I'm toying with the idea of changing the rear suspension on my truck (again) in pursuit of ride quality. See signature. Presently the rear is Carli mini-packs on stock springs. Ride is good when towing our camper but pretty harsh unloaded. I'm sure softer shocks would help, but work against me with the TT hitched. From what I can tell the front axle is doing its job but the truck is severely imbalanced. Knowing what I know now I would shop harder for a megacab 3500 air assist or 2500 coil and add airbags.
If I'm looking at Thuren/Carli's softer spring packs, I'll also need airbags I assume. Last scaled RAW is 5900, but that was before bed cover, rack kayaks, extra firewood, extra child, etc.
If I'm adding the complexity of airbags (on board air, controller, etc) why not hunt down a set of rear springs from a 3500 air assist truck and then use an aftermarket bolt-on airbag fitment (since my frame/axle don't have the airbag perches). Looking at part numbers, I've found 68280127, 68349438, and 68273634. I'm assuming that the springs are dimensionally the same, eye-eye and width.
68280127 strangely can be had for about $520 a pair, delivered, but looks like an odd setup with asymmetric progressives on the bottom. So my question, for the 2015+ 3500 SRW air assist trucks, are the packs asymmetric or symmetric. See photos. All insight appreciated.
(EDIT: adding part number 68273634AA for completeness.)
