Along with single or tandem axle configurations, the GMC Crackerbox was available with a sleeper cab. Alongside a 702 cubic-inch GMC V12 gasoline engine, the truck was available with the Detroit Diesel 6V71 and 8V71 engines. Distinguished by its boxy appearance, it earned the nickname "Crackerbox." Available in a 48-inch BBC (bumper to back of cab) length, the truck was produced with an all-aluminum fully tilting cab. In 1959, GMC introduced its Class 8 cabover trucks, replacing the previous " Cannonball" fixed-cab cabovers. Throughout the entire production run, the trucks were assembled in Pontiac, Michigan by the Pontiac Central Assembly facility.


As of current production, GM has not marketed another Class 8 cabover truck (as the configuration has effectively ended production in North America). In 1986, General Motors created the Volvo–GM joint venture with Volvo Trucks, leading to the discontinuation of the Astro in 1987. Succeeding the F/D-series "Crackerbox" cabovers, the Astro was marketed by Chevrolet as the Titan, serving as the largest cabover trucks ever produced by General Motors.įollowing the 1980 model year, Chevrolet exited the heavy-truck segment thereafter, alongside the Brigadier and General conventionals, the Astro was marketed solely under the GMC brand. The GMC Astro (also known as the Chevrolet Titan) is a heavy-duty ( Class 8) cabover truck that was manufactured by the GMC Truck and Coach Division of General Motors from the 1969 to 1987 model years.
