Coming from the F-450 series, the Super Duty boasts some of the company's most powerful engine blocks. You'll get more than 900 lb-ft of peak torque at small RPMs from the Power Stroke engine block. Designed to use traditional diesel or B20 fuel, the six-cylinder engine also has great off-road capabilities. For example, the exhaust brake system stabilizes this Ford truck on downward grades. You'll also enjoy great hill-climbing leverage thanks to the TorqShift auto transmission system that yields up to six gear settings. The patented gearbox has some settings that help with towing and hauling.
