Adding to the LTZ and Z71 models, the Silverado High Country (only offered as a Crew Cab) is distinguished on the outside by its unique chrome grille with horizontal chrome bars, halogen projector headlamps and color-coded bumpers. It also comes with standard 20-inch chrome wheels shod in P275/55R20 all-season tires, as well as chrome body side moldings, door handles and mirrors.
