Abstract: An efficient method for producing spring strut forks for motor vehicles is presented. In each case two spring strut forks are produced from a metallic extruded profile as a starting product. The extruded profile has a central, middle main chamber and four longitudinal chambers which are arranged offset with respect to one another over the circumference of the main chamber.
