Performance and Engine Specs
Chevrolet provides two immense V8 engines for the Silverado HD, both paired with the legendary Allison® 10-speed automatic transmission to ensure absolute reliability under extreme stress.
| Engine Configuration | Horsepower | Peak Torque | Standard Transmission |
|---|---|---|---|
| 6.6L V8 Gas | 401 hp @ 5,200 RPM | 464 lb-ft @ 4,000 RPM | 10-Speed Allison® |
| 6.6L Duramax® Turbo-Diesel V8 | 470 hp @ 2,800 RPM | 975 lb-ft @ 1,600 RPM | 10-Speed Allison® |
Relentless Commercial Torque
The standard 6.6L V8 gas engine delivers robust daily power, perfectly suited for construction sites and frequent mid-weight hauling. For drivers pulling massive multi-axle trailers, massive 5th-wheel campers, or heavily loaded livestock trailers through the Driftless Area, the available 6.6L Duramax Turbo-Diesel is the definitive choice. Generating 975 lb-ft of torque at a remarkably low 1,600 RPM, it provides the low-end pulling power required to get massive loads moving smoothly. The standard Allison 10-speed transmission features Tow/Haul mode and Auto Grade Braking, which utilizes engine compression to control downhill speeds on Highway 14 without burning up your brake pads.
Capabilities
The 2500 HD and 3500 HD are structurally designed to bypass normal limits, offering single-rear-wheel (SRW) and dual-rear-wheel (DRW) configurations.
| Capability Metric | 2500 HD Max Rating | 3500 HD Max Rating |
|---|---|---|
| Maximum Towing Capacity | Up to 22,500 lbs | Up to 36,000 lbs |
| Maximum Payload Capacity | Up to 3,850 lbs | Up to 7,290 lbs |
| Available Hitch Types | Conventional, 5th-Wheel, Gooseneck | Conventional, 5th-Wheel, Gooseneck |
Dominating Towing and Terrain
When properly equipped with the Duramax Diesel, dual-rear-wheels, and a gooseneck hitch, the 3500 HD reaches a staggering 36,000 lbs of towing capacity. If your work takes you far from the pavement, the Silverado HD ZR2 pairs this heavy-duty strength with extreme off-road hardware. The ZR2 equips specialized Multimatic DSSV dampers, a 1.5-inch factory suspension lift, a selectable electronic locking rear differential, and massive 35-inch Goodyear Wrangler MT tires to dominate deep mud and jagged work site terrain.

Configuring Your Command Center
The LT trim radically upgrades the interior technology, introducing a sprawling 13.4-inch center touchscreen and a fully digital 12.3-inch driver cluster. For professionals who practically live in their trucks, the LTZ adds perforated leather seating, ventilated front seats, and an advanced Hitch View camera. At the peak of refinement, the High Country surrounds you with premium leather, real wood accents, and a standard Bed View Camera to monitor your gooseneck connection or cargo load on the move.
Exterior Design and Utility
The Silverado HD is built around the Durabed, a class-leading cargo box manufactured from roll-formed high-strength steel. It features 12 standard tie-downs rated at 500 lbs each. Because heavy-duty beds are naturally taller, Chevrolet integrated CornerStep rear bumpers and side BedSteps to grant easy, secure access to your tools or 5th-wheel hitch. The available Multi-Flex Tailgate provides six unique functions, including a fold-down standing desk for blueprints and an easy-access step.
Technology and Trailering
Inside LT models and above, the massive 13.4-inch diagonal advanced color LCD display utilizes Google built-in compatibility, integrating Google Maps directly into the dashboard for route guidance. However, the most critical technology is aimed squarely at towing. The In-Vehicle Trailering App allows you to create custom profiles for different trailers, run automated light tests, and monitor trailer tire pressures. Paired with up to 14 available camera views—including the revolutionary Transparent Trailer view—navigating tight Boscobel intersections with a 30-foot trailer is completely stress-free. Let our finance experts build these advanced trailering cameras into your purchasing plan.
Safety Features and Driver Assist
Moving extreme weight requires extreme safety. Every Silverado HD includes Chevy Safety Assist, providing Forward Collision Alert and Automatic Emergency Braking. Because trailering changes vehicle dynamics, Chevrolet offers Trailer Side Blind Zone Alert, which extends the monitoring area of your blind spot sensors to account for the entire length of your trailer. Additional stability is maintained by StabiliTrak with Trailer Sway Control. Review the official structural data via the NHTSA crash safety portal, and schedule your routine maintenance with our heavy-duty service and calibration experts.
