Three different engines are offered on the Super Duty trucks, too. A 5.4L V8 making 300 horsepower and 365 lb-ft of torque is standard, and for heavier duty there's either the 6.8L V10, with 362 horsepower and 457 lb-ft, or the 6.0L "Power Stroke" turbo-diesel V8, making 325 horsepower and 570 lb-ft. Each engine is available with either a six-speed manual or five-speed automatic transmission.
With either the diesel or V10, the Super Duty can tow up to 15,000 pounds using a conventional trailer hitch. The F-350 is available with a dual-rear-wheel (DRW, or "dually") setup that allows better stability for towing the heaviest trailers, and there's also an available TowCommand system, which includes a unique trailer-braking strategy that works in conjunction with the Super Duty's anti-lock braking system when it detects poor traction. The Super Duty has a fully boxed front frame section, and Ford claims to use the thickest-gauge steel of any pickup in its frame.
The Super Duty models have a more upright appearance compared with the standard-duty F-150, especially at the front. The front end is more squared-off, with an upright grille that borrows some elements of its appearance from big rigs.
Both two- and four-wheel-drive models come in XL, XLT, and Lariat trims, with the Lariat including a luxurious premium leather interior, automatic climate control, and many comfort and convenience features.
There are also several special appearance packages. The King Ranch brings unique wheels, Arizona Beige trim, and an interior with Castano Brown King Ranch leather plus other additional luxury and interior appearance items. The Lariat Highline Edition adds chrome trim throughout, including on the billet-style grille, tubular step bars, tow hooks, exhaust tip, and instrument trim. Captain's chairs and black leather upholstery bring the interior a different look. There's also a Lariat Outlaw Package, which comes with a monotone black exterior with red tape stripe; inside the black theme continues with black and red leather-trimmed captain's chairs.
