Ford F-250: FULLY BOXED HIGH-STRENGTH STEEL FRAME
The fully boxed frame, built of over 95 percent high-strength steel with up to 10 crossmembers, is 24 times stiffer than the previous design. The frame is designed to minimize flexing and twisting while maximizing strength and torsional rigidity - and serves as the foundation for Super Duty achieving the highest payload and tow ratings in its class.

Ford F-350: WHAT TOUGHNESS MEANS IN BIG PICKUPS
Today's Ford Super Duty® is the toughest heavy-duty pickup we've ever built. We started by cutting body weight with high-strength, military-grade, aluminum alloy. We then invested some of that weight savings where it really counts - in stronger axles, beefier steering and chassis components, and a fully boxed frame built of over 95 percent high-strength steel. The result is a Super Duty that boasts class-leading payload and towing.
