2023 Chevrolet Suburban Towing Capacity & Payload Guide

The 2023 Chevrolet Suburban can tow a maximum of 8,300 pounds when properly equipped with the 5.3L V8 engine, rear-wheel drive (2WD), and the Max Trailering Package. As one of the largest and most capable traditional body-on-frame SUVs on the market, the Suburban is heavily relied upon by families who need massive passenger space without sacrificing the ability to haul heavy boats, travel trailers, or toy haulers.

However, because the Suburban is offered with three different engines, two drivetrains (2WD and 4WD), and various trims, your specific towing capabilities will vary. Always check the door-jamb sticker on your exact vehicle before hooking up a trailer.

Quick answer

• Max Tow Capacity: Up to 8,300 lbs (5.3L V8, 2WD, Max Trailering Pkg)
• Max Payload Capacity: Up to 1,759 lbs (5.3L V8, 2WD)
• GVWR (Gross Vehicle Weight Rating): 7,500 to 7,700 lbs (depending on engine and drivetrain)
• GCWR (Gross Combined Weight Rating): 14,000 to 14,500 lbs (depending on equipment)
• Curb Weight: 5,616 to 6,144 lbs
• Hitch Class: Standard Class IV receiver with 2-inch receiver tube.

Tow ratings by engine & trim

The 2023 Suburban conforms to SAE J2807 towing standards, meaning these ratings have been rigorously tested on real-world grades and in high-heat environments. Note that achieving the absolute maximum figures requires the Max Trailering Package (NHT). Without it, most Suburban models are capped at around 7,400 to 7,900 pounds.

Note: The 3.0L Duramax Diesel achieves its maximum towing capacity natively and does not see a towing capacity increase from the Max Trailering Package, though the package adds other useful towing features.

Tow package contents

If you plan to tow anything near the limit, finding a Suburban equipped with the Max Trailering Package (RPO Code NHT) is highly recommended. For the 2023 model, this package typically includes:

• Integrated Trailer Brake Controller: Allows you to adjust and apply the trailer's brakes directly from the dashboard.
• Advanced Trailering System: Includes an in-vehicle trailering app with customized trailer profiles, pre-departure checklists, and trailer tire pressure/temperature monitoring.
• Hitch Guidance with Hitch View: Uses the rear camera to provide a top-down view of the hitch for easy, solo hookups.
• Enhanced Cooling Radiator: Extra thermal capacity to keep engine and transmission temperatures in check on long, steep grades. (Included mostly with V8 models).
• Smart Trailer Integration Indicator: Monitors trailer connection.
• Standard Equipment: All models come with a standard 2-inch receiver, a 7-pin wiring harness, and standard Trailer Sway Control baked into the StabiliTrak system.

5th-wheel & gooseneck

Because the 2023 Chevrolet Suburban is a fully enclosed SUV with an independent rear suspension, it is not compatible with 5th-wheel or gooseneck hitches. These setups are strictly reserved for heavy-duty pickup trucks (like the Silverado 2500HD and 3500HD). All towing with the Suburban must be done via a conventional bumper-pull setup.

Weight distribution & WDH requirements

For conventional towing, General Motors strongly recommends the use of a Weight Distribution Hitch (WDH) and sway control when towing a trailer heavier than 5,000 pounds.

Given the Suburban's independent rear suspension, a heavy tongue weight can cause the rear end to sag, leading to reduced steering authority and compromised braking dynamics. A properly adjusted WDH will transfer a portion of that tongue weight back to the front axle of the Suburban and the axles of the trailer, keeping the vehicle level. Always target a tongue weight between 10% and 15% of your loaded trailer weight.

Real-world towing tips for this vehicle

• Mind your Payload: The Suburban is massive, meaning it is often filled with 7 or 8 passengers and their luggage. Remember that every pound of passengers and cargo inside the SUV directly subtracts from your available payload. You might run out of payload capacity (which handles the trailer's tongue weight) long before you reach the 8,300-pound max tow limit.
• Tow/Haul Mode: Always engage Tow/Haul mode when pulling a heavy load. This alters the 10-speed automatic transmission’s shift points, holding gears longer to prevent "hunting" on hills and providing engine braking when going downhill.
• Air Suspension Advantages: If your Suburban is equipped with the available Air Ride Adaptive Suspension, it will automatically load-level the rear end. This is fantastic for towing, but you still need a WDH for trailers over 5,000 lbs. Be sure to follow GM's specific procedure for setting up a WDH with the air suspension (usually requiring the suspension to be in a specific mode during setup).

Common towing-related issues

• Lifter Issues under Heavy Load: The 5.3L and 6.2L V8 engines feature Dynamic Fuel Management (DFM). While mostly reliable, extended periods of heavy engine load and heat can exacerbate known GM lifter issues. Frequent oil changes are highly recommended if you tow often.
• Transmission Heat: While the 10-speed transmission is robust, towing near the GCWR limit in summer heat can raise fluid temperatures. Monitor your transmission temp via the driver information center.
• Brake Wear: The Suburban is a heavy vehicle on its own (nearly 6,000 lbs). Relying purely on the SUV’s brakes to stop an 8,000-pound trailer is a recipe for warped rotors. Always ensure your integrated brake controller is properly calibrated for your trailer's weight.
