Zusammenfassung:	A flexible trailing arm (1) for an air sprung wheel axle suspension of a vehicle is forged of spring steel. The trailing arm (1) has a front end portion (2) to be pivotally mounted to a chassis, an axle attachment portion (4) at a longitudinal distance from the front end portion (2), and a spring portion (3) extending between the front end portion (2) and the axle attachment portion (4) and formed integrally therewith. The spring portion (3) comprises a channel shaped profile having a top wall (30) having a wall thickness (tt), two opposing lateral walls (31) having a wall thickness (ti), and an open side opposite the top wall (30) and facing downwardly in use. The spring portion (3) furthermore comprises outwardly extending lateral ridges (32) formed at the end of the lateral walls (31) flanking the open side of the channel shaped profile.
