Bobby, I "borrowed" this photo from oldelmer1
This photo is one of the end hangers, but if you look at the Xfactor installation file page 2 (Google XFactor)... it shows the same thing on the center bracket for standard suspensions. They're using U channel instead of square tube. The end plate is thick with two eyes for a stap that bolts around the spring shackle bracket. It also requires removal of the shackle bolt and replaces it with a longer one to acommodate the thick plate.
