Yes and No.....
There have been a few guys down here that have put on the Ironman lift with mixed results, One guy got 1.5 - 1.75 inches of lift and thats all he wanted, (but was advertized as a 2.5in lift) another guy went up in the rear but got no lift whatsoever in the front, he had to then put in spacers in the front to get any lift. There is another guy right now (by Wedensday) having the lift put in, he actually told the Ironman guys of the feedback about the lift on Ausjeepoffroad.com (it not being very positive) and then they said they would send two different lifts and make sure all went right (bit of a reaction because the fella getting it done said he would post up the results on the Australian forum for all to see, so I think they want a positve review

)
Old Man Emu is kinda the way most folks go, but, there is also another option. King Springs here in Australian make the OME stuff to specifications supplied by OME, now one of the KJ guys down here (you all know him as Ozltd) CRDSTU has had custom coils designed for the KJs to specifically address the issues of constant ride height and no sagging. He has specifically engineered a coil for the front end of the CRD that holds the front up even with bigg bullbars and winches and wont sag, as well to add to these he has just done a set of rear coils that specifically hold up the rear of the KJ even with a major load in the rear. (about 4in lift)
I am currently testing these rear coils and they are terrific, I will be putting up a post about the instal and how they perform offroad soon.
