Todays truck enthusiasts refer to the different generations of Chevrolet® full-size pickups with various nicknames, and this style Silverado® is known as the NBS (New Body Style). When it was introduced, the 99 Chevy® Silverado® 1500 boasted all-new styling, all-new Vortec V-8 engines, and an all-new frame design with a state-of-the-art hydroformed forward section. Other new standard features included a passenger-side rear door on extended-cab models, along with four-wheel disc brakes.
