MEANING OF TOUGH REDEFINED. FOREVER.
Yesterday’s meaning of tough — heavy strength — has changed forever with high-strength, military-grade, aluminum alloy replacing conventional steel in the cab/bed of the stronger yet lighter Ford F-150. Not aluminum in the household sense, but heat-treated and hardened aluminum alloy — the same high-grade 6000-series used in big military and industrial applications. This bold concept took shape with advanced computer-aided design technology, followed by F-150 prototypes subjected to over 10 million cumulative miles of torturous testing on Ford proving grounds and in real world jobs.
