Powertrain - GMC Dealership near La Junta, CO

Two hardworking powertrains headline this lineup, both paired with a 10-speed automatic engineered to keep you in the heart of the power band whether you’re launching a loaded trailer or easing down a grade. The standard 6.6L V8 gas engine delivers dependable grunt and clean throttle response for daily duty, while the available Duramax 6.6L Turbo-Diesel V8 elevates confidence with exceptional torque, quiet refinement, and an integrated exhaust brake for enhanced downhill control. Tow/Haul mode and the Traction Select System collaborate to optimize shift strategy and traction characteristics, and the truck’s smart grade-braking logic helps maintain set speeds on long descents without excessive brake input. Select models equip an upgraded cooling strategy to manage heat during extended climbs and towing in hot conditions, and higher-capacity alternators support work-ready upfits and accessories. Whether you prefer the simplified fueling of a strong gas V8 or the long-haul efficiency and low-RPM muscle of the Duramax diesel, the 2026 GMC Sierra 3500 HD delivers a confident, quiet, and controlled drive. It’s the kind of power that feels unflappable in crosswinds, sure-footed pulling away from a stop, and unbothered as the miles roll on—exactly what heavy-duty ownership should feel like.
