I am running UPR upper and lower control arms, as for the torque boxes, mine look just the same as they did when she rolled of the assembly line except for some light rusted areas. My theory on the torque box issue is that if you run an aftermarket lower and stock upper then you will have problems due to the different flex geometry in the two parts.

I have either run completely stock setup back there or totally aftermarket and I ahve had not one problem. There are 3 people that I know that have aftermarket lowers and stock uppers and all three of them have had to weld up their torque boxes.

I have been running this way for over 5 years with either drag radials or slicks.
