Hi Dysan 911. Re your question on air bags. I also just installed the rancho quick lifts in the front, which give a 2 inch lift plus have the 9000 shocks. I have the fronts and rears set at halfway. The air bags are 12 lbs emtpy. ( firestone ride rite). The ride is very good. No secondary vibrations, just one . It rides so soft, hard to describe. Best truck ride I have every experienced. Totally happy with this combo. The truck looks great with with front up 2 inches also.

cheers, sak aka sledder
