I put these on my 2009 wrangler rubicon and instantly felt the difference.
I replaced my stock arms with the Rock Krawler Adjustable rear upper and lower arms. Installation was very straight forward. Preinstall adjustment to the proper length was very simple with opposing threaded joints, then tighten jam nuts while in a vice. The hardest part of the install is the wingnut on the passenger side. The trick is sliding the tab on top of the wing nut into a gap in the frame to hold it in place, then center the nut with the bolt as you tighten. With the Rock Krawler recommended lengths, my 37's are centered in the wheel well now. Ride and handling has improved overall, with more control in all aspects.
