1967 Kenworth W-900a

In 1967, the W900 underwent its first major change and was renamed the W900A. To accommodate larger diesel engines, the hood was widened several inches to further increase radiator size. For 1972, the doors of the W900 were changed, with the model adapting larger windows, narrower vent windows; for ease of use, the door handles were re-positioned to the bottom of the doors and changed from a lever-style to a pull-style configuration. In 1973, the Kenworth badging was changed, with a redesigned grille emblem and hood badging. In 1974, a 60-inch flattop double sleeper was introduced as a factory option.
