What's New

The 1999 GMC K1500 is a complete redesign from the ground up, which includes more powerful engines, better handling, a smoother ride, and improved brakes. In addition, GMC changed every aspect of the truck’s exterior design.


The dimensions of the 1999 GMC K1500 vary, depending on cab and bed size. A regular cab model with a short bed has approximately a 203-inch length, 78-inch width, 71-inch height, and 119-inch wheelbase. Extended cab models with short beds have a length and wheelbase that is 24 inches more. Long beds add about 19 inches to the length. The design of these pickups is comparably attractive to trucks offered by Ford and Dodge. They have a mean and aggressive stance. The K1500 features a chrome front bumper, chrome trim on the side of its body, externally adjustable door mirrors, daytime running lights, a rear platform step, tinted glass on its cabin, rear, and side. Two doors come standard with the option of a third rear door.


The interior of the 1999 GMC K1500 regular cab is roomy enough to fit three passengers, while extended cab models can accommodate up to six passengers. Features may vary, depending on model and cab size. In the front, there is a reclining cloth 40/20/40 bench seat with two height-adjustable headrests and a fold-down armrest in the center. The dash contains gauges that are arranged logically, conveniently-located controls, two integrated cup holders, and two mounted auxiliary power outlets. Extended cab models have a folding bench seat in the rear that fits three people. The K1500 features a simulated leather steering wheel, power windows and locks, passenger assist handles, vehicle lockout protection, and an AM/FM stereo that includes a digital clock. Heated front seats, a CD player, and an overhead console are optional.

Performance & Handling

The 1999 GMC K1500 comes standard with a 4.3-liter six-cylinder engine that produces 200 horsepower and 260 lb-ft of torque. Five powerful V-8 engines are also available, including a turbocharged diesel. Horsepower ranges from 230 to 270. Maximum torque, 440 lb-ft, is produced from the diesel motor. The engines are combined with either a five-speed manual or four-speed automatic transmission. This pickup offers a maximum towing capacity of 8000 pounds.

The K1500 is built with an independent wishbone front suspension with a stabilizer bar and torsion springs teamed with a rigid beam rear suspension with leaf springs. This setup provides for a smooth and firm ride. Four-wheel drive makes off-roading a cinch. The K1500 handles adequately, maneuvering easily in traffic and taking sharp corners nicely. Steering is predictable, allowing for precise control and manageability.


The 1999 GMC K1500 is equipped with anti-lock brakes on all four wheels. There are driver and front passenger front-impact airbags installed. The NHTSA gives the K1500 acceptable crash test ratings for passenger protection during front and side-impact collisions.
