In this work the development of a SHSS (Super High Strength Steel) tube with improved cold formability is presented and applied to a new manufacturing route for the production of stabilizer bars of light trucks. The paper starts with an experimental outdoor analysis in order to measure the so called load spectra. In this way, the loading conditions at which the stabilizer bar is subjected are identified, both in terms of fatigue conditions and number of cycles as well as overloads. After that and by using finite element analysis, the material targets in terms of ultimate tensile strength, fatigue properties and yield strength are defined. On this basis, an innovative manufacturing process, more competitive in terms of total cost, is proposed and briefly described. The paper ends with the experimental validation of the real component. Results show very good outputs, since the component successfully pass the qualification tests as well as additional tests specially designed in order to consider the response of the component to actual overloads.
