2015 Chevrolet Silverado HD pictures Photo 2 of 18

The Chevrolet Silverado HD is the less expensive of two offerings from General Motors -- the other being the GMC Sierra HD -- with a choice of two engines and three cab configurations. The Silverado HD is offered in 2500 and 3500 series, with either a single rear axle or dually configuration, and a multitude of trims. A new top-level trim, High Country, will be available later in the year.
