...On our XJ that is. The reason I'm posting this in here is because A) since the kit is really aimed at TJ's I figured you guys would be more interested and 2) there'd already been some threads about the kit in here.
This kit is beefy. The tierod is a MONSTER! ORO's instructions are great (some of the best I've ever seen), and include lots of reference photos. They even go over how to set the alignment after you finish with the install. The kit was originally designed to go with their AiRock TJ suspensions, but it works just as well on other Jeeps. One of the early installs I saw was actually on a YJ.
Anyway, I got the kit installed saturday (11/6) and so far I'm pretty happy with it. The install went smoothly, and it's all pretty basic really - unbolt the stock stuff, bolt up the new stuff. There's not even any drilling required. The bolts that go up through the knuckle arms use an aluminum crush sleeve to deal with the taper, and boy is it solid once you get it all torqued down.
Technically you don't have to pull off the wheels to do the install, depending on your rim backspacing and tires, but I decided it'd be a lot easier to do everything with the wheels off and the front on jackstands. Pics from the install are at:
The new steering hubs raise the draglink about 3", and the tierod about 1/2-3/4". As you can see in the pics, the draglink is actually bent to clear the swaybar mount on the axle. At full left lock, the end of the draglink still gets pretty close to the bottom of my JKS disconnect, but it doesn't appear that it will actually hit (unlike the TRE on the tierod on my stock steering).
So far I've put about 50 miles on the kit, mostly highway speed driving, and even without a steering stabilizer (the kit's still in early production and the SS brackets aren't ready just yet) it's smooth and controlled. It's a bit loose though without a SS. Not like sloppy, but the steering wheel is very easy to turn now. This could also be from the reduced draglink angle being able to put more force in the horizontal direction. No signs of death wobble or vibrations or anything. And oddly enough, like someone else with the kit had reported, it seems more stable in crosswinds. It doesn't feel like I'm getting blown all over the road anymore.
There is a hint of bumpsteer though. It's not much, and once I get a SS on there I may not even notice it. The kit was specifically designed for a TJ with a trackbar drop bracket (like what comes with RE's long-arm kits) and the *stock* pitman arm -- the instructions specifically state to use the stock pitman arm. Since RE's XJ trackbar bracket doesn't lower the trackbar any, I'm getting the same effects as if someone ran the kit on a TJ with a drop pitman arm. It's not enough to me to even bother with though.
The new steering hub keeps the draglink alignment with the knuckle the same to maintain the factory ackerman steering angles. Of course, on a rig with a much wider track and much larger tires, I'm not sure how important "proper" ackerman steering is.
As I said above, so far I'm really happy with the kit. Angles are improved, it gets rid of the inverted-Y geometry, and the steering feels more responsive and precise. The only real downsides I can think of is it's not *as* easy to adjust the draglink as it is with the stock linkage, and I'll probably have to disconnect one end of the tierod if I need to remove the trackbar's axle bolt (since the tierod runs directly in front of the bolt).
