just my personal opinion... i can't see how RAS can still function with the airbags aired up to give the benefits it normally does (not that it won't function)... more or less you're getting a progressive spring rate with RAS. with airbags, you're increasing the spring rate so to speak... so (and i'm making these numbers up because i don't know the real ones) if your factory springs are 500#/inch ones and RAS currently progresses from the 500# unloaded to a rate of 700#/inch after an inch or 2... you put airbags on and increase the spring rate functionally to 625# aired up, are you going to get to a weight realistically, loaded up, where you have the benefit of the progressive rate? i don't know, but i can't imagine it... worst case i imagine, they increase your spring rate to where it feels like you have a super stiff (worse than a 90's f350) spring rate in the back with both.

on a side note, i noticed the language you choose initially and i assumed you weren't under the false assumption of it actually increasing your payload capacity... normally when someone doesn't understand that on here, they mention specifically increasing their payload or think it somehow is a license to not use a WHD when exceeding the 5k/500 pound weight rating of the receiver... you mentioned specifically sag so basically, thank you for increasing my faith in truck owners
