I can attest to the AEV kit. I put the 2.5 dual sport kit on my 2011 rubicon. Ride and handling was way better than stock. And the lift was closer to 4” front and back. Of course there was some settling of the springs so it’s closer to 3” now. But it’s my daily driver, been out to Wyoming 4 times from Wisconsin with a ton of gear, RTT, and 35’s. I will definitely do another AEV lift on my next build.
