Redesigned from the ground up on an all-new full-size truck platform, the 2021 GMC Yukon towing capacity reaches an extraordinary peak rating between 8100 and 8400 lbs when properly outfitted with factory tow package specifications. Under the hood, buyers can choose between three distinct engine configurations supplying exceptional powertrain and torque specs: a standard 5.3L V8 EcoTec3 producing 355 horsepower and 383 lb-ft of torque, a high-output 6.2L V8 EcoTec3 generating 420 horsepower at 5600 RPM and 460 lb-ft of torque, or an ultra-efficient 3.0L Duramax inline-six turbo-diesel delivering 277 horsepower and a commanding 460 lb-ft of low-end torque at just 1500 RPM. All engine options pair with a smooth 10-speed automatic transmission featuring Tow
Haul mode, grade braking, and shift-on-the-fly drive controls. Across all trims, structural ratings showcase a Gross Combination Weight Rating (GCWR) of 14000 to 14500 lbs, a Gross Vehicle Weight Rating (GVWR) of 7400 to 7600 lbs, and a solid Curb Weight ranging from 5356 to 5827 lbs. Though the Yukon max payload rating varies by cabin equipment and seating package, the chassis excels at transporting heavy boats, horse trailers, travel trailers, and heavy construction equipment.
Constructed with a fully boxed high-strength steel frame, the 2021 Yukon introduces an independent rear suspension that dramatically enhances ride isolation, rear passenger legroom, cargo volume, and directional stability while towing heavy loads on open highways. Engineered for maximum towing confidence, available trailering technologies include an integrated trailer brake controller, Hitch Guidance with Hitch View camera alignment, and an In-Vehicle Trailering App with customized trailer profiles, checklist reminders, and tire pressure monitoring. Supported by maximum static tongue weight limits between 810 and 840 lbs, 18-inch to 22-inch aluminum wheels, and optional Air Ride Adaptive Suspension, the Yukon sets a benchmark for full-size luxury towing capability, heavy hauling resilience, and refined highway performance.
