Source: General Motors, 2026 GM Fleet Guide. Body and weight tables visually reviewed. Rounded fleet-guide wheelbases retained as published. Towing maxima remain sourced to dedicated trailering charts where available; the fleet guide's Silverado 1500 towing engine footnotes conflict with its overview.

Bed, tongue weight, and wheelbase
The trailer rating is one limit. The bed has to fit the load, the tongue or pin has to fit in payload, and the wheelbase is the column the chart uses.
- An illustrative 10 percent of the 20,000 lb conventional maximum is 2,000 lb of tongue weight. This is not a measured load or recommended percentage; actual load may be higher. The payload figure on file is 4,101 lb, and it is not the same truck unless the configurations match.
- An illustrative 15 percent of the 22,420 lb gooseneck maximum is 3,363 lb of pin weight. This is not a measured load or recommended percentage; actual load may be higher. The payload figure on file is 4,101 lb, and it is not the same truck unless the configurations match.

Generation
T1XX HD
2026 is year 7 of this generation (2020–2026). Current Silverado 2500HD. A 2024 update raised Duramax output and made the 10-speed the diesel transmission. The cited maximum on file is the 2025 Kelley Blue Book configuration, not a 2026 cell.

What changes the number
- Engine and transmission
- Cab, bed, and wheelbase
- Two-wheel drive, four-wheel drive, or all-wheel drive
- Axle ratio and tow package
- Conventional hitch versus fifth-wheel versus gooseneck
- People, options, and cargo, which spend payload the chart assumed was empty
Questions
- How much can a 2026 Chevrolet Silverado 2500HD tow?
- The cited maximum for a 2026 Chevrolet Silverado 2500HD is 20,000 lb conventional, 22,420 lb gooseneck. Crew Cab with 6.6L Duramax diesel and Max Trailering Package; see cab/drive rows and footnotes 3–4 on page 129.
- Did Silverado 2500HD towing change for 2026?
- Compare the cited 2026 figures on this page with the 2025 record. They are stored separately.
- Which configuration hits the maximum?
- Regular Cab 2WD long box, 6.6L Duramax diesel, Max Trailering Package and gooseneck hitch; page 129 footnote 5.
- What tongue weight should I plan for a 2026 Silverado 2500HD?
- At the cited 20,000 lb conventional maximum, an illustrative 10% assumption produces 2,000 lb of tongue weight. This is not a recommended percentage or a measurement; follow your trailer and vehicle instructions and measure the actual load. At the cited 22,420 lb gooseneck maximum, an illustrative 15% assumption produces 3,363 lb of pin weight. This is not a recommended percentage or a measurement; follow your trailer and vehicle instructions and measure the actual load. That load counts against payload and the rear axle rating.
