A method for producing a torsional profile from a tubular hollow profile, the torsional profile being provided, over its entire length, with spaced-apart walls, is provided. The method includes placing the tubular hollow profile into a first deformation die, positioning the ends of the tubular hollow profile in the first deformation die by means of in each case one tapering first mandrel which extends into a torsional region, positioning the tubular hollow profile over its longitudinal extent in the first deformation die, deforming the tubular hollow profile over its longitudinal extent in the torsional region by means of a first punch, with a reduction in the tube cross-sectional area in the torsional region, and removing the first punch and the first mandrels.
