The spring retainers look fine. They are in the correct locations. What possibly happened is that your springs are installed on the wrong sides. I've read that different spring rates are used on each corner of the Rams. So maybe the one you have on the drivers side is actually the passenger side spring that has a lower rate causing it to sag
Maybe try pulling your struts off and swap sides and see what happens. It's worth a shot to do that before forking out the money for new springs altogether.
