What setting are you guys running your quicklifts and rear 9000xls on? I just got mine on today and they are at 7 in the front and 5 in the back. It feels a little spongy still, but I havent put my airlift in yet. I plan on doing that this weekend.
In keep my fronts at 7, for city driving and crank them to 9, for long highway runs. I have Bilsteins in the back, so no adjustment. The air bags are usually at 20PSI.
