Chevy Suburban towing capacity
The 2025 Chevy Suburban towing capacity depends on the engine, drivetrain, and equipment. The numbers you see are based on certain assumptions about passengers, standard gear, and weight. This section will explain why the numbers on the sticker might not match what you can actually tow.
Maximum towing numbers explained
GM says the Chevy Suburban can tow up to 8,200 lbs with a 5.3L V8 L84 engine and 2WD. This is 100 lbs less than the 2024 maximum. Diesel models with a 3.0L LZ0 Duramax engine can tow up to 8,100 lbs in certain 2WD builds.
The max trailer weight is calculated by subtracting the vehicle’s curb weight from its GCWR. Payload, passengers, and accessories also affect how much you can tow. The Trailering Information Label on the driver door and the owner’s manual will give you the exact rating for your vehicle.
How equipment and options change ratings?
Adding certain options can increase or decrease the Chevy Suburban’s towing capacity. For example, the Max Trailering Package (NHT) boosts the 5.3L 2WD rating to 8,200 lbs. But, extra passengers, roof racks, or heavy hitches can reduce the trailer weight because they use up payload.
Axle ratios are the same across the 2025 models, with a 3.23 final drive. So, the engine and drivetrain (2WD or 4WD) are what mainly affect the ratings. GM’s Trailering Guide notes that ratings assume a driver, front passenger, and required trailer equipment. Real-world towing capacity can be lower if these assumptions change.

Towing capability by drivetrain and package
The Suburban’s tow ratings vary based on drivetrain and optional equipment. It’s important to weigh drivetrain options and packages to meet towing needs. Below, we outline practical limits and what the Max Trailering Package offers.
2WD configurations and towing limits
Two-wheel-drive Suburbans usually have the highest tow ratings. This is because they have less weight and fewer drivetrain losses. For instance, a 5.3L 2WD can tow up to 8,200 lbs with the right setup.
The 3.0L Duramax 2WD also reaches around 8,100 lbs. Opting for 2WD is best when towing on paved roads and light off-road use. Always check the Trailering Label for exact numbers based on your VIN.
4WD configurations and towing limits
Four-wheel drive lowers tow ratings slightly. The added hardware increases curb weight and affects cooling and geartrain loading. A 5.3L 4WD might tow about 7,500 lbs in base form.
Some 4WD models with the Max Trailering Package can tow up to 8,000 lbs. The 3.0L diesel 4WD typically tows around 7,800 lbs. It offers strong torque for towing at lower speeds, but has slightly less capability than 2WD.
Max Trailering Package contents and benefits
The Max Trailering Package (RPO NHT) unlocks many top towing numbers. It includes a high-capacity radiator and an upgraded cooling fan for heavy loads. These features help avoid thermal derating during long towing sessions.
The package also adds an integrated trailer brake controller. It enables enhanced in-vehicle trailering features. Tow-focused aids like Hitch View and Hill Descent Control with Trailering are included.
Specifying NHT and choosing the right axle ratio and cooling system changes the maximum trailer weight. Always check the Trailering Information Label and owner’s manual for your exact configuration’s towing options and max towing capacity.
Payload, GCWR and weight ratings that affect towing performance
This section talks about how weight ratings impact towing with the 2025 Suburban. Knowing the chevy suburban towing specs and payload numbers is key. It helps drivers choose the right trailer size. Small mistakes in weight can lead to big safety issues.
Manufacturer payload examples show how different trims and engines affect capacity. Typical 2025 figures include:
| Engine / Drivetrain | Example Max Payload (approx.) |

| 3.0L Duramax Diesel, 2WD | 1,625 lbs |
| 3.0L Duramax Diesel, 4WD | 1,539 lbs |
Gross Combination Weight Rating, or GCWR, is the total weight limit for the vehicle and trailer. GM lists GCWR on the Trailering Information Label and in the Owner’s Manual. Always use GCWR as the maximum weight when planning a tow.
Start by weighing the loaded Suburban and trailer separately. Subtract the Suburban’s curb weight from GCWR to find the max trailer weight. Remember, GCWR, GVWR, and axle ratings are the legal and safe limits.
Tongue weight is key for stability. Aim for 10–15% of the trailer’s weight for conventional trailers. For gooseneck or fifth-wheel trailers, target 15–25%. When towing at or near the max trailer weight, the tongue load should be about 10% for conventional and 15% for gooseneck/fifth-wheel.
Proper weight distribution reduces sway and keeps steering stable. Place 60% of cargo in the front half of a conventional trailer. Keep side-to-side loads equal. Center trailer axles under the load and secure items to prevent shifting during braking and cornering.
Good practice checklist:
- Confirm the Suburban’s payload and axle ratings for the selected trim.
- Weigh the fully loaded tow vehicle and trailer before departure.
- Keep tongue weight within recommended percentages.
- Never exceed GCWR, GVWR or axle limits when adding passengers, fuel and gear.
Accurate attention to chevy suburban payload figures and GCWR ensures safe towing. Small planning steps lead to big safety benefits on the road.

