Exterior - GMC Dealer serving Aurora, CO
The Sierra 2500 HD wears a purposeful, premium look that signals capability at a glance. A bold grille, high-clearance front fascia, and LED lighting with signature animated sequences on select trims project confidence day or night. Available trailering mirrors extend, retract, and fold at the push of a button and can add auto-dimming upper glass, auxiliary spot lamps, and perimeter lighting to improve sightlines when backing a trailer in a tight lot in Commerce City. Around back, the available six-function MultiPro™ Tailgate streamlines bed access with an integrated step, inner gate load stop, and work surface that transforms the tailgate into a task-ready platform. The spray-on bedliner with GMC logo is available to protect surfaces from repeated loading, while best-in-class HD cargo box volume and thoughtful tie-down points help secure unwieldy payloads. Choose from configurations that include a standard 6' 9" bed or an available 8' long bed to fit bigger tools and longer lumber. Attractive 17-, 18-, and 20-inch wheel designs—plus off-road-ready tires on AT4 and AT4X—add style and function, whether your route is a gravel site approach or a mountain pass.

Step into a cabin designed for long-haul comfort and all-day productivity. The Sierra 2500 HD provides best-in-class Crew Cab front head and leg room, so taller drivers and co-pilots settle in without compromise. Available 10-way power front seats with heat and ventilation on SLT, and 16-way power front seats with massage on premium models, dial up fatigue-fighting support on lengthy tows. Materials are thoughtfully chosen across the lineup—from durable appointments that shrug off dirt and dust to Denali-exclusive authentic open-pore wood and richly finished leathers. Dual-zone automatic climate control is available to tailor comfort for both sides of the cabin, while premium rear-seat leg room keeps Crew Cab backseat passengers happy on every run from Lakewood to the foothills. Technology is front and center with the available 13.4-inch diagonal GMC Premium Infotainment System with Google built-in, a crisp 12.3-inch digital Driver Information Center, and an available Bose® Premium Sound System that turns the cabin into a rolling control room. Add the Rear Camera Mirror and multicolor 15-inch Head-Up Display where equipped, and key information remains in sight without pulling focus from the road.
GMC Sierra 2500 HD Mechanical specs
Under the sheet metal, the Sierra 2500 HD leverages a robust ladder frame, heavy-duty axles, and the confidence of the Allison® 10-speed automatic to put power to the ground smoothly and predictably. The Traction Select System with Tow/Haul mode helps tailor throttle mapping and shift logic based on load and surface, and available off-road suspension hardware—such as twin-tube Rancho® shocks and skid plates with the X31 Off-Road package—bolsters control on rutted approaches and muddy work areas. Select models add a rear electronic-locking differential for consistent traction when one wheel lifts on uneven terrain. With ground clearance around 10.1 inches and a wheelbase stretching up to 172.0 inches, the Sierra 2500 HD remains composed at speed and stable under load. The ProGrade® Trailering System integrates with the In-Vehicle Trailering App to streamline pre-departure checklists, maintenance reminders, and trailer profiles. Between the standard bed’s generous cargo capacity and the long bed’s available 83.5 cubic feet, you’ll carry more and make fewer trips. For shoppers near Aurora, CO, who need a truck that feels unflappable with a loaded bed and a steep climb ahead, our Sierra 2500 HD configurations deliver the durable foundation your work demands.
Powertrain - GMC Dealership near Aurora, CO
Two big engines define the Sierra 2500 HD playbook—both matched to the renowned Allison® 10-speed automatic. The standard 6.6L V8 gas engine provides robust power and broad torque, ideal for mixed city-highway use and frequent starts and stops. Step up to the available Duramax® 6.6L Turbo-Diesel V8 for confident hill climbs, sustained towing, and relaxed highway rpm when the trailer is in tow. Properly equipped, Sierra 2500 HD achieves a max available conventional trailering rating of 20,000 pounds and a max available gooseneck/fifth-wheel rating of 21,870 pounds, supported by a 30,000-pound max GCWR. Available 2WD and 4WD drivetrains, a choice of Crew Cab with standard or long bed, and integrated Tow/Haul calibration let you tailor the truck to frequent payloads and typical routes. The In-Vehicle Trailering App stores trailer profiles—like brake gain and tire pressure—and anchors checklists right on the center screen, while available Adaptive Cruise Control with trailering accounts for drag and longer braking distances to help maintain a set gap. Whether daily hauling on the Front Range or weekend towing into the high country, the Sierra’s powertrains are tuned for confidence and control.
Safety - 2025 GMC Sierra 2500 HD dealer
Every Sierra 2500 HD includes Sierra HD Pro Safety, a suite of active features designed to assist in day-to-day driving and low-visibility trailering. Standard Forward Collision Alert, Automatic Emergency Braking, and Front Pedestrian Braking provide helpful alerts and support when traffic changes quickly. Lane Departure Warning and a Following Distance Indicator help keep spacing and lane discipline on crowded interstates, while IntelliBeam auto high beams optimize night driving without constant stalk inputs. Up to 13 or 14 available camera views—depending on configuration—can include HD Surround Vision, Bed View Camera, and the industry-first available Transparent Trailer View to help visualize conditions around your payload and hitch. An available Rear Camera Mirror expands rearward awareness, and available OnStar services bring enhanced support for road incidents. With the ProGrade® Trailering System, pre-departure safety checks become second nature, and available trailer tire pressure and temperature monitoring adds another layer of confidence. At Alpine Buick GMC, our team will demonstrate how these systems work together so you can confidently match features to your needs and tow with the assurance that the truck is working as hard as you are.
