I had a set of super springs on my last truck and I am considering a set for my current truck. They work only when needed, the rest of the time they are just along for the ride. I liked how they kept the front and back of my truck level when I dropped my TT tongue onto the ball. My new truck dips a bit in the ass end under the load of my TT causing the front of the trailer to dip down as well. I would highly recommend them.
