my own personal notes:
a long time ago in a galaxy far away I had this Jeep you see running up the hill in my little avatar picture.
it had 260 in/lb rancho coils + spacers for 4" lift & some for ford truck shocks I can't recall off the top of my head.
the rear was MJ shackle, XJ main leaf + everything but the main from a late 80s/early 90s 4wd dodge dakota.
solid 4" around, rode decent, flexy as hell for what it was, and it was THE MOST BALANCED XJ suspension I've ever seen in action personally. it worked so damn good, that when I went to 36s, I didn't change anything, I just cut and beat and welded on the XJ until the tires stopped rubbin.
I'm building a "CheapXJ V2.0" so to speak, and the only thing the previous one didn't have from the junkyard was the front coils.
