Just installed the 9000's and I have to agree with everyone who beat me to it. These Shocks are magic! I thought the stock ride was pretty good until having a frame of refrence. The Ranchos are soooo worth the time and money. I just wish I had changed them out 40,000 miles ago.
I'm running them at 7 in front and 6 in back and it feels great. I have a Lux with rear air suspension and have no drop in the rear height to report.
