A four-point link for the suspension of a rigid axle which has four bearing seats. Two bearing seats can be articulated on the axle and two can be articulated on the vehicle frame. The link has a single-piece link body which is inscribed by the trapezoid formed by the bearing seats. The link body is formed of a fiber-composite arrangement that comprises at least one longitudinal fiber arrangement. The longitudinal fiber arrangement encases the bearing seat, at least along half circumference thereof and extends along at least a portion of the link body in order to optimize loading, reduce mass and increase its application. Torsional compliance makes it possible to use relatively small and/or hard rubber bearings for articulating the four-point link or the vehicle axle.
