Wallace Chevrolet, your prefferred BRAMPTON, Ontario GMC Dealership!
GMC SIERRA HD has what it takes to handle the most challenging assignments. Sierra HD has more models with a higher payload capacity versus the competition at a ratio of over 2 to 1.** Just as important, GMC SIERRA HD’s brains match its brawn. Intelligent features like trailer sway control, hill start assist on single rear wheel models and a driver-selectable exhaust brake (with Duramax diesel engine) let you manage the heaviest loads and the biggest trailers with confidence, even on steep grades.
