The second generation of the C/K series is a range of trucks that was manufactured by General Motors. Marketed by both the Chevrolet and GMC divisions from the 1967 to 1972 model years, this generation was given the "Action Line" moniker by General Motors (the first-generation C/K did not receive such a name). As with its predecessor, the second generation C/K included full-size pickup trucks, chassis cab trucks, and medium-duty commercial trucks. Produced by multiple sites across the United States and Canada, the model line was also produced in South America.
