The Chevrolet K1500 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 K10, K20, and K30 to designate their four wheel drive 1/2, 3/4, and 1 ton trucks, the 4th Gen C/K introduced a new naming system that replaced the K10 with the K1500. The 1/2 ton, four wheel drive K1500 was available with a selection of engines that included a standard 4.3L V6, alongside 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 K1500 was also offered in a range of trims, including the top of the line Silverado. Notably, the Z71 Off-Road Package was only offered on the K1500. Production of the 4th Gen Chevrolet K1500 ended in 1999, when the new Chevrolet Silverado trucks were introduced.
