...Even if your X was new, you should see at least 1/2" improvement in stance, and in ride quality as well.
That said, spring swaps are easy. Disconnect your sway bar links on the axle end. Disconnect (and remove) your shocks. Lift the Jeep one corner at a time to full flex--I like to put the floor jack under the frame right behind the control arm mount. The fronts are easy to get in and out. The back can hang by the brake lines, so I usually disconnect the bracket that holds those to the outside of the frame, right behind the rear tire. Watch your abs wires to the rear brakes--don't extend up so far that those stretch.
Happy trails!
