I hate the answer, but this is a classic "It Depends" ha. I've got Currie 4", and I have to disconnect lower CA and shock and sway bar disconnect, and Jack up the other side then I can remove the spring, and then CONNECT that Lower CA and do the opposite to the other side. 100% zero possibility to get it out without the lower CA disconnected. Luckily I don't have to disconnect the track bar.
