A damper usually tries to compensate for trouble elsewhere, such as an incorrect sector preload adjustment or a bent steering arm or drag link that puts the "straight ahead" position of the steering gear somewhere to one side or the other of the steering gear center point. Dampers just try to hide the source of the real problem, like bent or worn parts. I think I'd prefer to spend my time and money on fabricating an adjustable length drag link or putting the steering system back to "as new" condition.
