A length adjustable steering column module for a motor vehicle has a support beam attachable to the motor vehicle. The module includes a steering column rotatable about a longitudinal axis, and has an upper and a lower steering tube. The upper steering tube is displaceable in the direction of the longitudinal axis and is non-rotatably connected to the lower steering tube. An adjusting device adjusts the distance of the upper steering tube from the lower steering tube. A jacket tube has an annular area, a crash member, and an upper and a lower end portion, the upper end portion grasps around the upper steering tube, and axially fixes and rotatably supports the upper steering tube. A central bearing is disposed between the annular area and the upper steering tube. The crash member, located between the central bearing and the lower end portion, shortens in the event of an accident.
