It would make it much more ridged for sure. Just machine to fit the tube and if its needed for each side make two of them. That way its a solid piece from where the bolt goes in to the frame attachment point. All don't and simple easy fix I think.
**** one could make a u channel to wrap around the frame rail with the bushing adapted as a part of it with a fitted hole to allow more holding ability without the k member to move around once in place.
