I still can't help but think that something isn't right, either with your weight or expectations.
Airbags provide up to 5,000lbs of load leveling assistance, why do you need more?
The HD SS are also 5,000lbs of leveling capacity right? 10K is leveling capacity is 4500 or 5500 territory.
Are you overloaded or trying to get the truck to empty height?
I still don't see how SS would be your initial go to for sway/load when you already have airbags. What am I missing in your setup? It doesn't make any sense to go SS over a swaybar, they cost more and do less for sway.
Have you weighed your rear axle? If the bags aren't cutting it you stand a good chance of being way overweight on the tires.
I am going on my 3rd year with a sway bar and I haven't driven 1' in the 25K miles plus where it has been anything but an improvement, empty or loaded. The claims are they limit off-road sway, but I have yet to notice it... Then again I am driving 8,500lbs with a 160.5" wheelbase, it's not exactly an off-road setup (but I do lots of miles on uneven back roads where traction and articulation are challenged. I have also done a bit of wheeling in my past and know what' good articulation looks like). The SS will probably limit compression travel far more than a swaybar, as they even have an effect of level compression where a swaybar doesn't. There is no feedback, kickback, or hop empty, just a very stable truck. It is a little more work to get the spare in, but once your use to the sway bar you can use it to your advantage. My spare is 2" taller and 60lb heavier than the OEM spare.
My only complaint about the swaybar is that I didn't do it sooner, it should have been done on day one.
