Designed to see big challenges as bigger opportunities, the 2012 GMC Sierra 1500 was engineered to exceed. Heavy-duty trailering equipment, chrome-clad 18-inch aluminum wheel and distinctive badging set Sierra All-Terrain apart from the rest. The famed Z71 Off-Road suspension, Rancho Tenneco shocks and an Eaton® automatic locking rear differential mean no matter how far away the job takes you, you're bound to make it back.
