The Chevrolet C3500 was a variant of the 4th Gen Chevrolet C/K that debuted for the 1988 model year. Whereas for previous generations of the C/K, Chevrolet had used C10, C20, and C30 to designate their rear wheel drive 1/2, 3/4, and 1 ton trucks, the 4th Gen C/K introduced a new naming system that replaced the C30 with the C3500. The 1 ton, rear wheel drive C3500 was available with a selection of engines that included a standard 5.7L V8, alongside larger optional gasoline or diesel V8 units. These engines were paired with manual or automatic transmissions. Both a short (6.5 feet) and long (8 feet) truck bed were available, with either the sleek Fleetside or new Sportside bedside. The Sportside bed replaced the previous Stepside bed and was only available on the 6.5 foot bed. The C3500 was also offered in a range of trims, including the top of the line Silverado. The 4th Gen Chevrolet C3500 was the final 4th Gen C/K variant offered, with the cab chassis C3500HD exiting production in 2002, with these trucks replaced by the Chevrolet Silverado.
