I am up in OC. Did you return the coilovers? I just bought the front/rear King 2.5 res with adj. a couple of days ago and was looking to go with 4.5 AEV springs . What route are you going with the front? Any idea how a front bolt-on coilover would do with a rear King 2.5 w 4.5 AEV springs (frankenlift I know)? I need a lot of spring in the rear due to the weight of my Jeep and how I use it. I could return my front Kings.
