The 2017 Super Duty is the toughest and most capable Ford full-size pickup truck ever. All-new high-strength, military-grade, aluminum alloy slashed the weight of the body. Some of that weight savings was then reinvested where it counts the most in a work truck, in an all-new fully boxed frame built of over 95 percent high-strength steel, stronger axles, beefier steering and chassis components. The result is a pickup that's stronger than ever before, yet up to 350 lbs lighter. The 385hp 6.2L gas V8 is more heavy work-capable than ever delivering 430 pound-ft. of torque. The available 440hp 6.7L Power Stroke Turbo Diesel V8 comes through with best-in-class horsepower and torque delivering 925 pound-ft. of torque. The F-450 has a 21,000 max loaded trailer weight rating for conventional towing, 32,500 pounds for fifth wheel gooseneck towing max loaded trailer weight rating and up to 41,800 pounds gross combination weight rating. Those figures all depend on engine type, cab size, and drivetrain.
