Don't have their lift kit but can tell you at least in my experience shipping is very slow took over 2 weeks ( over a week longer than estimated) to get my track bar and u joint and that was after multiple calls and emails

I ran there LA kit and loved every second of it! Parts always arrived fast for me and everyone at IRO was great to deal with. I just parted out my XJ. Another person to ask would be Moparboy. He runs IRO and actually bought my kit to run under one of the Jeeps in his fleet. Josh @ IRO and I went back and forth a few times as I was building my HP60 for the front. Looking at how there setup would fit and work around the new axle. Great people to deal with in my opinion.

i'll just quote myself from another post here.
iron rock is the only company that offers this stupid piece to adjust caster and have A SINGLE 10mm factory bolt to keep the axle from flopping around.
i have broken more 10mm bolts in my suspension than i care to count and know of many others. even some who have broken BOTH 10mm upper control arm bolts when running a 4 link. they gloat about how you can never break thier arms and all that jazz. but what good is a strong chain with a weak link?
and iron rock isnt a true 3 link. its simply a radius arm with essentially one upper link taken out. others might call it a wristed radius arm.
rouch country,rustys, and rubicon express are radius arms. they have 4 points that connect to the axle.
dont get me wrong. 3 link setups can be great. but they have to be done right.
another thing that bugs me is the fact that they use all rubber bushings that connect to the axle in a non binding setup. this translates into a looser feeling suspension, and axle hop that becomes more pronounced as the bushings wear.
its a system that works for some people, but it just scares me that people are putting a suspension thats arguably weaker than stock on rigs that see more abuse than stock.

As much as I like the kit, and can vouch for the quality of 90% of the assembly, I also worry about that one spot. I realize why they did it (to use the standard axle end bushing) but it wasn't a good idea for two reasons. Now the single bolt is responsible for any/all axle wrap and the standard bushing is no where near stiff enough to resist the forces of the axle. I run their radius arm setup and haven't broken anything yet but have personally witnessed the excessive wrap of the axle under power and braking. I have suggested this revision to IRO but it seems they don't have THAT many issues with it; although its on their "to do" list.
Unfortunately outside replacing the factory bushing with a solid piece you can't reinforce the assembly without re-making the caster adjuster bracket.
It's a weak spot, for sure, but I've been running the arms for little over 2 years with no issues outside replacing the JJ bearing races. If it break... there will be carnage.

the pic i posted was my buddies setup. you can tell its been damaged. he contacted iro and they said they would send out a new one, for a price that he wasnt willing to pay for a part that would likely fail again. he now has a 3 link and is much happier with it.
if that one bolt or that caster adjuster bracket fails. so does your driveshaft, shocks, and possible steering, brakeline, and transfercase damage. ive had it happen to me with BOTH upper control arms, (not just one like the iro setup)
