In-Depth 2021 Ford F-350 Super Duty Towing Review
The 2021 Ford F-350 Super Duty towing capacity reaches a massive 21,000 lbs in conventional trailer configuration, establishing a benchmark for heavy-duty commercial haulers, fifth-wheel RV towing, and industrial equipment transport. Power is generated by the legendary 6.7L Power Stroke V8 Turbo Diesel engine delivering an extraordinary 475 horsepower at 2,600 RPM and 1,050 lb-ft of torque at 1,600 RPM. Power transfer is managed by a heavy-duty TorqShift 10-speed automatic transmission with live-drive power take-off (PTO) capability and specialized Tow
Haul programming to optimize shift timing under heavy drag. Vehicle mass ratings detail a Gross Combination Weight Rating (GCWR) spanning 28,700 to 31,100 lbs, a Gross Vehicle Weight Rating (GVWR) between 11,300 and 14,000 lbs, an unladen curb weight range of 6,900 to 8,030 lbs, and a certified static tongue weight allowance of 2,100 lbs across single-rear-wheel and dual-rear-wheel configurations.
Worksite productivity is maximized by the F-350 Super Duty max payload rating of 7,850 lbs on dual-rear-wheel (DRW) models, supported by high-capacity rear axles, heavy-duty leaf springs, and 17-inch or 18-inch commercial grade wheels. Installing options that meet factory tow package specifications equips the vehicle with a high-capacity hitch receiver, 5th-wheel
gooseneck hitch prep package, integrated trailer brake controller, and Ultimate Trailer Tow Camera System with 360-degree coverage. Engine exhaust braking functionality utilizes variable-geometry turbocharging to retard vehicle speed on steep mountain grades, preserving service brakes under full trailer loads. Heavy-duty frame crossmembers and solid front and rear axles ensure structural rigidity on rough worksite roads. Towing dynamic stability software continuously regulates wheel braking. Examining these extreme powertrain and torque specs demonstrates why the F-350 Super Duty is an industry favorite for commercial operators requiring heavy pulling power.
