The model year 1960 marks the sixth generation of the Chevrolet Suburban. The styling of the 1960-1966 model years took cues from the late 1950s Chevrolet cars and had large oval ports above the grille. The cab featured a "wrap around" windshield. Both tailgate and "barn door" rear openings were available. From 1962 onwards, the hood styling was 'toned down' a bit, with a more modern looking hood that eliminated the large ports. In 1964, the front glass area was updated to a flatter windshield, and larger door glass.
This model series introduced a factory-equipped 4WD ("K") option for the first time. The 2WD "C" models introduced a torsion bar-based independent front suspension and trailing arm and coil spring rear. But by 1963, returned to a more conventional coil-spring approach.
Engines included both I-6 and small-block V-8s. A 305-cubic-inch 60 degree V-6 was also available on GMC models. The 305 was actually 'brought down' from GMCs medium duty truck line. It featured huge torque numbers, but was also notable for poor fuel economy. Transmissions where a 3-speed and 4-speed manual, and the automatic Powerglide.
