so i got my axle, trying to decide coils or leafs. i'm doing this project on the cheap cheap.... i want to know if i can use my current 4.5" lift coils or if i do have to get XJ coils? if i can use my current ones i want to do coils but if not i'll do leafs just for simplicity. I've done a ton of research and have not come up with the answer i want. i read that coils are easy but i don't quite understand the geometry but if thats the route i take i'll do some more investigating
