Chevrolet’s official 2024 Trailering Guide publishes 56 base trailer-rating positions for Silverado 3500HD pickups, plus four High Country engine rows and one package-specific gooseneck exception. The ordinary table spans 14,500 to 35,500 lb. A Duramax Regular Cab long-bed 2WD dually reaches 35,500 lb with either a fifth-wheel or an otherwise un-packaged gooseneck; only the Work Truck with the Max Trailering Package and a gooseneck reaches 36,000 lb. The exact cab, drive, rear-wheel arrangement, engine, hitch and package therefore matter more than the model-line headline.
Direct answer: 35,500 lb is the base maximum; 36,000 lb is conditional
The highest conventional rating in the 2024 Silverado 3500HD pickup matrix is 20,000 lb. The highest ordinary in-bed result is 35,500 lb on the Duramax Regular Cab long-bed 2WD DRW row. Chevrolet prints separate fifth-wheel and gooseneck lines for that application, but both are 35,500 lb unless the gooseneck truck also satisfies the maximum-rating footnote.
The 36,000-lb result requires Work Truck trim, the available Max Trailering Package and a gooseneck hitch. It is not a universal diesel-dually rating and it is not the fifth-wheel value. Other configurations range down to 14,500 lb, so a badge or rear fender shape does not identify the correct number.
| 2024 endpoint | Configuration condition | Published rating |
|---|---|---|
| Lowest base rating | Multiple SRW conventional positions | 14,500 lb |
| Highest conventional | Selected Duramax and DRW rows | 20,000 lb |
| Highest SRW in-bed | Duramax Regular Cab long bed 2WD SRW | 22,430 lb |
| Highest fifth-wheel | Duramax Regular Cab long bed 2WD DRW | 35,500 lb |
| Gooseneck without Max Trailering | Same Duramax Regular Cab 2WD DRW | 35,500 lb |
| Gooseneck with Max Trailering | Same truck; WT and package required | 36,000 lb |
What Chevrolet publishes on numbered pages 37 through 40
The four Silverado 3500HD pages in Chevrolet’s 48-page guide cover Regular, Double and Crew Cab pickups. Its 14 base body and rear-wheel rows are each paired with the 6.6L gas V8 and 6.6L Duramax, producing 28 conventional and 28 combined gooseneck/fifth-wheel base positions. Two High Country configurations add four engine-specific rows.
Most in-bed cells intentionally combine fifth-wheel and gooseneck ratings. Those cells remain combined here. Only the marked Regular Cab 2WD DRW Duramax application supports a separate 36,000-lb package-specific gooseneck outcome.
| Published component | Count | How it is preserved |
|---|---|---|
| Base configuration rows | 14 | Cab, bed, drive and SRW/DRW retained |
| Conventional base positions | 28 | Gas and Duramax kept distinct |
| Combined in-bed base positions | 28 | Not split without printed support |
| High Country engine rows | 4 | Two 4x4 Crew Cab configurations |
| Maximum exception | 1 | 35,500 base / 36,000 WT-package gooseneck |
Crew Cab SRW ratings
Crew Cab SRW includes standard- and long-bed trucks in 2WD or 4x4. Gas conventional ratings are 16,000 lb and Duramax conventional ratings are 20,000 lb in the displayed base cells, subject to Chevrolet’s marked tire footnote. In-bed values still change by bed, drive and High Country equipment.
The highest Crew Cab SRW in-bed result is 22,070 lb for the long-bed 2WD Duramax. High Country is published as a separate 20-inch-wheel 4x4 row; it is not evidence for a universal trim deduction.
| Crew Cab SRW configuration | Gas conventional | Duramax conventional | Gas in-bed | Duramax in-bed |
|---|---|---|---|---|
| Standard bed 2WD | 16,000 | 20,000 | 18,650 | 21,900 |
| Standard bed 4x4 | 16,000 | 20,000 | 18,300 | 21,600 |
| Standard bed High Country 4x4 | 16,000 | 20,000 | 17,900 | 21,300 |
| Long bed 2WD | 16,000 | 20,000 | 18,510 | 22,070 |
| Long bed 4x4 | 16,000 | 20,000 | 18,230 | 21,510 |
| Long bed High Country 4x4 | 16,000 | 20,000 | 17,800 | 21,200 |
Crew Cab long-bed DRW ratings
The Crew Cab dually rows use the long bed. Duramax conventional ratings are 20,000 lb, while their combined in-bed values are 31,450 lb for 2WD and 31,000 lb for 4x4. The gas rows remain below those diesel values and can have an in-bed rating close to or slightly above the conventional rating.
