Ford F-100/F-150 Spotter's Guide - Four Wheeler Network
The Ford F-Series pickup trucks were introduced to the American public for the ’48 model year and continue to roll off the assembly line today after more than a dozen generations. We scoured nearly 50 years of production data, and with the help of Randy Harral, Ford aficionado and owner of Driven 4x4 Parts in Phoenix, Arizona, we came up with a ton of good information. 5th Generation (1967-1972). The late ’60s Ford pickup was the F-100 model. The 6 1?2-foot bed sat on a 115-inch wheelbase and the full 8-foot bed on a 131-inch wheelbase. Up front, Ford offered its Mono-Beam Suspension with coil springs and forged radius arms. These included the 240ci I-6, 300ci I-6, 352ci V-8 (’67 only), and 360ci V-8. Ford never offered a three-speed manual transmission in the 4WD trucks like it did in the Bronco. Instead, the fifth-generation F-100 trucks were all equipped with the sturdy New Process NP435 four-speed (6. 69:1 First gear). Rear axles were often the 28-spline Ford 9-inch, but could have been a Dana 44 or Dana 60 in the first couple of years of this generation. Gearing for the fifth-generation F-Series trucks ranged from 3. 50 to 4. 11. A limited slip or Traction-Lok was optional in the rear axle. Source: www.fourwheeler.com
