Square body trucks are the third generation of Chevrolet and GMC C/K pickups. They debuted in 1973 and continued until 1987. Initially called the “Round-Line” in 1973, these trucks quickly earned the nickname “square body” due to their distinctive box-like shape. Compared to earlier models, square-body trucks made significant design, functionality, and comfort strides.
The History of the Square Body Trucks
The term “square body” refers to the angular design of these trucks. Unlike their predecessors, which featured more rounded shapes, square-body trucks showcased straight lines and a bold, sturdy frame.
The design offered more interior space and a sturdier frame. Many truck enthusiasts appreciate this design for its durability and classic look, making it a beloved option for collectors.
Let’s look at how these classic trucks have grown over the years.
1973 – Introduction and Reception
When square-body trucks first hit the market, they made a strong impression. Buyers appreciated their modern look and practical features. They quickly became popular among contractors and everyday users for both work and leisure. With the way people loved this vehicle, the stage was definitely set for years of sales success.
1975 – New Features and Trim Levels
By 1975, Chevrolet had sold over 75,000 square body trucks, making it their best-selling product that year. But they didn’t end there. They wanted to cater to a wider audience and this led to the introduction of new trim levels. These gave customers more options, and buyers could customize their trucks according to their needs and preferences.
Note however, if you would like to purchase a classic square-body truck now, it’s important to verify just how authentic and reliable it is. This you can do with classic VIN decoders for 5 to 13-digit VINs.
1977 – 1979 – New Sales Records and Bigger Engines
By 1978, square body trucks set another record, with over 1.3 million units sold. This remarkable achievement showcased their growing popularity in the market. The year also introduced the 5.7L V8 diesel engine, which further enhanced the performance of these trucks and buyers really appreciated it.
This combination made the square body trucks not only practical for everyday use but also suitable for more demanding tasks, like towing and hauling.

1980 Onwards – Bigger Engines, New Designs, New Names
In the early 1980s, Square Body trucks underwent significant changes and essentially became better. They shed nearly 300 pounds through weight reduction efforts while receiving a redesigned front end and updated sheet metal. Modifications included new fenders, hood hinges, and vent windows for improved aerodynamics.
The introduction of the 4.3L Vortec V6 engine in 1985 provided an even more powerful base engine for Chevy trucks. This engine offered better fuel efficiency without sacrificing power which was appreciated during the era when gas prices were rising.
In 1987, GM transitioned to a new naming system using numbers like 10, 20, and 30 for their series—1500, 2500, and 3500 models emerged from this change. Despite these updates, the C1500 remains one of the most popular models today – under the name of Silverado.
This change in naming conventions reflected GM’s desire to simplify its lineup while still catering to various customer needs. The Silverado nameplate has since become synonymous with durability and performance in the truck market.
