6. Specify Cab and Bed Configurations
Different cab styles (Regular, Double, Crew) and bed lengths affect your vehicle’s weight and distribution, which in turn impacts available towing capacity.
7. Include Towing Packages
Factory-installed towing packages can significantly enhance your Denali’s capabilities. The Max Trailering Package, for instance, includes enhanced cooling, revised suspension, and integrated trailer brake controllers.
After entering all your vehicle’s specifications, click “Calculate Towing Capacity” to get your personalized results, including a visual comparison with other configurations and important safety information.
Understanding Towing Capacity Calculations
Towing capacity isn’t a single number—it’s a carefully calculated value based on engineering principles and safety standards observed worldwide. Here’s what goes into the calculation:
Gross Vehicle Weight Rating (GVWR)
GVWR is the maximum total weight of your loaded vehicle—including passengers, cargo, and fuel—as specified by the manufacturer. This forms the foundation for all other capacity calculations.
Gross Combined Weight Rating (GCWR)
GCWR is the maximum total weight of your loaded vehicle plus your loaded trailer. This rating considers the vehicle’s engine, transmission, brakes, cooling system, and frame strength.
Payload Capacity
Payload is the maximum weight your vehicle can carry in passengers and cargo. When towing, tongue weight (typically 10-15% of trailer weight) counts against your payload capacity.
Tongue Weight and Hitch Considerations
Proper tongue weight is critical for safe towing. Too little tongue weight can cause trailer sway, while too much can overload the rear axle. The type of hitch (conventional, weight-distributing, or fifth-wheel) also affects capacity.
Our calculator considers all these factors according to SAE International standards (J2807) that manufacturers in the United States, Canada, Europe, and other global markets follow. This ensures consistent, comparable towing ratings across the industry.
Frequently Asked Questions
The maximum towing capacity varies by model and configuration. The GMC Sierra 3500HD Denali can tow up to 20,000 pounds when properly equipped, while the Yukon XL Denali can tow up to 8,400 pounds. Always check your specific vehicle’s capabilities using our calculator or consult your owner’s manual.
Towing capacity depends on multiple factors including engine size, transmission, drivetrain, axle ratio, cab configuration, and whether the vehicle has additional towing packages. Heavier-duty models like the 2500HD and 3500HD are built with reinforced frames, more powerful engines, and enhanced cooling systems to handle greater weights.
Payload capacity is the maximum weight your vehicle can carry, including passengers, cargo, and the tongue weight of your trailer. It’s directly subtracted from your towing capacity. Exceeding your payload capacity is dangerous and can cause vehicle instability, even if you’re within your towing limit.
While you can’t fundamentally increase the manufacturer’s rated capacity, you can optimize your vehicle’s towing capabilities by adding factory-approved towing packages, proper hitch equipment, and ensuring your vehicle is well-maintained. Never exceed the manufacturer’s stated limits as this can void warranties and create unsafe driving conditions.
You should recalculate whenever you modify your vehicle, change your trailer, or add/remove equipment that affects weight distribution. It’s also good practice to verify your towing capacity at the beginning of each towing season or before major trips, especially if you’re carrying different loads or passengers.
Global Towing Standards and Regulations
Towing regulations vary by country, but our calculator adheres to the strictest international standards to ensure safety wherever you travel:
United States and Canada
In North America, towing capacity is determined using the SAE J2807 standard, which includes specific testing procedures for acceleration, grade climbing, and handling. All major manufacturers including GMC follow this standard, ensuring consistent ratings across the industry.
European Union
The EU follows similar standards with additional emphasis on lighting requirements, brake systems, and trailer stability controls. Vehicles must meet EC whole vehicle type approval regulations.
Australia
Australian standards require robust tow bar certifications and consider extreme weather conditions in their calculations. Many Australian states also require independent brake controllers for trailers over certain weights.
Regardless of your location, our calculator provides conservative estimates that should meet or exceed local requirements when used with proper equipment and within the specified limits.

Safety Considerations When Towing
Knowing your towing capacity is just the beginning of safe towing practices. Always follow these important safety guidelines:
Proper Load Distribution
Distribute weight evenly in your trailer, with approximately 60% of the weight in the front half. This maintains proper tongue weight and prevents sway.
Regular Maintenance
When towing frequently, adhere to severe service maintenance schedules for your engine, transmission, brakes, and cooling system.
Speed Considerations
Reduce speed when towing, especially in adverse weather conditions, on steep grades, or when passing large vehicles that can create wind buffeting.
Braking Distances
Remember that stopping distances can double or triple when towing heavy loads. Leave extra space between you and other vehicles.
Practice Maneuvering
Before hitting busy roads, practice turning, backing up, and stopping in a safe, empty area to get comfortable with your vehicle’s handling characteristics when towing.
