2019 Chevrolet Silverado 3500HD Towing Capacity & Payload

The 2019 Chevrolet Silverado 3500HD can tow a maximum of 23,100 pounds when properly equipped with the 6.6L Duramax turbo-diesel engine, a regular cab, dual rear wheels (DRW), two-wheel drive, and a gooseneck or fifth-wheel hitch. As Chevrolet’s flagship heavy-duty workhorse for the 2019 model year, the 3500HD delivers incredible capability, utilizing SAE J2807 towing standards to provide accurate and reliable ratings for heavy haulers.

Whether you are pulling a massive toy hauler, a multi-car trailer, or heavy construction equipment, the Silverado 3500HD has the hardware to get the job done safely. Always remember that exact capacities vary wildly depending on cab size, bed length, drivetrain, and axle ratio.

Quick answer

• Max Tow Capacity: 23,100 lbs (5th-wheel/gooseneck) / 20,000 lbs (conventional)
• Max Payload: 7,153 lbs (Regular Cab, Gas V8, DRW, 2WD)
• GVWR (Gross Vehicle Weight Rating): Up to 13,025 lbs (DRW configurations)
• GCWR (Gross Combined Weight Rating): Up to 31,300 lbs (Duramax diesel configurations)
• Curb Weight: 5,841 lbs to 7,750+ lbs (depending on cab, engine, and SRW/DRW)
• Hitch Class: Class V (2.5-inch receiver, often includes a 2-inch adapter sleeve)

Tow ratings by engine & trim

The 2019 Silverado 3500HD is offered with two primary engines: the standard 6.0L Vortec V8 gas engine and the legendary 6.6L Duramax V8 Turbo-Diesel (L5P). Ratings below represent maximums for their respective categories. Note: Actual ratings for your specific truck will vary. Always verify by checking the tire and loading information sticker on your driver-side door jamb.

Tow package contents

To achieve these massive numbers, Chevrolet equips the 2019 Silverado 3500HD with serious towing hardware. The standard Trailering Equipment Package (Z82) and heavy-duty components include:

• Heavy-Duty Cooling: High-capacity radiator and transmission oil cooler to prevent overheating on steep grades.
• Integrated Trailer Brake Controller (ITBC): Seamlessly integrates with the truck's ABS to provide measured brake force signaling to electrically braked trailers.
• Trailer Sway Control & StabiliTrak: Uses sensors to detect trailer sway and applies truck/trailer brakes while reducing engine power to bring the rig back into line.
• Diesel Exhaust Brake (Duramax only): Uses engine compression to slow the truck on downhill descents, significantly reducing wear on the traditional brakes.
• Wiring Setup: 7-pin and 4-pin trailer wiring connectors.

5th-wheel & gooseneck

Because this is a 1-ton heavy-duty truck, fifth-wheel and gooseneck towing is where the 3500HD truly shines. Moving the hitch point directly over the rear axle dramatically increases towing stability and weight capacity.

• 6.0L Gas V8 Max 5th-Wheel/Gooseneck: Up to 14,300 lbs (DRW, 2WD).
• 6.6L Duramax V8 Max 5th-Wheel/Gooseneck: Up to 23,100 lbs (Regular Cab, DRW, 2WD). Most Crew Cab DRW models hover around the 22,700 lb mark. Chevrolet offered a Factory Fifth-Wheel/Gooseneck Prep Package for the 2019 model, which includes a bed-mounted 7-pin trailer wiring harness and under-bed frame reinforcement for drop-in hitch systems.

Weight distribution & WDH requirements

While the 2019 Silverado 3500HD features a robust Class V hitch receiver, conventional towing above certain limits generally requires a Weight Distribution Hitch (WDH).

• For standard ball-mount (conventional) towing without a WDH, trailer weights are typically limited by hitch tongue weight (usually around 1,500 lbs maximum dead weight).
• If pulling conventional trailers over 10,000 lbs, a weight distribution hitch is highly recommended (and often required by the hitch receiver's safety rating) to level the truck, return steering authority to the front axle, and prevent excessive rear-end sag.

Real-world towing tips for this vehicle

• Watch your payload: A massive 23,100 lb gooseneck trailer will drop roughly 3,400 to 4,600 lbs of pin weight on your truck. If you have a fully loaded Crew Cab 4WD with the heavier diesel engine, you might exceed your payload capacity before you hit the max tow capacity.
• Utilize Tow/Haul Mode: Always engage this mode when pulling heavy loads. It alters the Allison transmission's shift points, keeping the engine in its optimal power band and maximizing engine braking.
• Check your tires: Dual rear wheels require vigilant tire pressure checks. Use a dual-chuck gauge to ensure the inner tires are adequately inflated before every trip.

Common towing-related issues

The 2019 Silverado 3500HD is widely considered a highly reliable towing platform, particularly models equipped with the L5P Duramax engine and Allison 1000 6-speed transmission. However, watch out for:

• DEF/Emissions System Faults: On diesel models, the Diesel Exhaust Fluid (DEF) heater, Nox sensors, or DPF systems can occasionally trigger "Reduced Engine Power" modes if they fail or become clogged from excessive idling.
• Suspension wear: Heavy, frequent towing will accelerate wear on rear leaf springs, shackles, and shock absorbers.
• Transmission cooling lines: Though generally stout, high-mileage trucks can develop leaks at the transmission cooler line fittings.
