Chevy Silverado 2500HD and 3500HD Towing Capacity by Year and Configuration

How much can a Silverado HD tow, year by year

The column below is the highest trailer weight Chevrolet or GM published for that model year, across both the 2500 HD and the 3500 HD. Conventional, bumper-hitch towing is a separate and much lower number: it was capped at 20,000 lb from 2016 through 2019 and again from 2021 to 2026, and it was always a 3500 HD with dual rear wheels until 2024.

Where the rows come from: 2016 to 2019 from GM's Chevrolet/GMC Duramax Diesel Supplements, which print one maximum trailer weight per truck and then cap conventional-hitch towing by footnote; 2020 from Chevrolet's 2020 Silverado 2500 HD trailering chart, with no 2020 3500 HD chart published on a Chevrolet site, so that row is a 2500 HD figure; 2021 from Chevrolet's 2021 Silverado 3500 HD chart; 2022 to 2026 from the Chevrolet Trailering Guide for each of those years, including the 2024 guide and the 2025 guide. For 2023 the gooseneck figure drops to 35,000 lb without the Max Trailering Package, and to 35,500 lb for 2024 to 2026.

Can it pull a big travel trailer or fifth wheel?

For a travel trailer the trailer rating is rarely what stops you. What stops you is payload: everything the truck carries, including the weight the trailer puts on the hitch. GM's 2026 fleet guide lists a maximum payload of 4,101 lb for the 2500 HD (Regular Cab, 8-foot box, 2WD) and 7,237 lb for the 3500 HD (same cab and box with dual rear wheels), and both are gas-engine figures.

Chevrolet says a conventional trailer should put 10% to 15% of its loaded weight on the hitch, and a fifth wheel or gooseneck 15% to 25% on the kingpin. A 12,000 lb travel trailer at 12% therefore lands about 1,440 lb on the hitch (12,000 × 0.12, calculated from Chevrolet's own percentage range), and that comes out of payload before any passengers, fuel cans, generators or bed cargo.

Which 2026 Silverado HD gets the top rating

Every top figure for 2026 needs the Duramax diesel. The gas V8 does not appear in any of these rows. If you are buying for a fifth wheel hitch or a gooseneck ball, the cab, box, drive and rear-wheel choice decides as much as the engine does.

Figures from the 2026 Chevrolet Trailering Guide linked above; its 2500 HD table prints one combined fifth-wheel and gooseneck column, so those two are not split for that truck. GM's own 2026 publications give three different 2500 HD maximums, 22,050 lb in the trailering guide, 22,420 lb in the fleet guide and 22,070 lb on chevrolet.com, and this table follows the trailering guide. For every cab, box and axle combination, work through Chevrolet's own trailering charts.

2500 HD or 3500 HD?

On a bumper hitch they are the same truck: 20,000 lb each for 2026, and the 2500 HD has only reached that figure since 2024. The gap opens over the bed. The 2500 HD tops out at 22,050 lb on a fifth wheel or gooseneck; the 3500 HD reaches 32,000 lb and 36,000 lb, and it is the only one of the two offered with dual rear wheels.

The 3500 HD also carries far more. Its dual-rear-wheel trucks are rated at a gross vehicle weight of 14,000 lb against a 2500 HD maximum of 11,900 lb, which is why the payload gap is close to 3,000 lb. Chevrolet puts it plainly: a higher series number usually means a stronger frame, stiffer suspension and higher-capacity brakes. If none of these loads are near what you pull, a half-ton Silverado 1500 is the cheaper truck to live with.

Gas or Duramax?

For 2026 the 6.6L V8 gas engine peaks at 18,700 lb conventional on a 3500 HD Regular Cab long bed 2WD with dual rear wheels, and at 19,080 lb on a gooseneck or fifth wheel on the same cab and bed with single rear wheels. In a 2500 HD the gas engine stops at 16,000 lb conventional. The Duramax reaches 20,000 lb conventional and the 32,000 lb and 36,000 lb bed-hitch figures.

Older trucks were tighter. From 2016 to 2018 the gas engine was the 6.0L V8, good for 14,500 lb conventional and 14,800 lb on a fifth wheel with the 4.10 axle, and no gas rating for the 2019 HD was found in a GM document. A 2500 HD Duramax of that era was held to 13,000 to 15,000 lb on a conventional hitch by the supplement footnotes, whatever its 18,100 lb table figure said.

GMC's heavy duties share the same engines and the same GM documents. A GMC Sierra 1500 is a half ton and rated well below all of this, as is the Ram 2500's smaller sibling; read Ram figures only from Ram's own towing documents.

Hitch, trailer brakes and weight distribution

Chevrolet's 2026 guide calls for trailer brakes above a 2,000 lb trailer weight, and GM's 2026 HD towing supplement says the same thing with one addition: brakes on each axle, with state rules on top. The integrated trailer brake controller is available on the Silverado HD rather than standard, so check the build before you count on it.

A weight-distributing hitch is optional on these trucks up to 20,000 lb of trailer, at 25% hitch distribution, and the guide footnote states outright that a frame-mounted weight-distributing hitch is not required on a 2500 HD or 3500 HD. One exception is written into the supplement: trucks with on/off road or mud terrain tires need one with any trailer over 10,000 lb.

The 2500 and 3500 come with a 2.5-inch square receiver and an adapter for a 2-inch draw bar. No 2026 document publishes a fixed receiver capacity, so read the label on the receiver itself, and take the maximum tongue weight for both hitch types from the truck's trailering label. The 2016 to 2018 owner manuals did print fixed limits:

• Conventional tongue weight: 1,500 lb with the standard box, 2,000 lb with the long box
• Fifth-wheel or gooseneck kingpin: 3,000 lb on a 2500
• Kingpin on a 3500: 4,000 lb with single rear wheels, 5,500 lb with dual rear wheels

Where your own truck's figure is

Two places give a figure that applies to your specific truck. The Trailering Information Label in the driver's door jamb lists its gross vehicle weight rating, combined rating, rear axle rating, maximum payload, maximum tongue weight and curb weight; GM's supplement calls the same label the B-pillar label. After that, find the row in that model year's trailering guide that matches your cab, box, drive, rear wheels, engine and wheel size, which is the step-by-step in the guide to finding your towing capacity.
