I personally don't like the look of the way they set up the passenger side knuckle all stacked up and the way the drag link is shaped. That's a personal feeling, more that a factual opinion.
I do see a couple IRO steering set ups for sale on CherokeeForum right now - both say almost new in good condition. Neither of them say works awesome, will miss it, etc.
Although I run a few IRO steering parts, that is not one of them. I've got Go-Fer-it inserts on the shelf and I'm going to run a RHD draglink flipped to match my already flipped driver side TRE.
Heim Joints are not "legal" in most jurisdictions so be mindful of that if you drive it much. Heim Joints tend to get a bit noisy quick as well. Not to the point of failure, but just a bit noisy. YMMV
'00 XJ - Somewhat modified
'01 Venture - high mileage, paid for, shut it
