I am running the Rough Country and it was an OK lift actually a pretty good lift for the money. Rough Crountry lifts are I think superlift. When mine arrived the springs had superlift all over them. Made in India or something.
My friend has a Pro-comp. I think he got a little more lift for the money. His at the time was only 100-200 dollars more. we ride the same trails and my springs are creeking and popping like crazy. His hardly makes a sound.
I really want to try the Rubicon Express next time around but it is over 1100.00 bucks for a CJ.
Now would be a good time to go with YJ springs as some lifts like the Rubicon Express do.