High Country appears as its own 4x4 DRW row: 17,600 lb for both gas hitch methods and 20,000 lb conventional versus 30,900 lb in-bed with the Duramax. That exact row should not be applied to another trim, cab or driveline.
| Crew Cab long-bed DRW | Gas conventional | Duramax conventional | Gas in-bed | Duramax in-bed |
|---|---|---|---|---|
| 2WD | 18,200 | 20,000 | 18,240 | 31,450 |
| 4x4 | 17,800 | 20,000 | 17,800 | 31,000 |
| High Country 4x4 | 17,600 | 20,000 | 17,600 | 30,900 |
Double Cab long-bed ratings
Every Double Cab row in the matrix uses the long bed. SRW conventional ratings are 16,000 lb with gas and 20,000 lb with the Duramax, while combined in-bed ratings vary from 18,310 to 21,900 lb according to drive and engine. The QG3 mud-terrain footnote must still be checked wherever Chevrolet marks a conventional cell.
Dually ratings move higher with the Duramax: 31,580 lb in-bed for 2WD and 31,280 lb for 4x4. Neither value can stand in for the Regular Cab maximum branch.
| Double Cab long-bed configuration | Gas conventional | Duramax conventional | Gas in-bed | Duramax in-bed |
|---|---|---|---|---|
| 2WD SRW | 16,000 | 20,000 | 18,620 | 21,900 |
| 4x4 SRW | 16,000 | 20,000 | 18,310 | 21,590 |
| 2WD DRW | 18,300 | 20,000 | 18,300 | 31,580 |
| 4x4 DRW | 18,000 | 20,000 | 17,990 | 31,280 |
Regular Cab ratings and the Max Trailering footnote
Regular Cab is long-bed only in this pickup table. The 2WD SRW Duramax reaches 22,430 lb in-bed, while its gas partner is 19,080 lb. The 2WD DRW Duramax row is the sole place where the package footnote creates the 36,000-lb exception.
For that dually, Chevrolet publishes 35,500 lb on both the fifth-wheel line and the ordinary gooseneck line with a 43,500-lb GCWR. A second gooseneck line uses 43,900-lb GCWR and 36,000 lb, but the footnote requires WT with the Max Trailering Package and reduces the result to 35,500 lb without it. The 4x4 Duramax dually remains 31,500 lb in-bed.
| Regular Cab long-bed configuration | Gas conventional | Duramax conventional | Gas in-bed | Duramax in-bed |
|---|---|---|---|---|
| 2WD SRW | 14,500 | 14,500 | 19,080 | 22,430 |
| 4x4 SRW | 14,500 | 14,500 | 18,700 | 22,050 |
| 2WD DRW | 18,700 | 20,000 | 18,760 | 35,500 FW/GN / 36,000 GN with WT + package |
| 4x4 DRW | 18,400 | 20,000 | 18,380 | 31,500 |
GVWR, GCWR and the tire alternative are selectors—not trailer ratings
The 2024 table pairs truck-specific GVWR values with 26,000-, 30,000-, 40,000-, 43,500- and 43,900-lb GCWR branches. GVWR limits the loaded truck; GCWR limits the loaded truck and trailer together. Neither can be substituted for the trailer-weight column.
