2017 GMC Yukon Towing Capacity & Payload

The 2017 GMC Yukon can tow between 6,300 and 8,500 pounds, depending on the configuration.

Quick answer

• Max Towing Capacity: 8,500 lbs
• Max Payload Capacity: 1,760 lbs
• GVWR: 7,300 lbs
• GCWR: 14,000 lbs
• Curb Weight: 5,340 – 5,690 lbs
• Hitch Class: Class III or Class IV (varies by configuration, typically 500-850 lbs tongue weight without WDH, 750-1,275 lbs with WDH)

Tow ratings by engine & trim

The 2017 GMC Yukon's towing capacity varies significantly based on the engine, drivetrain, and specific trim or package. Generally, models equipped with the 5.3L V8 engine and 2WD offer the highest towing capacities.

Note: These figures are based on manufacturer specifications. Always refer to your vehicle's door jamb sticker for the most accurate and specific towing and payload capacities.

Tow package contents

For the 2017 GMC Yukon, the available heavy-duty trailering package (often standard on specific trims or optional) includes several key components designed to enhance towing capability and safety:

• Integrated Trailer Brake Controller: Allows for precise control of electric trailer brakes directly from the Yukon's cabin.
• Automatic Leveling Suspension: Helps maintain a level ride height when towing heavy loads, improving stability and handling.
• Heavy-Duty Transmission Cooler: Prevents the transmission from overheating during strenuous towing, extending its lifespan.
• Trailer Sway Control: An electronic stability control system that detects and counteracts trailer sway, helping to maintain control of the vehicle and trailer.
• 7-pin Wiring Harness: Provides power, ground, and controls for trailer lights, electric brakes, and auxiliary functions.
• 2-inch Receiver Hitch: Class III or Class IV rated, depending on the specific Yukon configuration.

5th-wheel & gooseneck

The 2017 GMC Yukon is not designed for 5th-wheel or gooseneck towing. These types of hitches are typically reserved for heavy-duty pickup trucks and require a much stronger frame and different bed structure than what the Yukon offers.

Weight distribution & WDH requirements

For trailers exceeding 5,000 pounds, it is strongly recommended, and often required by GMC, to use a Weight Distributing Hitch (WDH) system with the 2017 Yukon. A WDH helps to distribute the tongue weight of the trailer more evenly across all axles of the tow vehicle and trailer. This helps to:

• Prevent excessive sag at the rear of the Yukon.
• Improve steering and braking control.
• Increase stability and reduce sway.
• Allow for higher tongue weight capacities (typically increasing tongue weight capacity by several hundred pounds).

Always consult your owner's manual for specific WDH requirements and maximum tongue weight capacities with and without a WDH.

Real-world towing tips for this vehicle

• Monitor Your Weights: Never exceed your Yukon's maximum towing capacity, payload capacity, GVWR, or GCWR. Weigh your loaded vehicle and trailer at a certified weigh station.
• Proper Loading: Distribute the trailer's load to achieve approximately 10-15% of the total trailer weight as tongue weight. Too little or too much tongue weight can lead to instability.
• Tire Pressure: Ensure both the Yukon's and the trailer's tires are inflated to the manufacturer's recommended pressures for towing.
• Pre-Trip Inspection: Before each tow, check all lights, brakes, tire pressures, and hitch connections.
• Drive Conservatively: Allow for increased braking distances, accelerate gradually, and avoid sudden maneuvers. Use a lower gear to maintain control on descents and to reduce strain on the transmission.
• Check Fluids Regularly: Especially when towing, regularly check your engine oil, transmission fluid, and coolant levels.

Common towing-related issues

• Transmission Overheating: Heavy towing puts extra strain on the transmission. Ensure your transmission cooler is in good working order, and consider regular transmission fluid changes.
• Brake Wear: The added weight of a trailer significantly increases braking demands. Monitor brake pad and rotor wear, and ensure your trailer brakes are properly adjusted and functioning.
• Suspension Sag: Without proper weight distribution, heavy tongue weight can cause the rear of the Yukon to sag, impacting handling and headlight aim. A WDH or air helper springs can alleviate this.
• Tire Wear: Uneven tire wear on the tow vehicle can be a sign of improper loading or alignment issues exacerbated by towing.
• Electrical Problems: Trailer light or brake issues can often be traced back to faulty wiring, corrosion in the connectors, or issues with the trailer brake controller.
