it does exist as I have one. I have a 5K+ camper on the truck and you can look at picture I posted of the overload spring and they are not being used with 5K+ sitting on truck. I measured the distance from trailer ball to ground before and after loading camper and it measures the same. I cannot say for sure but seems as tho this is a full air suspension rear end.
I don’t think the lower leafs with the bumper is an overload spring. I believe it replaces the link arm of the earlier version to prevent axle wrap.
Looking at the design, with the newer version there is no difference in the frame, no need for a link arm bracket.
