2019 Ford® Super Duty® Chassis Cab Truck | Durability Features Engineered for the Extremes | Ford.com

DURABILITY OVER THE LONG HAUL.

The Ford Super Duty® is the toughest, hardest-working generation of Class 3-5 chassis cab we’ve ever built. We started by cutting body weight with high-strength, military-grade, aluminum alloy that’s lighter than steel yet incredibly strong. We then invested some of that weight savings where it really counts — in stronger axles, chassis and steering components. Plus, we built the fully boxed under-cab and C-channel aft-of-cab frame 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 steel yet immensely strong. And it’s also more dent- and ding-resistant and not subject to red 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. Torsional rigidity is eight times greater than in 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.

RUGGED AXLES, CHASSIS AND DRIVELINE COMPONENTS

The frame of today’s Ford Super Duty® is stronger than ever before. The axles, suspension, brakes, driveline and transfer case are also 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, LARGE BRAKES

The components of the four-wheel anti-lock brakes in today’s generation of F-450/F-550 models are larger than the previous generation, 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 a 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 real and simulated conditions. We also put prototype models in the hands of people like you. Our goal: Build a line of Class 3-5 trucks with extraordinary performance and capability.

ENGINEERED FOR THE EXTREMES

Super Duty® was tested at temperatures from -20 to 120 degrees. Powertrain tests replicated going up a six-degree grade over 500 miles. Super Duty was also subjected to four-post frame twists, gravel, dust, water, brine, mud baths and even intentionally tested with worn or broken parts. Such extreme conditions often went far beyond what you would likely encounter on your toughest of jobs.
