front springs

Ok so I scored a set of v-8 grand cherokee springs on ebay and was wondering what needs to be done to install them on a xj with a d30 front. Also how much lift to expect with them? Everything is stock except for 3 inch spacers on the front.

you can install them without any mods and it will give you from 1-1.5 inches of lift

you will need to center the front axle, lengthen the brake lines, you will need to address your lower control arms...

all this is because you are going above the 3-3.5" range

becuase with the 3" spacer you will be sitting at 4-4.5"
