Why You’ll Love This Sierra 1500

The AT4 sits near the top of the Sierra 1500 lineup, landing above the SLT and below the Denali within GMC’s trim structure, blending confident trail capability with its Traction Select System with Off-Road mode, World's First Six-Function GMC MultiPro Tailgate, and leather-appointed heated and ventilated front seats for everyday comfort.
