After I installed all 4 of these, one side of my LJ was sagging in the back. I thought it was the springs so Rough Country sent me out another set, but the same thing happened. It looked like it was an issue with my Jeep so I just installed a spacer and called it a day. The springs don't have many miles on them.
To sweeten the deal I'll even throw in the Rough Country windshield sticker (unused) that came with them.
