2026 Chevrolet Silverado 3500 HD

The Silverado 3500 HD lineup spans from pure work utility to premium-grade execution. WT is configured for fleets and contractors who prioritize durability, easy maintenance, and straightforward functionality. LT adds a more comfortable cabin with expanded technology, including larger digital displays and available trailering aids that reduce fatigue during long hauls. LTZ moves firmly into professional-grade refinement, introducing leather seating, enhanced camera systems, and advanced trailering visibility that simplifies hitching and maneuvering heavy trailers. High Country sits at the top of the range, pairing the truck’s maximum capability with premium materials, open-pore wood trim, and the most comprehensive set of driver-assistance and trailering technologies available in the lineup.

Two powertrains define the Silverado 3500 HD’s performance envelope. The standard 6.6L gasoline V8 delivers dependable output for mixed-duty work cycles. For maximum capability, the available Duramax® 6.6L Turbo-Diesel V8 is paired with the Allison® 10-speed automatic transmission, producing up to 470 hp and 975 lbs.-ft. of torque. The combination is engineered for sustained load management, delivering smooth, controlled power during heavy towing and steep grade climbs.

Capability is the Silverado 3500 HD’s defining metric. Properly equipped models support up to 36,000 lbs. of maximum trailering with a gooseneck or fifth-wheel setup. Available features such as an integrated trailer brake controller, exhaust brake, and Tow/Haul mode with grade braking help maintain control on descents and during extended pulls. Dual-rear-wheel configurations increase stability under heavy loads, while high-capacity suspension components keep the truck composed on uneven job sites. Available Digital Variable Steering Assist lightens steering effort at low speeds and adds firmness at highway pace, improving control when maneuvering large trailers through tight areas or long stretches of road.

Inside, the Silverado 3500 HD balances space, durability, and technology. Crew Cab models offer ample rear legroom for full crews, while configurable storage solutions keep tools and gear secure. The cabin is anchored by an available 13.4-inch infotainment display paired with a 12.3-inch digital Driver Information Center; upper trims add an available 15-inch head-up display that places key trailering data directly in the driver’s line of sight. High Country trims elevate the experience with premium leather seating, heated and ventilated front seats, and refined materials that make long towing days more manageable. Wide door openings, durable touch points, and functional console layouts reinforce the truck’s work-first design.

Safety systems are designed to support heavy-duty operation. Standard features include StabiliTrak® electronic stability control, a rear vision camera, and a full airbag system. Available advanced driver-assistance technologies add Enhanced Automatic Emergency Braking, Lane Change Alert with Side Blind Zone Alert, Rear Cross Traffic Braking, HD Surround Vision, and Trailer Side Blind Zone Alert—critical tools when navigating busy worksites or town traffic with a load in tow.
