A stabilizing strut for a chassis of a vehicle has an elongated strut body made of sheet metal which has at least one first eye at a first longitudinal end and at least one second eye at a second longitudinal end. The strut body has a curvature at least such that the strut body lies completely outside an imaginary connecting straight line between the at least one first and the at least one second eye at least in a partial region. The strut body is built up from two individual sheet metal parts which are arranged one on each side of a longitudinal center plane. The two sheet metal parts are joined to one another between the at least one first eye and the at least one second eye at their peripheral edges on a longitudinal side of the sheet metal parts oriented towards the imaginary connecting straight line, at least over a partial length of this longitudinal side of the strut body which amounts to at least 50% of the total length of this longitudinal side of the strut body. The surfaces oriented towards one another of the two sheet metal parts are spaced from one another. The peripheral edges of the sheet metal parts on the longitudinal side oriented away from the imaginary connecting straight line are not joined to one another, or at most are joined over a partial length of this longitudinal side of the strut body which amounts to not more than 50% of the total length of this longitudinal side.
