From what I've read, the newer Rough Country lifts are better quality then the old ones, and both are better then the Skyjacker. If you save up just a bit more, you can get yourself a 3.5" Rubicon Express Standard lift. RE makes quality product, and they typically sit a little higher than their advertised height, so it's really between 3.75-4" of lift. If you go with the RE lift, opt for the Monotube shocks, not the twin tube. It's a better on road ride.
