Put serious diesel muscle and Denali luxury in your driveway with this 2025 GMC Sierra 3500HD Denali Crew Cab 4x4. The Sterling Metallic exterior, chrome accents and 20-inch high-gloss black aluminum wheels give this GMC a sharp look that stands out from every angle.

Four-wheel drive, a two-speed electronic Autotrac transfer case, an automatic-locking rear differential and a 3.42 rear axle round out the drivetrain.

This Denali gives you plenty of reasons to put your next trip on the calendar. Inside, heated and ventilated front seats, heated rear outboard seats and a heated wrapped steering wheel make the cabin welcoming year-round. The 12-way power driver’s seat, driver-seat and mirror memory, and dual-zone automatic climate control help you get comfortable quickly. The Denali Reserve Package adds a power sunroof, rear camera mirror and multicolor 15-inch head-up display. Open the sunroof, settle into the leather seat and see how enjoyable a heavy-duty truck can be. The Premium GMC Infotainment System features a 13.4-inch color touchscreen with Google built-in compatibility, navigation capability, Bluetooth and wireless Apple CarPlay and Android Auto for compatible phones. Bose premium speakers provide the soundtrack, while wireless charging keeps your compatible phone powered without the extra cord. A 12.3-inch reconfigurable driver display and Adaptive Cruise Control add convenience on longer drives, and 120-volt outlets in the cab and bed put useful power within reach. HD Surround Vision, front and rear parking assistance, Trailer Side Blind Zone Alert and Rear Cross Traffic Alert help you keep track of your surroundings.
