The 2011 GMC Sierra 3500 HD DRW is a powerful, heavy-duty truck that is both comfortable and functional. Built for toughness and reliability, this truck comes equipped with 4-wheel antilock brakes, a suspension package that includes twin tube shock absorbers and a front stabilizer bar, and a full-boxed hydroformed front section. You'll always have all the power you need with this trim's beastly 6.0-liter, V8 Vortec engine.
When conditions get bad, this truck keeps going. It comes equipped with dual halogen composite headlamps so you're always able to keep your eyes on the road, and a Stabilitrak stability control system with Roll Avoidance (in the RWD models) to keep your tires firmly planted.
