The Sierra 3500HD is built to work. Whether you're managing heavy loads or navigating challenging terrain, this truck delivers the foundation you need. The 6.6L V8 paired with a 6-speed automatic transmission provides the power required for serious hauling and towing applications.

Off-road capability comes standard with the X31 package, which includes skid plates for undercarriage protection, an off-road suspension setup, and Hill Descent Control technology that adds confidence when navigating steep downhill grades. The 4-wheel drive system ensures traction across varied surfaces and weather conditions.

Practical features enhance everyday functionality. The bed view camera displays directly in the rearview mirror, simplifying backing up and positioning cargo. Heated trailering mirrors with auto-dimming and power-adjustable capability provide visibility in all conditions. The spray-on bed liner protects your investment while maintaining the truck's profile and payload capacity.

Inside, the cabin provides comfort for long workdays or extended drives. Heated front seats, a heated steering wheel, and dual-zone climate control offset cold weather demands. The power-adjustable driver seat with lumbar support reduces fatigue during extended hours behind the wheel. SiriusXM satellite radio and the GMC infotainment system keep you connected throughout your route.

This Sierra has been serviced here and arrives with a clean Carfax report and free lifetime state inspections. A fresh trade with demonstrated service history, this truck represents a solid opportunity for buyers seeking proven capability and reliability in a heavy-duty platform.
