What was the last year Square Body Chevy truck?

The last year for the Square Body Chevy pickup was 1987. The square-body C/K line ran from 1973 through 1987, ending before GM introduced the GMT400-based trucks for 1988. This article details the historical context, the significance of 1987, and what followed in GM's pickup lineup.

Defining the Square-Body Era

To understand why 1987 is considered the end of an era, here are the defining characteristics of the Square Body and how the transition to the next generation occurred.

• The term "square body" refers to Chevrolet and GMC pickups produced roughly from 1973 to 1987, recognizable by squared-off fenders and a boxy overall silhouette.


• The 1973 redesign introduced a modern, durable body style that became iconic for the C/K line across many model years.


• In 1988 GM introduced the GMT400 platform, a new generation with updated styling and chassis, marking the end of the square-body era.

These points identify the boundary between the Square Body era and the subsequent GMT400 generation, which began with the 1988 model year.

1987: The Final Year

In the 1987 model year, Chevrolet and GMC continued selling the familiar square-body C/K pickups, but engineers were already executing the transition plan that would redefine GM trucks in 1988. For collectors, the 1987 trucks are notable as the last of the classic square-body styling.

What changed with the 1988 GMT400?

The 1988 model year introduced the GMT400 family, a comprehensive redesign featuring a different, more modern chassis, redesigned sheet metal, and updated interiors. While the GMT400 retained the C/K branding in early years (as Silverado/Sierra), the styling and engineering signals marked a clear break from the classic square-body look.

Collector's Perspective

Today, 1987 square-body pickups are sought after by enthusiasts for their historical significance and relative rarity in good condition. They represent the last era before GM’s major redesign altered the silhouette of its light-duty pickups for decades to come.

Summary

The last year of the Square Body Chevy truck was 1987. GM then moved to the GMT400-based design for 1988, ending the era and ushering in a new generation of C/K pickups. For collectors and historians, 1987 carries the weight of a transitional moment in American automotive design.