Chevrolet’s QG3 footnote reduces marked conventional cells to 12,000 lb when the truck has 18-inch mud-terrain tires. Keep that alternative beside the printed base result; do not overwrite an unmarked cell or carry the footnote to a different wheel and tire row.
| 2024 branch | GVWR | GCWR | What it distinguishes |
|---|---|---|---|
| Gas SRW | 10,950–11,700 lb | 26,000 lb | Cab, bed and drive-specific gas row |
| Duramax SRW | 11,500–12,250 lb | 30,000 lb | Diesel SRW combination |
| Gas or most Duramax DRW | 14,000 lb | 26,000 or 40,000 lb | Engine-specific dually branch |
| Regular 2WD DRW fifth-wheel/base gooseneck | 14,000 lb | 43,500 lb | 35,500-lb outcome |
| Regular 2WD DRW package gooseneck | 14,000 lb | 43,900 lb | 36,000 lb only with WT and package |
Hitch load can consume the truck’s payload first
Chevrolet recommends conventional trailer tongue weight of 10–15 percent of loaded trailer weight and gooseneck or fifth-wheel kingpin weight of 15–25 percent. At 20,000 lb conventionally, tongue weight alone can be roughly 2,000–3,000 lb before occupants, cargo and hitch hardware are added.
The guide says tongue or kingpin load cannot cause the truck to exceed GVWR or rear GAWR. Use the certification label, tire-and-loading label, hitch labels and scale tickets. A published 35,500- or 36,000-lb trailer rating does not prove that a particular truck has sufficient payload.
A repeatable way to match the truck
Confirm the 2024 model year, then record cab, bed, 2WD or 4x4, SRW or DRW, gas or Duramax, wheel and tire row, trim and hitch. Check Max Trailering equipment only after those identifiers agree. The 36,000-lb claim additionally requires Work Truck and a gooseneck hitch.
A Duramax badge, dually fenders or 3.42 axle ratio cannot prove the entire chain. Use a VIN-linked build record for factory equipment, the door labels for GVWR and axle limits, hitch documentation for the installed coupling and loaded scale tickets for the actual combination.
| Evidence to check | Decision it supports |
|---|---|
| VIN-linked build record | Cab, drive, engine, trim and Max Trailering equipment |
| Certification label | GVWR and front/rear GAWR |
| Tire-and-loading label | Vehicle-specific occupant and cargo allowance |
| Hitch and tire records | Coupling limit and any QG3 mud-terrain alternative |
| Loaded scale tickets | Actual truck, trailer and axle weights |
Exact-year evidence and visual reconciliation
The primary evidence is Chevrolet’s official 48-page 2024 Trailering Guide. The direct PDF was downloaded previously, SHA-256 hashed and completely text-extracted. For this target, numbered pages 37–40 were freshly inspected in the manufacturer PDF and visually reconciled across every Regular, Double and Crew Cab row, both High Country configurations, the QG3 tire note and the maximum-rating footnote.
That review prevents a quiet carry-over from 2023. The 2024 source changes many cells, moves the SRW GCWR branches to 26,000 and 30,000 lb, and raises the marked base fifth-wheel and gooseneck result to 35,500 lb. No 2023, 2025 or GMC number fills a 2024 position.

Canadian-use and commercial boundaries
The recovered guide is U.S.-market literature. It supports the exact 2024 configuration matrix but does not certify an unseen Canadian VIN, an altered truck or a completed work body. Canadian use still requires the truck’s own labels, build record and applicable operating requirements.
This specification guide does not rank reliability, estimate failure rates or diagnose condition. It also does not invent inventory, sellers, dealer counts, prices, financing or offers. The separate marketplace remains the commercial authority and may have no eligible listings.
Frequently asked 2024 Silverado 3500HD questions
Can every 2024 Duramax dually tow 36,000 lb? No. That result requires a Regular Cab long-bed 2WD DRW Work Truck, Max Trailering Package and gooseneck hitch. What is the fifth-wheel rating on the marked branch? It is 35,500 lb. Without the package, the gooseneck result is also 35,500 lb.
Is 20,000 lb the universal conventional rating? No; several SRW positions are 14,500 or 16,000 lb, and gas dually rows occupy their own range. Do 18-inch mud-terrain tires matter? Marked conventional cells fall to 12,000 lb under the QG3 footnote. None of the table values proves payload or a Canadian VIN rating.
