I've got a 2011 trail that's highly modified and I've run both on it. First off, both are great so you can't go wrong.
OME - bargain pricing, tough as nails, easily a 100k mile suspension.
ICON - top performance, fully customizable, plush, spendy
If you're wheeling it heavily and don't mind spending some bucks and occasional maintenance go Icon. If you want something functional and inexpensive that you can forget about go OME.
First off, I've seen your build thread on t4r and it's impressive. As fun as some of that rock crawling you do looks, I just don't think I'll ever be doing anything close to that. However, I would like to make it to Moab within a year.
That being said, I'd say the wheeling I do is moderate when I go. The stock setup just wasn't cutting it and I needed a little more clearance. I currently have Daystar 2.5/1.5 spacers and to me, the ride has gone to crap. When I go over speed bumps the rear seems to "hop" now too.
I like the idea of a plusher ride like y'all have mentioned the Icons have. Is the OME ride much worse than the Icons or the stock setup? For the kind of wheeling I do in my head the Icon's seem to be the way to go. But in reality, the OME's seem to be the best choice for the wheeling I actually do.
The idea of lower maintenance is a plus too. I'd love to say I have lots of extra time to work on my truck and be a do-it-yourself'er, but that's just not the case right now.
So I guess it comes down to ride at this point....
Thanks for y'all's advice.
