Installed OME 861/862 springs tonight, ended up sticking a 10mm spacer in the front. Gained an inch in the rear, .5" in left front, LOST .25" in right front, even with the spacers! I'm thinking the diesel and winch add a lot of weight in the front? I searched and searched but couldn't find anyone who had installed these on a HDJ81, but came up with nothing, so it was a bit of an experiment I guess.
Rides much better though, firmer than the stock springs, but not harsh. Much less squatting and diving, and less bodyroll. I also took it off the paved road for a quick test, and the body was much more planted, much less movement, much better.
Still on stock e-adjustable struts, always set to firm, the bushings were pretty bombed out when I was under there, so I'll have to address that at some point, might just replace the struts altogether, we'll see. I have Ironman 2deg castor correction bushings that I haven't installed yet, not sure I "lifted" enough to require them, but I'll see how it handles on the highway before I decide. Steering felt a bit dartier than I remember, is that a symptom of not enough positive camber?
I was hoping for at least an inch gain all around, but I bought them mainly for the handling, load carrying improvements, and I guess I got that. I snapped a couple before pics, but it's dark tonight so I'll have to get the after ones tomorrow now. Very easy install with a buddy, so it wasn't a big problem to have to do it 1.5 times to get the spacers in the front.
