Abstract: A novel method and apparatus for forming stabilizer bars for engine driven land vehicles starting from tubular or rod steel stock material to provide predetermined shapes which are hardened by heat treating, forming and quenching into permanent forms. The method comprises of heating bar ends and forging in forging presses so that one of the eyed ends after heating to 1150.degree.-1240.degree. C. for forging and piercing is formed. The same series of heating, forging and piercing steps are carried out at the other end to thereby provide a new strengthened eyehole structure at each end. The bar is then heated and formed on a forming table. The heating is carried out at 870.degree.-910.degree. C. and the bending on the forming table is carried out. A drain aperture is pierced in the side of the tubular stock to drain the quenching oil which enters the tube during quenching after forming the stabilizer bar. The novel forming board is provided with twelve cylinders.
