The standard 6.6L V8 gasoline engine produces 401 hp and 464 lbs.-ft. of torque. If you need maximum capability, the available Duramax® 6.6L Turbo-Diesel V8, delivering 470 hp and an impressive 975 lbs.-ft. of torque, is built for the long haul.
Both engines are paired with the Allison® 10-speed automatic transmission, engineered for smooth power delivery under heavy loads.

There’s a Silverado 2500HD built for all kinds of drivers:

• The WT (Work Truck) is engineered for demanding jobsites with durable materials, straightforward functionality, and the capability commercial drivers rely on every day. It features the Durabed with 12 tie-downs, the Trailering Package with vertical trailering mirrors, and an automatic locking differential.
• Custom adds bolder styling with 20” machined aluminum wheels with Grazen Metallic accents, power-adjustable trailering mirrors with heated upper glass, remote keyless entry, and additional convenience features while maintaining its hardworking nature.
• LT is a strong middle ground with a more connected cabin. It adds a 13.4” infotainment touchscreen, the power lock and release EZ Lift tailgate, chrome bumpers, and upgraded interior materials.
• LTZ moves into premium territory with leather-appointed seating, LED lighting, daytime signature running lamps, power-folding and extending trailering mirrors, an in-vehicle trailering app, and expanded driver assistance technologies.
• ZR2 is off-road-ready from the factory with a 1.5” lift, 35” mud-terrain tires, Multimatic DSSV™ dampers, skid plates, the Multi-Flex™ Tailgate, and a rear electronic locking differential.
• High Country crowns the lineup with unique, premium leather seating, heated rear seats, exclusive interior finishes, advanced technology including a Bed View Camera and Trailer Side Blind Zone Alert, and distinctive exterior styling that brings luxury to the heavy-duty truck segment.

The Silverado 2500HD is built around a robust frame and advanced suspension that inspire confidence when carrying heavy payloads or towing substantial trailers.
The V8 gas models can tow up to 19,080 lbs., while Duramax® Turbo-Diesel models increase maximum towing capacity to 22,070 lbs. Available 4-wheel drive, Trailer Sway Control, Transparent Trailer View, and up to 14 available camera views make maneuvering larger trailers more controlled and less stressful.

Crew Cab models seat up to 6 passengers and offer generous room for work crews or families. A large center console, under-seat storage, and thoughtfully designed compartments provide space for tools, equipment, and personal belongings.
From work-friendly, durable materials in the lower trims to sumptuous leather-appointed seating with custom stitching in the High Country, heated and ventilated front seats, and Jet Black perforated leather seats with Strike Yellow accents in the ZR2, there’s an interior to fit your crew and needs.

Many models are equipped with a 13.4” touchscreen with wireless Apple CarPlay®, wireless Android Auto™, Google Built-In, connected navigation, and voice controls. Available wireless charging, Bose® premium audio, and the my Chevrolet mobile app provides added convenience through remote vehicle functions and health monitoring.
With extensive integrated trailering technologies available to simplify hitching, towing, and monitoring your trailer, even the most inexperience towing driver will feel confident behind the wheel.

The 2026 Silverado 2500HD offers a comprehensive suite of driver assistance technologies to back you up and be a co-pilot for your drives. These include Forward Collision Alert, Automatic Emergency Braking, Lane Departure Warning, a Rear Vision Camera, Teen Driver technology, and multiple airbags throughout the cabin.
Additional driver assistance technologies become available with each trim level, such as a Head-Up Display, Front and Rear Park Assist—which is a welcome feature with a truck of this size—and HD Surround Vision. Wherever the road or path takes you, these systems have your back.
