<P> For the 1953 model year, an all - new version of the F - Series made its debut . Increased dimensions, improved engines, and an updated chassis were features of the second generation . </P> <P> Additionally, a change to the F - Series naming scheme would remain in place to the present day . The half - ton F - 1 became the F - 100 (partially influenced by the North American F - 100 Super Sabre); the F - 2 and F - 3 were combined into the F - 250 while the F - 4 became the F - 350 . Conventional F - Series trucks were F - 500 to F - 900; COE chassis were C - Series trucks . </P> <P> While large body parts are the same from 53 - 56 F - 100 & F250's (namely the hood, fenders, and all bed components) in 1956 Ford did a redesign of the cab, changing the shape of the windshield, doors and door openings, and also offering a rear panoramic "Big Back Window" option . This makes the 1956 F series trucks into a one year only truck . </P> <P> Other changes in 1956 were made to the dashboard of the F - series trucks, further making them more unique </P>
