haha ok I was just wondering. I've never seen the more experienced guys defend IRO becuase of how weak it is supposedly. but I've never seen anyone break anything...
yes I know that's what I said O.o

Only matters if you're going into REALLY gnarly off camber stuff. For FSRs or mild trail riding shortys and drops are more than adequate.
Besides, having a less capable vehicle allows the driver to work on their technical skill. I've always felt that a person's build should reflect their level of skill.
If a vehicle is too overbuilt for the driver's skill level they are more likely to drive themselves into more danger than they are capable of driving themselves out of. I've seen (and experienced) this more times than I care to recall.
Besides, radius arms do not maintain consistent caster. the more the suspension droops the more caster you lose. That's why the 4-link was used to begin with: maintaining steering geometry as much as possible.
Mind you, you're unlikely to see enough caster change on the road while you're driving to matter and caster change doesn't really matter a whole lot offroad so the point is kind of moot. But I thought I'd bring it up since no one else had.
Just my $0.02

I dont see how a y-link on only one side of the radius arm setup and not both will cause any less binding. In a y-link the upper control arms are attached to the lowers. I see no added benifit in running a y-link on only one side on a radius arm setup. Maybe Im wrong? if someone wants to enlighten me.
this can lead to binding, bushing wear, mount damage.
and since the IRO kit eliminates one of the uppers, it now will only have one side trying to twist. so it's geometry starts to resemble a 3-link, which has ZERO binding.

although i personally would not run an IRO kit, one of my good buddies runs there 6.5 kit and loves to jump his jeep. he jumps it enough that he has broken a set of leaf springs and bent the short side of a d30 housing....but the IRO kit has remain undamaged.

the binding that people refer to in a standard radius arm setup is cause by the geometry of the system. it causes the arms to fight eachother during articulation. during travel the radius arm wants to "twist" the axle and having a radius arm on both sides mean that the arms will be trying to "twist" in opposite directions from eachother under flex.
this can lead to binding, bushing wear, mount damage.

there's already so many threads about why you shouldnt buy an IRO kit. just turns into a long debate lets not go there haha

As for the tons of threads about not buying the kit???I found two. And he complained about a bushing getting tore up. Dunno what his issue is, because my upper controll arm mount bushing is still perfect. .
Im not trying to fight with you. I just cant find proof. And I personally have beat the **** out of my jeep. I wheel it alot. And she keeps goin. I havent even had to re torque anything. I have but everytime my wrench beeps, without budginh the bolt or nut

I have the iro kit. Tell me a reason why. I dont give two ****s what some guy says or what this guy's buddy said. Give me hard. Proof. You wanted hard proof on the binding issue. so unless you have hard proof, or personal reasons as to why I should buy this kit. Dont talk down a company, or a suspension system. Your opinion is fine, but most come on here not knowing ****. And for you to bash a company with heresay is just plain dumb.

I even said on the last page that I've never seen anyone have a problem with the kit. only satisfied customers. and I wasnt the one who asked for proof about a binding issue. so dont get your panties in a wad

And I personally prefer flex, reliability, and a company that stands behind their product.IM NOT SAYING YOU DONT GET THIS SOMEWHERE ELSE. Im saying this Is my personal experienced.
