XRF and the Napa Chassis parts are the cheaper decent solution now, but, even they can have issues if one is dealing with rough roads. Just beats pretty much anything into submission.
Dodge did not copy Fords cross over steering, it is completely different. The Ford cross over is actually easier to retrofit to the Dodge trucks than the Dodge system. The one problem I can see is the sway bar will have to be changed also to accommodate the newer style Dodge cross over steering.
