For half a century, the GM Squarebody, encompassing the Chevrolet and GMC C/K series trucks and SUVs produced from 1973 to 1987 (1991 for SUVs), has captured the hearts of truck enthusiasts, collectors, and everyday drivers alike. Its simple yet robust design, coupled with its versatility and reliability, cemented its place as a cornerstone of American automotive culture. The 50yr anniversary GM Squarebody celebration is more than just nostalgia; it’s a recognition of the truck’s historical significance and continued relevance.

The Origins and Design of the Squarebody

The third-generation C/K trucks, internally known as the “Rounded Line” but affectionately dubbed “Squarebody” by the public, represented a significant departure from their predecessors. GM aimed for a more modern and utilitarian design. The name “Squarebody” comes from the truck’s boxy, angular styling, characterized by its flat body panels, squared-off wheel arches, and prominent front grille. This design wasn’t just aesthetic; it was functional, providing increased interior space and improved aerodynamics compared to earlier models.

Key design features that defined the 50yr anniversary GM Squarebody trucks include:

Boxy Silhouette: The unmistakable square shape that gave the truck its nickname.
Wrap-Around Windshield: A larger windshield that provided improved visibility.
Two-Tiered Grille: A distinctive grille design that varied slightly between Chevrolet and GMC models.
Available Crew Cab: Offering seating for up to six passengers, enhancing the truck’s practicality.

The Evolution of the Squarebody: Model Years and Key Changes

The GM Squarebody underwent several updates and revisions throughout its production run. Understanding these changes is crucial for appreciating the evolution of the 50yr anniversary GM Squarebody:

1973-1979: The Early Years

The initial Squarebody models featured a relatively simple design and a range of engine options, including inline-sixes and small-block V8s. These years saw the introduction of the Cheyenne and Scottsdale trim levels for Chevrolet, and the Sierra and Sierra Grande for GMC. The 1975 models saw the introduction of catalytic converters, marking a step towards emissions compliance. In 1977, GM introduced the dual headlight design on some models, further differentiating the Squarebody’s appearance.

1980-1987: Mid-Cycle Updates

The 1980s brought significant changes to the Squarebody lineup. A new, more aerodynamic front end was introduced, featuring a flatter grille and rectangular headlights. This facelift improved fuel efficiency and gave the trucks a more modern look. GM also introduced the 6.2L Detroit Diesel engine, offering improved fuel economy for heavy-duty applications. The 1981 model year saw the introduction of the Computer Command Control system, further refining emissions control. These changes are important to note when considering the 50yr anniversary GM Squarebody.

1988-1991 (SUVs): The Extended Run

While the pickup trucks were replaced by the GMT400 platform in 1988, the Squarebody-based SUVs (Chevrolet Blazer, GMC Jimmy, and Suburban) continued production until 1991.
