Launched in the fall of 1959 as a 1960 model, the first-generation C/K debuted a number of design changes for General Motors light-truck design. Replacing the Task Force range, the C/K was developed from the start as a truck chassis, no longer sharing commonality with the GM A-body platform. Though developed as a truck for the sake of durability, the C/K adopted several features from cars into its design to increase its functionality. For pickup trucks, the C/K trucks used a drop-center frame which allowed for a lower cab and lower center of gravity, and independent front suspension was paired with a coil-sprung rear axle.
