general use and transportation needs. For example, in 1974, Ford manufactured significantly more 2WD half-ton pickups compared to 4WD half-ton pickups.

Technological Development: 

The technology and manufacturing processes in the 1960s and 1970s were more conducive to producing 2WD vehicles. The introduction of features like Ford’s Twin I-Beam independent front suspension in 1965 for 2WD trucks offered a more car-like ride while maintaining work-truck strength, which was a significant selling point at the time.

Cost and Complexity: 

4WD systems are generally more complex and expensive to produce than 2WD systems. This complexity and higher cost likely influenced Ford’s production decisions, favoring the simpler and more cost-effective 2WD models for the mass market.

Condition and Survival Rate: 

Many of the 4WD versions from this era ended up in roles that led to harder use and more wear, such as on farms. This means that fewer have survived in good condition compared to the 2WD versions, which were more likely used in less demanding conditions and thus have a higher survival rate today.

Is the Conversion Worth It?

Considering the increase in functionality and potential rise in resale value, these conversions are often seen as a worthy investment. They not only enhance the truck’s performance but also contribute to its uniqueness and appeal.

Here are ten reasons for considering a 4 Wheel Drive Conversion for your Old Ford Truck:

  1. Enhanced Off-Road Capability: 4WD allows for better traction and handling on off-road terrains, such as mud, sand, and rocky paths.
  2. Improved Traction in Adverse Conditions: In snowy, icy, or slippery conditions, a 4WD system provides better grip and control.
  3. Increased Resale Value: Converting to 4WD can increase the market value of your truck, as 4WD vehicles are often more sought after.
  4. Versatility in Use: A 4WD truck can handle a broader range of activities, from daily driving to adventurous off-roading.
  5. Better Towing Performance: 4WD trucks generally offer improved towing capabilities, especially on uneven terrains or in challenging conditions.
  6. Historical Preservation with Modern Utility: The conversion allows owners to retain the classic aesthetic of their old Ford truck while upgrading its functionality.
  7. Personal Satisfaction: Many truck owners enjoy the process of upgrading and customizing their vehicles as a hobby. And almost everyone wants their truck to be a 4 Wheel Drive.
  8. Improved Use in Difficult Driving Situations: 4WD can offer better control and stability, which is crucial for safety in challenging driving scenarios.
  9. Rarity and Uniqueness: A converted 4WD vintage Ford truck can stand out due to its unique combination of classic design and modern functionality.
  10. Adventure and Exploration Opportunities: Owning a 4WD truck opens up possibilities for exploring more rugged and remote locations that would be inaccessible with a 2WD vehicle.
