At GMC, the engineers are never satisfied. That's precisely why they took the strongest, most powerful Sierra Heavy Duty pickups ever and used them as a starting point.
The new 2018 Sierra 2500HD and 3500HD take proven powertrains and the new standard in quiet, comfortable truck interiors, pickup-first technologies and cargo box innovations to produce a premium-duty breed of professional grade trucks.
It's just another example of what incredible thinking can help you achieve.
