If you want a good lift for cheap, pick up a set of front 4" coils and move your stock front springs to the rear. You can usually get a pair of 4" coils for as little as $99, sometimes cheaper if you buy used.
Veteran, thanks. A Jeep with front coils in the rear actually rides and flexes very well. You will need all the other stuff needed for a 4" kit, like shocks, TC drop or SYE, longer brake lines, etc.
