I just purchased a 92 xj it has about 3 inches of lift the guys said it has 4 but it doesn't sit that high. It has 2 adda leafs in the back with a 1.5" block. In the front it has i think 2 inch lift springs with goofy ass spring spacers that go in the springs and ajust up and down. I don't like much of this setup. I was thinking of buying 2 inch spring shackles and taking the adda leafs out and then putting urathane spring spacers up top in the front. The transfer case is already dropped 1 inch. how much lift can i put on before i need to replace the stock lower control arms and before the pinyion angle is to great.