Together, these features reduce driver workload and increase precision when towing in tight or challenging conditions.
Recommended hitches, wiring, and trailer brakes for safe towing
The right tools make towing easier and safer. This guide covers hitches, wiring, brakes, sway control, and weight distribution. It’s for those seeking clear towing advice and practical options for the Chevy Suburban.
Choosing the right hitch type for your trailer
Match hitch class and ball size to trailer weight and coupler. For light to medium trailers, a Class III or IV hitch is common. Make sure the ball diameter matches the coupler size and the ball rating is higher than the trailer’s weight.
Use a weight-distributing hitch with spring bars if recommended. This setup shifts weight to improve steering and braking on long trips.
Gooseneck or fifth-wheel hitches are for specific trailers and installations. SUV owners should check fitment and attachment points before assuming compatibility.
Wiring harness and trailer brake requirements
The 2025 Suburban has a 7-pin wiring harness for lights, brakes, and backup circuits. Use the factory connector for a secure, weather-resistant connection.
Trailer brakes are needed for weights over 2,000 pounds. Electric or hydraulic brakes are required by many states and GM. Electric brakes use a controller or the integrated brake controller in the Max Trailering Package.
Follow the controller and brake manufacturer’s instructions when installing an aftermarket controller. Test the system at low speed before hitting the highway. Regularly check wiring for damage and ensure solid grounding.
Sway control and weight distribution best practices
Aim for 10–15% tongue weight on conventional trailers. Too little tongue weight increases sway risk. For heavy loads, use a weight-distributing hitch and sway-control device.
Always cross safety chains beneath the trailer tongue. This creates a cradle to catch the tongue if it separates. Attach chains to frame points, not the bumper or cargo area.
Inspect hitch bolts, mounting brackets, and the coupler before each trip. Verify the hitch is mounted to the vehicle frame or approved points only. Regular inspection follows safety best practices and keeps towing reliable.
Trailering safety, loading tips, and legal considerations
Trailering needs careful planning and following state rules. Owners who follow safety tips have better control on long trips. Here’s a checklist for technicians and drivers before they leave.
Pre-trip safety checklist
Make sure the hitch is fully seated and the coupler latch is locked. Use safety chains in an X pattern for conventional trailers. Also, connect the breakaway cable.
Check tire pressure and tread on both the Suburban and trailer. Look for cuts, bulges, and proper valve caps. If your vehicle has tire monitoring, check that it shows all positions.
Test lights, turn signals, and trailer brakes. Start the truck and check the brakes. Adjust the gain until braking feels smooth. Also, check rear camera views and the Trailering App.
Check coolant level and oil condition when towing heavy loads. Consider the Max Trailering Package for extra cooling and towing endurance.
Load positioning and cargo securement
Aim for 10–15% tongue weight on conventional trailers. Place roughly 60% of cargo over the front half of the trailer. This keeps the trailer stable and reduces sway.
Distribute weight evenly side-to-side. An off-center load causes pull and increases sway risk. Use tie-down points rated for the cargo weight and cross-strap bulky items.
Choose high-quality ratchet straps, chains, and anchor fittings. Inspect fasteners, swivel hooks, and ratchet teeth before departure. Tighten straps after a short drive and recheck at stops.
State and federal regulations to be aware of
Trailer brake laws differ by state. Chevrolet recommends trailer brakes for trailers over 2,000 pounds. Check local rules before hauling to avoid fines and unsafe setups.
Observe GVWR, GCWR, and axle ratings on the vehicle certification label. Overloading is illegal and hazardous. Weigh the fully loaded vehicle and trailer at a public scale when in doubt.
Commercial or oversized loads may need permits, escorts, or route restrictions. Use Trailer Navigation to plan compliant paths. Avoid weight-restricted bridges or steep grades that exceed the tow rating.
Safe trailering combines good gear, careful loading, and following safety tips and rules. Regular practice of these checks keeps drivers and cargo safer on every trip.
Real-world towing performance and driving tips
The Chevrolet Suburban acts differently when towing a trailer. It accelerates slower and stops farther. Understanding how it handles makes driving safer and more reliable.
Braking, acceleration and handling with a trailer
Use the trailer brake controller to apply brakes smoothly. This reduces wear on the Suburban’s brakes. Adjust the controller for smooth trailer brake engagement.
Acceleration is slower, mainly with heavy loads. The turbo-diesel 3.0L Duramax is great for starting off. The 6.2L V8 is better for passing.
Drive at moderate speeds and leave more space behind you. Signal early for lane changes. Use small steering inputs to avoid trailer sway.
Highway and steep-grade driving tips
Use Tow/Haul mode for long trips. Downshift early on long descents to avoid brake overheating. Use Hill Descent Control for steady speed.
Watch transmission temperatures on steep grades. Plan rest stops for cooling. The Max Trailering Package helps with cooling.
Choose routes with fewer steep, narrow descents. Build speed before passing on hills. Diesel engines keep torque better, while V8s accelerate faster once revs increase.
Fuel economy expectations while towing
Towing greatly reduces fuel efficiency. Drag and trailer weight cut MPG. Expect a big drop in real-world fuel economy.
Diesel engines often have better fuel economy under load. Actual economy depends on many factors. Plan for shorter trips and use tire pressures for towing.
Practical tips: check cooling, brakes, hitch, and trailer lights before towing. Practice backing and turns in a safe area. Use Trailer Navigation for route planning.
