when did ford start the twin i beam
Ford F-Series In 1965, the F-Series was given a significant mid-cycle redesign. A completely new platform, including the "Twin I-Beam" front suspension, was introduced that would be used until 1996 on the F-150 and until 2016 on the F-250/350 4x2. Additionally that year, the Ranger name made its first appearance on a Ford pickup; previously a base model of the Edsel, it was now used to denote a high-level styling package for F-Series pickups.[4]
