[04SuperHawk]

ok I have a 1998 JEEP ZJ stock suspention was waniting to get a lift, but , I don;t know what brands are better than the others. There are also quite a few styles of lifts out there. what is the best style to fit a 31-10.50 tire under it? can you really trust those coil spring spacers? how hard is it to intall the control arms, springs, and shocks. Do you have to get new drive shafts because of the length difference?
