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 a nickname).
 
The second-generation C/K was produced from the 1967 to the 1972 model years. Alongside multiple updates resulting from changes in federal regulations, the Action-Line trucks underwent a mid-cycle revision for the 1971 model year.  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.
 
The Action-Line C/K chassis served as the basis for the sixth-generation Chevrolet Suburban/GMC Carryall.  In line with its Jeep Wagoneer and International Travelall competitors, the Suburban received a rear passenger door (only on the passenger side); for the first time, the model line was also offered in a 3⁄4-ton payload series.  In line with the pickup trucks, the Suburban/Carryall was offered in both rear-wheel drive and four-wheel drive.
 
After the 1970 model year, GM discontinued the panel van configuration of the Suburban, functionally replaced by the 1971 introduction of the G-Series Chevrolet Van/GMC Vandura. However, the side-hinged rear panel doors would remain a notable design feature of the Suburban for three further generations (lasting through 2005).
 
For 1969, GM introduced the Chevrolet K5 Blazer and GMC Jimmy utility vehicles.  Derived from the 1⁄2-ton K-series, the Blazer/Jimmy was an open-top vehicle competing against the Ford Bronco and International Scout.  The Blazer/Jimmy was offered in three configurations; alongside the standard open-top configuration, the model line was offered with either a convertible soft-top or a lift-off hardtop for weather protection.
 
While larger than its competitors, the use of the pickup truck chassis offered the advantage of lowered production costs and shared components, as the 1974 Dodge Ramcharger and the 1978 Ford Bronco adopted a similar configuration.
