Chevy Silverado 2500HD & 3500HD Towing Specs Chart
Silverado 2500HD & 3500HD Towing Specs Matrix
When you tow heavy machinery, guessing isn't an option. Use our comprehensive towing data matrix to determine exactly which Silverado HD configuration has the GCWR to handle your trailers.
How much can a Chevy 3500 dually tow?
A properly equipped Chevy Silverado 3500HD Dually (DRW) powered by the 6.6L Duramax Turbo-Diesel engine paired with the Max Trailering Package can tow up to 36,000 pounds using a gooseneck or 5th-wheel hitch. Conventional towing maxes out at 20,000 pounds.
How to Read These Towing Charts
Towing capacity is dictated by four main factors: Engine (Gas vs. Diesel), Cab Size (Regular, Double, Crew), Drive Type (2WD vs. 4WD), and Hitch Type (Conventional vs. 5th-Wheel).
Your truck might be rated to tow 20,000 lbs, but if your 5th-wheel pin weight exceeds the truck's rear Gross Axle Weight Rating (GAWR) or total payload capacity, you cannot safely tow that trailer. The 3500HD Dually exists primarily to handle massive pin weights.
Silverado 2500HD Towing Matrix
The 2500HD is designed for heavy duty hauling without the width restrictions of a dual rear wheel setup. Note: Max capacities reflect optimal configurations (typically Regular Cab, 2WD, Max Trailering Package). Crew Cab 4x4 numbers will be slightly lower due to increased truck curb weight.
| Engine | Max Conventional Towing | Max 5th-Wheel / Gooseneck | Max Payload |
|---|---|---|---|
| 6.6L V8 Gas | 16,000 lbs (with Max Trailering) | 18,700 lbs | 3,759 lbs |
| 6.6L Duramax Turbo-Diesel | 20,000 lbs | 22,500 lbs | 3,615 lbs |
* Payload drops on diesel models because the diesel engine is significantly heavier than the gas engine.
Silverado 3500HD Towing Matrix (SRW vs DRW)
The 3500HD steps up capability, primarily by dramatically increasing payload and rear axle weight ratings, especially in the Dual Rear Wheel (DRW) configuration.
| Configuration & Engine | Max Conventional Towing | Max 5th-Wheel / Gooseneck | Max Payload |
|---|---|---|---|
| 3500HD SRW Gas | 16,000 lbs | 18,900 lbs | 4,682 lbs |
| 3500HD SRW Diesel | 20,000 lbs | 21,600 lbs | 4,185 lbs |
| 3500HD DRW Gas | 16,000 lbs | 18,700 lbs | 7,234 lbs |
| 3500HD DRW Diesel | 20,000 lbs | 36,000 lbs (Reg Cab 2WD) | 6,532 lbs |
The Gas vs. Diesel Towing Decision
Choosing your engine completely changes the character and capability of your heavy-duty truck.
- Choose 6.6L Duramax Diesel if: You tow over 15,000 lbs regularly, pull heavy 5th wheels, drive high annual highway miles, or operate in high elevations where gas engines lose power.
- Choose 6.6L V8 Gas if: You prioritize maximum payload (gas engines weigh less), operate locally with shorter trips, want lower upfront costs, and tow under 14,000 lbs.
