Comfort Ride Slipper Spring system w/shocks

Slipper spring setups used to be more common, especially on lighter trailers, but went away when the centre equalizer system came on the scene. There's no problem with unlevel, or stiffness, as suggested above. The main issue in their demise was wear in a non-replaceable area, mainly the pad welded to the frame. Shackles and bolts became wear points, but are easy to swap out.
