The third-generation C/K series, launched in 1973, introduced a more angular, squared-off design that would define the Squarebody era. This wasn’t just a cosmetic change; it represented a fundamental rethinking of truck aesthetics and functionality. The new design prioritized practicality, durability, and a more modern appearance, setting the stage for the Squarebody’s enduring popularity.
