What is a Squarebody Truck

Squarebody trucks refer to a series of General Motors trucks that were built from 1973 to 1987. These trucks were characterized by their square-shaped design and sturdy frames, making them popular for both work and play. The squarebody truck series was eventually replaced by the GMT400 trucks.

The squarebody truck series was introduced in the early 1970s as an upgrade to the previous Task Force and Advance Design truck lines. The design incorporated a boxy look, with flat, angular lines. The rectangular grille featured a divided upper section – giving the appearance of a double grille – and square headlights.­

The squarebody trucks were versatile workhorses, used for a variety of tasks including hauling cargo and towing equipment. They were also popular among off-road enthusiasts, who appreciated their sturdy frames and spacious cabs.

Over the years, the squarebody truck series underwent several modifications and upgrades. In 1978, a diesel engine was added as an option, and in 1981, the four-wheel-drive system was upgraded with the introduction of the NP208 transfer case.

In 1987, the squarebody truck series was replaced with the GMT400 series. The GMT400 was a significant departure from the boxy look of the squarebody trucks, featuring smoother lines and rounded edges.

Despite being out of production for over 30 years, squarebody trucks remain popular among collectors and enthusiasts. Their classic design and durability make them a sought-after choice for restoration projects, and many are still in use as work trucks today.
