Re: 99 ford ranger
wooden 6 inch blocks for 6 inches of body lift or stack 2 sets of 3 inch body lift kits together lol
6 inches is hard to get i think, especially on the cheap, you could crank your torsion bars for 2-3 inches max and get shackles in the back plus 3 inch body lift for 5 to 6 inches. or spend money and get an expensive ass suspension lift.
but this post goes in the suspension tech, and you should read, there are a lot of lifting questions already asked.
99 extended cab, 4.0, auto, 33s, 4x4 lifted with some stuff done
98 2wd 2.5, 5 speed, dropped with some stuff done
