I am about to order a 4" lift for my truck. Which shocks would you recommend and why? Are the 9000's worth the extra coin?

 

I got the 9000s free with my 4" Rancho lift like them a lot. The ride is a LOT smoother than my 2nd Gen that I had RS5000s on, but the 2nd Gen had a body lift and was a SFA truck. Current truck is IFS and has a suspension lift, so it's not a fair comparison. Probably is NOT the shocks that gives me a smoother ride in my current truck...
