We offer a spectrum of exterior personalities sculpted to match your ambition. The PRO wears its utilitarian nature boldly, with a straightforward grille and functional bed tie-downs that signal readiness for hard work. Ascending to SLE, the Sierra gains refined touches—a chromed grille surround and body-color bumpers that elevate its street presence. Elevation drowns its form in monochromatic paint, punctuated by gloss-black mesh grille inserts, LED fog lamps and 20-inch gloss-black wheels that whisper performance. The SLT shifts the dial toward luxury: chrome-accented door handles, bumpers and grille, plus available larger wheels that gleam under any sky. For those who chase the unbeaten path, the AT4 and AT4X trims raise ride height with a 2-inch factory lift, Rancho® monotube shocks and underbody skid plates—complete with aggressive wheel designs to match. At the pinnacle, Denali and Denali Ultimate crown the lineup with signature chromed grilles, wheel-to-wheel assist steps and available CarbonPro® composite beds, while the Ultimate dazzles further with Ultra-Bright 22-inch machined wheels.

Under the hood of each Sierra you’ll find a choice of four distinct powertrains, each calibrated for its task. The standard TurboMax™ engine unleashes 310 hp and best-in-class 430 lb-ft of torque, backed by a 10-speed automatic that bolsters towing up to 9,500 lbs. Stepping up, the Duramax® 3.0L Turbo-Diesel marries efficiency with stout torque via its 10-speed automatic, offering a harmonious balance of power and fuel economy. For traditionalists, the available 5.3L EcoTec3 V8 blends proven reliability with confident output, while the 6.2L EcoTec3 V8 provides muscular acceleration and ample pulling prowess for heavy-duty chores.

When capability matters, the Sierra demands attention. Best-in-class towing of up to 13,200 lbs is tamed through the intuitive ProGrade® Trailering System, which monitors sway, weight distribution and hitch alignment in real time. The world’s first six-function MultiPro™ Tailgate transforms bed access with six distinct configurations—step, load stop, inner gate and more—making loading and unloading an almost effortless ritual. Up to 14 available camera views, including hitch-guidance, ensure you harness every ounce of this truck’s capability with surgical precision.

Step inside and encounter an oasis of craftsmanship. Over 40 inches of combined driver-focused digital display put navigation, trailering data and multimedia at your fingertips, all rendered in high-resolution clarity. The spacious Crew Cab boasts best-in-class front head- and legroom, ensuring that even the longest hauls feel less punishing. Premium materials abound: open-pore wood, patterned aluminum inlays and perforated-leather seats with heating, ventilation and massaging options on select trims deliver a sanctuary that balances utility with indulgence. Ample concealed storage and cleverly integrated cubbies mean gear and gadgets stay out of sight but always within reach.

We believe confidence on the road is paramount. The available Super Cruise® hands-free driver assistance technology ushers in a new era of highway autonomy, backed by OnStar® connectivity and real-time mapping. The GMC Pro Safety suite layers forward collision alert, automatic emergency braking, lane-keep assist and more into a cohesive safeguard that anticipates hazards. Parking and low-speed maneuvering become stress-free ventures thanks to Front and Rear Park Assist and up to 14 camera views, anchoring your confidence in every tight spot.
