I just did a Calmini AAL setup and new torsion bars. A arms and shackles are in the works. I have 31' Wrangler MT/R's under it. A very nice setup.. I am not sure about the Calmini quick disconnects for my swaybar though.. there isnt really anything "quick" about them...
The job wasnt hard but any more than that and you are looking at putting in some serious time and you will want at least one other mechanically inclined buddy to help you out. Plenty of large C-clamps and tools help too.
You might want to talk to Mosi or Anti Tree Hugger. They have done that sort of thing before to an X.
PS - why do you want to lift a 4X2?? just curious....
