just to update this. The shocks did settle down after a while but still a very stiff bumpy ride. I really didnt care for the billsteins, like at all. If you love the ride from the factory you will most likely not care for these. After some research I found out I should have ordered the monroe reflex as its a much softer ride but you will lose some stiffness on corners. Oh well, selling the truck anyways. I have a whole new beast to contend with, a 2009 yukon xl! Of course right away when I purchased it the service suspension light was on. This time I'm going to go with the arnott system and keep the air ride working.
