These weld on tabs to convert your 94-98 Ram 4x4 truck from the older Cobra style sway bar mounts, to the 98+ rod end style mounts. This conversion allows you to run aftermarket sway bars like Thuren without issue. Please note this install requires that you cut off your factory sway bar mount and weld these on, so it's not a bolt on part. That said, it's well worth the effort to move to the eyelet style sway bar design!
