When did Ford stop using twin I beam?

Ford’s Use of Twin I-Beam Suspension
Ford stopped using the Twin I-Beam suspension in various F-Series trucks until 2002. The heavy-duty coil spring can compress and expand on its own, without disturbing the opposite wheel. The Twin I-Beam suspension was utilized on F250 and F350 models, although it’s no longer prominently featured in advertisements and is instead buried deep in the spec sheets for two-wheel drive highway machines.
In 1965, Ford introduced the Twin I-Beam front suspension with the goal of improving ride quality, reducing tire wear, and reducing front end maintenance. This revolutionary suspension system featured two rugged I-beam axles to share the abuse of rough terrain, and it was initially used in Ford’s half-ton pickup trucks for the first couple of decades. However, the heavy-duty three-quarter and full-ton pickups (F250 and F350) continued to use the old mono-beam suspension. Eventually, Ford realized the need to smooth out the ride of the F250 and developed a version for four-wheel drive trucks (TTB – Twin Traction Beam).
The Twin I-Beam design by Ford broke the single axle into two single beams for each wheel, attached at their own independent spring and pivot point, allowing one wheel to roll over uneven ground with less effect on the other wheel and passengers. Radius rods attached the beams to the vehicle’s side rails, providing more control over the front end. However, Twin I-Beams were eventually replaced with an A-arm suspension setup by Ford due to difficulties in adjusting the ride height and handling concerns.
In summary, Ford stopped using the Twin I-Beam suspension in various F-Series trucks until 2002, and it was replaced with other suspension systems for improved ride quality and handling.
