The option sets may have changed but when I bought mine, the Adventure Package came with air ride as standard. It's nice that it self-levels when loaded or hauling, I can't say that I've compared the ride between it and the sprung suspension w/o air ride however.

The downside is the expense if something goes wrong with it and a few have had clearance issues with the position sensors when using some aftermarket wheel & tire combos. The sensor position can be modified but it's worth mentioning so you'll be informed.
