The Chevrolet Titan and GMC Astro are heavy-duty (Class 8) cabover trucks that were manufactured by the GMC Truck and Coach Division of General Motors. The largest cabover trucks ever produced by GM, the Titan (and more common Astro) were introduced for 1969, replacing the 1960-1968 GMC "Crackerbox" COEs. The Astro and Titan would become the final trucks of the type assembled and marketed by General Motors, following the 1981 exit of Chevrolet from heavy truck sales and the 1986 creation of the Volvo GM joint venture. The Chevrolet Titan and GMC Astro were assembled at Pontiac Truck & Coach/Truck & Bus (Pontiac East Assembly) in Pontiac, Michigan, with the final GMC Astro produced in 1987.
