Ford says that its revised 2013 F-Series Super Duty's maximum conventional towing capacity is now rated at 18,500 lbs., a figure that surpasses its nearest competitor by 500 lbs.
Similarly, the F-Series Super Duty's Gross Vehicle Weight Rating - or GVWR - is now a class-leading 14,000 lbs. and the truck's maximum payload has increased by 100 lbs. to 7,260 lbs.
By comparison, properly-equipped versions of General Motors' two full-size heavy duty trucks, the Chevrolet Silverado 3500HD and the GMC Sierra 3500HD, are rated to tow up to 18,000 lbs. with a conventional trailer hitch. Ram's revised 2013 HD trucks have not been officially rated by the manufacturer.
Previously, the F-Series Super Duty was rated at a maximum of 17,000 lbs.
In addition, the F-Series Super Duty's brakes have been upgraded to provide better heat dissipation. The towing and hauling capacity ratings were upgraded without any changes to the truck's suspension.
Ford rates its trucks using its own internal numbers, not SAE standards.
