The Sierra 3500 HD lineup ranges from hard-working utility to world-class luxury, ensuring a configuration for every driver.

Trim: Pro

It serves as the foundation. Durable and straightforward, it’s designed for drivers who need uncompromising strength. Standard features include the 6.6L gas V8, six-function tailgate, trailering hardware, and a 7-inch touchscreen with smartphone integration.

Trim: SLE

This adds refinement, with cloth seating, keyless open and start, and an upgraded infotainment system. The ProGrade™ Trailering System also becomes standard, offering trailer profiles and monitoring features that simplify demanding jobs.

Trim: SLT

It introduces leather-appointed seating, heated front seats, and power driver adjustments, along with chrome exterior accents and 18-inch aluminum wheels. Advanced trailering technology and additional camera views further enhance towing confidence.

Trim: AT4

It delivers off-road ability and rugged styling. An off-road suspension, skid plates, hill descent control, and all-terrain tires combine with exclusive black chrome accents and Jet Black with Kalahari interior detailing.

Trim: Denali

Denali sets a high standard for luxury. A signature Denali grille, 20-inch polished wheels, and chrome accents distinguish the exterior. Inside, open-pore wood trim, Bose® Premium audio, and a 13.4-inch infotainment display paired with a 12.3-inch driver cluster transform the cabin into a refined command center.

Trim: Denali Ultimate

It crowns the range with Vader Chrome trim, exclusive 20-inch Ultra-Bright machined wheels, and a MultiPro™ audio system integrated into the tailgate. Inside, Alpine Umber full-grain leather, 16-way power massaging front seats, and etched wood trim create a space unlike any other in the heavy-duty class.

The Sierra 3500 HD offers 2 robust powerplants. The standard 6.6L V8 gas engine generates 401 hp and 464 lbs.-ft. of torque, mated to an Allison®-certified 10-speed automatic transmission.

For maximum power, the 6.6L Duramax® Turbo-Diesel V8 delivers 470 hp and a massive 975 lbs.-ft. of torque. Dual rear-wheel configurations make the most of this power, delivering towing capacities among the best in the segment.

With towing up to 18,500 pounds when properly equipped with the gas engine—and significantly more with the diesel—the Sierra 3500 HD demonstrates why it is a benchmark in capability.

An advanced suspension system, selectable drive modes, and up to 15 available camera views for trailer monitoring create confidence in every maneuver. Whether navigating steep grades, hauling heavy farm equipment, or towing livestock trailers across central Ohio, the Sierra 3500 HD combines power with precision.

The Sierra 3500 HD’s interior is designed with size and utility in mind. Crew Cab models, especially, offer expansive rear-seat space with more than 43-inches of rear legroom and over 66-inches of shoulder room, ensuring passengers ride comfortably no matter the distance. Storage is equally impressive.

The cabin provides more than 70 cu. ft. of total passenger volume, complemented by smart storage solutions. A deep center console can hold laptops or tools, while clever under-seat bins and rear seatback compartments keep essentials organized. Large door pockets and multiple cupholders further enhance everyday usability, ensuring everything from work gear to weekend necessities has a place.

Seamless connectivity comes standard. Wireless Apple CarPlay® and Android Auto™, available wireless charging, and a Wi-Fi hotspot keep drivers connected on the go. Chevrolet’s ProGrade™ Trailering System introduces tools like trailer checklists, integrated diagnostics, and transparent trailer view, making complex tasks feel intuitive.

In Denali trims, the combination of the 13.4-inch infotainment display, 12.3-inch digital gauge cluster, and a head-up display places all vital information directly in the driver’s line of sight.

The Sierra 3500 HD comes standard with Forward Collision Alert, Automatic Emergency Braking, and Lane Departure Warning, forming a core safety foundation.

Available features such as Adaptive Cruise Control, Lane Change Alert with Side Blind Zone Alert, Rear Cross-Traffic Alert, and a Safety Alert Seat elevate driver awareness. Together with its high-strength frame, these systems ensure safety is never compromised.
