You wouldn't have to remove your lift kit (and it's not really possible anyway without custom fab work). The good news is that the Rough Country lifts use 2" stacked blocks for the rear, and the rear shocks included in this kit will technically work at 2" of ride height over stock. That being said, if you're going to be using the Stage 5 kit to its full off-road potential, then stacked blocks really aren't that great of an idea, and you should probably look into doing a single 2" block/add-a-leaf combination instead. As for the front, you have a couple of options: 1). You can run the ICON coilovers at a 0" factory ride height and simply reuse the Rough Country Kit's strut spacer. 2). Set the ICON's up at 3" of ride height, just use them by themselves, and lose 1" of front lift. 3). Use the ICONs at their roughly 2.5" out-of-the-box ride height and add a 1.5" leveling kit on top of them to get to 4" of lift. Your only real issue with the front coilovers is that you may need to find a different mounting location for the remote reservoir, since I'm not sure if you'll have enough hose length to use the standard mounting position while running a lift kit.
