GMC SUVs are built with power, performance, and capability in mind. With strong engines, sturdy frames, and advanced trailering technology, GMC SUVs can confidently haul boats, campers, ATVs, and more down the open road.
But to get the most out of your GMC SUV’s towing abilities, you need to understand the factors that determine towing capacity. In this complete guide, we’ll cover everything you need to know about maximizing GMC SUV towing capacity.
What Determines Towing Capacity?
Towing capacity refers to the maximum weight a vehicle can safely tow. This number depends on several key factors:
-
Engine power – More horsepower and torque allow an SUV to pull heavier loads. GMC SUVs have strong V6 and V8 engines ranging from 310 to 420 horsepower.
-
Transmission – Automatic transmissions designed for towing have extra gears and cooling systems. GMC SUVs have 6-, 8-, and 10-speed transmissions.
-
Chassis and suspension – A rigid frame, heavy-duty components, and self-leveling suspension enhance stability under load. GMC SUVs have fully-boxed frames and trailering packages.
-
Braking system – Larger brakes with integrated trailer brake controllers provide confident stopping power. GMC SUVs have 4-wheel antilock disc brakes.
-
Cooling system – Upgraded radiators, fans, and transmission coolers prevent overheating when towing. GMC SUVs have specially designed cooling systems.
-
Weight ratings – The vehicle’s Gross Combination Weight Rating (GCWR) limits the combined weight of the SUV and trailer.
GMC SUV Towing Capacity Chart
| GMC SUV Model | Max Towing Capacity |
|---|---|
| 2023 GMC Yukon 2WD | 8,400 lbs |
| 2023 GMC Yukon 4WD | 8,200 lbs |
| 2023 GMC Yukon XL 2WD | 8,000 lbs |
| 2023 GMC Yukon XL 4WD | 7,900 lbs |
| 2023 GMC Acadia FWD | 4,000 lbs |
| 2023 GMC Acadia AWD | 3,500 lbs |
| 2023 GMC Terrain FWD | 1,500 lbs |
| 2023 GMC Terrain AWD | 3,500 lbs |
Towing capacity can vary slightly by trim and engine options. Refer to owners manual for exact tow rating.
As you can see, the larger GMC Yukon and Yukon XL SUVs offer the greatest towing capabilities, over 8,000 pounds with certain configurations. The midsize Acadia can manage between 3,500-4,000 pounds depending on drivetrain. The compact Terrain has the lowest capacity at 1,500-3,500 pounds.
Tips for Maximizing GMC SUV Towing
To get the most out of your GMC SUV’s tow rating, keep these tips in mind:
Choose the right hitch – Use a hitch designed for the SUV’s max tow weight and passenger capacity. The hitch type (receiver, 5th wheel, gooseneck) depends on the trailer.
Use a weight distribution system – For heavier loads, a weight distribution hitch applies leverage to distribute weight and improve handling.
Check tongue weight – The downward force of the trailer tongue on the hitch should be 10-15% of total loaded trailer weight.
Load trailer properly – Distribute cargo evenly from front to back and side to side. Heavy items go over the axle area.
Weigh the load – Use public scales to confirm the SUV, passengers, cargo, and loaded trailer are within all weight limits.
Use tow/haul mode – Engages engine braking, optimized transmission shift points, and trailer brake control.
Adjust driving habits – Accelerate, brake, and steer smoothly. Allow extra distance for passing and stopping.
Watch transmission temp – Especially when climbing hills, monitor temperature gauge to avoid overheating.
Check oil and fluids – Towing puts more stress on the drivetrain, so inspect oil, transmission fluid, coolant, brake fluid regularly.
Inflate tires – Verify tires (including spare and trailer) are inflated to maximum recommended pressures.
Verify electrical connections – Check all trailer light and brake controller connections are working properly.
Use towing aids – Consider extended mirrors, backup cameras, and apps to monitor trailer status while driving.
GMC SUV Towing Features
GMC SUVs come standard or available with a full suite of trailering technologies:
-
Trailer brake controller – Integrated controller applies the trailer brakes in sync with SUV brakes.
-
Tow/Haul mode – Calibrates transmission shift points and engine power output when towing.
-
Hitch Guidance – Centerline overlay on rear camera display helps line up hitch.
-
Jackknife alert – Warns if trailer is swaying dangerously and reduces engine power.
-
Hill Start Assist – Prevents rollback when starting on an incline.
-
Auto Grade Braking – Utilizes engine compression to help maintain speed downhill.
-
Digital inclinometer – Displays side-to-side and front-to-back tilt to help with weight distribution.
-
Trailering app – Provides trailer light diagnostics, tire pressure/temp monitoring, and trip planning.
Towing Capacity FAQs
What reduces towing capacity? Additional cargo, passengers, and aftermarket accessories all eat into available payload capacity, which directly affects tow ratings. Removing heavy components like the spare tire can help increase capacity.
How is towing capacity calculated? Automakers calculate tow ratings by testing vehicles while gradually increasing trailer loads until maximum safe limits are determined. Many factors are considered under controlled conditions.
Why does 4WD lower capacity? The additional weight and friction of 4WD systems increase stress on drivetrain components, necessitating lower ratings. Disconnecting the front driveshaft can allow 2WD-equivalent capacity.
Can I exceed the tow rating? Exceeding any weight rating risks damage, increased wear, loss of control, or accidents. Tow capacity is the maximum safe limit set by the manufacturer after extensive testing.
Do different hitches change capacity? The SUV’s max tow rating assumes use of a standard receiver or fifth-wheel hitch. Weight distribution or other special hitches themselves do not increase capacity.
