2021 GMC Yukon AT4 Towing Capacity
The Yukon AT4 pairs rugged off-road capability with excellent towing power. When properly equipped, max towing specs are:
- Max Conventional Towing – 7,700 lbs
This allows the midsize Yukon AT4 SUV to pull a variety of recreational, cargo and boat trailers with confidence. Towing capacity is consistent across 2WD and 4WD configurations. As with the Sierra, equipping the available 6.2L V8 engine and trailering package helps achieve the max rating.
2021 GMC Acadia AT4 Towing Capacity
The new Acadia AT4 provides a balance of trail-ready styling and towing versatility. When properly equipped, max towing is rated at:
- Max Conventional Towing – 4,000 lbs
This allows the Acadia AT4 to tow small-to-medium sized trailers including:
- Small pop-up campers
- Lightweight boats like bass boats and skiffs
- Single-axle utility trailers
Towing capacity remains consistent across front-wheel or all-wheel drive AT4 models. As with all Acadia trims, the trailering package is required to reach the max 4,000 lb tow rating.
2021 Canyon AT4 Towing Capacity
While not yet available, a future Canyon AT4 model is expected with similar off-road enhancements as other AT4 models. Max towing capacity will depend on cab, bed, drivetrain and engine:
- 2.5L 4-Cylinder – 3,500 lbs capacity
- 3.6L V6 Gas – 7,000 lbs capacity
- 2.8L Diesel – 7,700 lbs capacity
When equipped with the trailering package, the Canyon AT4 will offer excellent midsize truck towing versatility.
AT4 Towing Features and Equipment
In addition to unique exterior styling, off-road suspension and aggressive all-terrain tires, AT4 models include standard and available trailering features:
- Standard trailering hitch receiver
- Available integrated trailer brake controller
- Rear vision camera with hitch view
- Trailer sway control
- Hill descent control
- Auto locking rear differential on truck models

While max towing requires GM’s Max Trailering Package, the AT4 line is well-equipped for moderate towing needs right from the factory. Careful attention must still be paid to GCWR, payload capacity and proper weight distribution when towing near max ratings. With the right setup, the 2021 GMC AT4 lineup provides reliable towing power for outdoor adventures and family trips.
