What Is a G-Body?

The G-Body platform is a type of mid-size, rear-wheel drive car platform that General Motors produced from the late 1970s to the late-1980s. They came in 2 door coupes, 4 door sedans, stations wagons, and trucks. The G-Body name comes from the platform code that General Motors used to identify these cars during their production. These cars were designed to be affordable and practical while also offering a fun and sporty driving experience.

One of the reasons that G-Body cars remain popular with enthusiasts today is their versatility. These cars can be modified and customized in a variety of ways, making them ideal for drag racing, autocross, or show car competitions. G-Body cars are also known for their distinctive styling, which often includes sharp angles, sleek lines, and bold colors. Whether you’re a die-hard G-Body fan or simply appreciate classic American cars, the G-Body platform is an important part of automotive history that continues to capture the hearts and minds of car enthusiasts around the world.

G-Body vehicles, as I know them, are 1978-1988, though 1978-1981 vehicles are “A-Body” cars and share a large percentage of the same parts.
