A stabilizing strut, in particular for a chassis of a vehicle, in particular a Watt strut, is described, the strut having an elongate strut body which is designed as a profile. The strut body is formed as a profile which is open on one side at least in some sections along its longitudinal direction and the two longitudinal edges of which are connected integrally to each other at least in some sections axially to give a closed profile. Furthermore, a method for producing a stabilizing strut of this type is described.
