Installed a beefed up K Frame and Borgeson over the 4th of July

Oh it helps. The steering box mount and LCA pivot tubes are definitely known to crack/fail. The welds on the steering box mount on the one I have in my Duster were almost totally failed, the steering box would rock back and forth almost a 1/2" in each direction when the steering wheel was turned before the steering arms moved. How much the seam welding helps the overall chassis stiffness is probably a point that can be argued, but it can't hurt.
