You know, I have asked this myself and found that the vendors state w/o air suspension. So I got thinking on this, how many are out there with aftermarket bags and after market shocks on them? Quite a few, I was one of them. Had Airlift bags with Bilstein shocks and no where did it say not to use these shocks with air bags. Why is this different? Sooooo, I just ordered some Eibachs for the front and rears and will be installing them this weekend, should arrive today! A lot of folks said Fox shocks would work, but dang, they are pricey.
I did call Eibach and they asked if I lived nearby (I dont't) so that I could bring in my truck so they could see for themselves if their shocks would work. I'll see how they perform......

 

Well, they are installed and WHOA! What an improvement. They really took out some of the jolt that the oem's had. I nice smoother ride too. Also, the oems were done at 70K!!!!!Glad I did it...
