Well you will need to be able to build some parts as well if you plan on going that high. A lot of the parts you'll need won't be a direct swap over. Some things you won't be able to swap and may have to buy if you can't fab include control arms, track bar, and sway bar links. THings you can grab from donors include a pitman arm from a V8 ZJ will give you a 1" drop. You will want a bigger tierod too to go along with the big suspension. This can also be taken from a V8 ZJ. As far as front lift goes it's going to ride pretty rough. I'm not sure what springs will get you that high by themselves. I know that F-150/Bronco Coils will get you about 4-4.5" lift. You can couple this with some poly spacers for the six inch front lift. Working backwards from there you will need some new shocks and thats something you can't really get around safely. You will need to do a slip yoke eliminator at this point. Iron Rock Offroad makes a very reasonably priced hack-and-tap system if you are comfortable cutting the output shaft on your own and tapping it yourself. For the rear use full size Blazer leaf springs using the XJ main leaf first alternating between Blazer and XJ leaf springs. This should get you about 4.5" and then couple some GM full size truck shackles from 95-99 for another 1.5" to bring you to the 6" mark. You will need some longer brake lines as well. For the front use Chevy/GMC c/k1500 front brake lines which are 6" longer. For the rear brakes a Dakota rear brake line is also 6" longer.

Hope all this helps!

hey i was thinking about doing a axle over conversion for the rear it should get me approx 4' of lift and all i gotta do is cut and weld new axle mounts right?

yaaayyy math... ugh lol

Just make sure your cuts are done very carefully so you still have a good mount to weld back on. There are tons of aftermarket supplies that have full spring over conversion kits as well.

I've done this to a straight line car,it works well pay attention to brake lines,park cables and your electric bill
