IRO's steering doesn't impress me. I do like many of their products but their steering isn't one. Here's why,
They start with 1.25" solid. Great start.
Then they drill & tap it for 3/4" heims : smaller, weaker threads than the 22mm (7/8") stuff you get on your factory drag link. A step in the wrong direction.
The fact that it's heims, to me, is also a step in the wrong direction.
Then you have the setup of the heims. They want you to drill the steering knuckle out & mount not just one steering link, but two, in single shear and on a single bolt. That single bolt is hating life, I can tell you. When you push the drag link, through the top of the bolt, to passenger's, the tie rod is pulling it to driver's. It could only be worse if the joints were stacked on each other.
The kicker? They supply it with a 1/2" bolt by default & 5/8 if you specify.
1/2? Are you kidding me? WTF - that's the thread size of the factory tapered joint. With heims? Two of them? On single shear?
You'd need a lot more bolt than 1/2" for me to feel good about it and it would have to be an extremely close fit in a larger / thicker steering arm than the XJ has got.
Yeah... I wouldn't use the IRO setup on my steering.
On the other hand, their suspension parts seem to be well built.
It's an expensive purchase, but getting the WJ stuff from Clayton's gives you badassery in the brakes department, a full front end refresh, beefy steering & it corrects your geometry some as well. This applies to any WJ swap but Clayton's makes it simpler to get all the parts. Hell, it could only get better if they threw in a 6 pack or if Playboy Bunnies delivered it. Or some dudes. Whatever.
