Chronology
Predecessor	Chevrolet/GMC C/K (first generation)
Successor	C/K (Rounded Line)

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).^[1][2] As with its predecessor, the second generation C/K included full-size pickup trucks, chassis cab trucks, and medium-duty commercial trucks.

The Action Line C/K marked the expansion of the General Motors utility vehicle range, as the Chevrolet Suburban (GMC Carryall) utility wagon was joined by the Chevrolet K5 Blazer (GMC Jimmy) off-road vehicle. A shorter-wheelbase version of the K-series pickup truck, the open-top Blazer/Jimmy was among the first widely produced sport-utility vehicles. This generation marked the debut of the Chevrolet Cheyenne and GMC Sierra nameplates; making their debuts as trim levels, the Cheyenne and Sierra are both used by GM to this day in current production.

Produced by multiple sites across the United States and Canada, the model line was also produced in South America.
