2018 Ford Super Duty on a job site

DURABILITY FOR THE LONG HAUL.

The 2018 Ford Super Duty® is the toughest, hardest-working generation of Class 3-5 chassis cab we’ve ever built. The cab is made of high-strength, military-grade, aluminum alloy that’s lighter than steel yet incredibly strong. Some of that weight savings went into making the axles, chassis and steering components stronger. Plus, the fully boxed under-cab and C-channel aft-of-cab frame is built of 95 percent high-strength steel. That means hauling and towing capability you can depend on to deliver every workday.

HIGH-STRENGTH, ALUMINUM-ALLOY BODY

The Ford Super Duty® is the only Class 3-5 chassis cab with a high-strength, military-grade, aluminum-alloy body. It’s lighter than the previous generation steel yet immensely strong. And it’s also more dent- and ding-resistant and not subject to rust corrosion. Beneath this lighter body is a fully boxed under-cab frame and a C-channel aft-of-cab frame built of 95 percent high-strength steel.

TOUGH AND DURABLE HIGH-STRENGTH STEEL FRAME

Super Duty® Chassis Cab features a fully boxed under-cab and C-channel aft-of-cab frame made of 95 percent high-strength steel with up to 10 crossmembers (eight through-welded). Torsional rigidity is eight times greater than the previous generation. The C-channel frame easily accommodates a wide range of upfits from flat and dump beds to wrecker, service and delivery bodies.

AXLES, CHASSIS AND DRIVELINE COMPONENTS

The frame of today’s Ford Super Duty® is stronger than the previous generation’s. And so the axles, suspension, brakes, driveline and transfer case are larger and heftier for greater strength and capability. Super Duty chassis cabs are more than up to the task of taking on the toughest jobs in the most demanding industries.
Tough and hefty brakes with the largest rotors in their class

TOUGH, HEFTY BRAKES

The components of the 4-wheel anti-lock brakes in today’s generation of F-450/F-550 models are larger than before, with the largest rotors in their class* — and for two important reasons. You want them to provide the sure stopping power you expect when you’re out on the job hauling tons of equipment or cargo. And you want them to last, because having to replace brakes too often can be drag on your bottom line.

OVER 12 MILLION MILES OF TESTING

We committed this latest generation of the Super Duty to over 12 million miles of testing, under conditions simulated and real. We also put prototype models in the hands of people like you, working in some of the most demanding industries. Our goal: Build a line of Class 3-5 trucks with extraordinary performance and capability.
Engineered for the extremes of on the job punishment

ENGINEERED FOR EXTREMES

We evaluated the Super Duty® on computers and dynamometers in the lab, then tested it at the proving grounds and on public roads and highways at temperatures from -20 to 120 degrees Fahrenheit. We conducted thermal shocks that swung ambient temperature 250 degrees Fahrenheit in under two minutes, as well as powertrain tests that replicated going up a six-degree grade over 500 miles. We subjected Super Duty to four-post frame twists, gravel, dust, water, salt brine, mud baths and even intentionally tested with worn or broken parts. We’re talking here about extreme conditions that often went far beyond what you would likely encounter on your toughest of jobs.
