Comments: Put this on my 89 Islander 4.2
I didn't buy a "kit", but rather purchased everything separately from different vendors, ebay, amazon and got the rear springs from a fellow member (Scramblered) brand new.
Rear springs ware CS037 with D24 extra leafs to bring them to "heavy duty" rating. Since I don't have a winch, I got the CS014 front springs (medium duty), knowing that I can make them heavy in the future with an add a leaf from OME.
I replaced the entire suspension with OME product - springs, greasable shackles and bushings, nitrocharger shocks, u bolts, t case drop, steering stabilizer and U bolts. Every kit I priced and added the extras not included in the kit, was coming in far above $1200.
For anyone considering this lift, I highly recommend it. The parts are machined unbelievably well and there is no effort assembling into the Jeep. All my blood was lost on tearing out the old.
ARB Dakar, who distributes and make the Old Man Emu stuff, was also extremely helpful over the phone with a bunch of questions I had. Gotta love great customer service.
Do some serious shopping, and remember that most of the "big" vendors will price match if you feel more comfortable (as I do) buying from them.
