A nacelle drag-link assembly for a thrust reverser of a propulsion system includes a drag-link fitting, a drag link, a coupling assembly, and a vibration damping assembly. The drag-link fitting includes a base region and a coupling socket extending from the base region. The coupling socket has a first coupling aperture and a second coupling aperture. The drag link includes an inner structure end, an outer structure end, and a link body. The outer structure end includes a pivot area to link with a blocker door of the thrust reverser. A coupling assembly is installed through an aperture of the inner structure end and between the first coupling aperture and the second coupling aperture of the coupling socket. The vibration damping assembly is installed in contact with the drag-link fitting and one or more of: the drag link and the coupling assembly.
