LOST JEEPS :: View topic - Iron Rock rear UCA mount WWdiesel review

$125 I think, or $140 for the mount? Then the iron rock is about $300? Hmm, I'll go check.
Edit: I ended up at about $436 for the whole thing as I sold WW back the mount that came with the UCA.

The iron rock is adjustable up to roughly 6" I think. It's at the absolute lowest setting with a plain OME HD lift. No problems with pinion angle at all! Only better angle as you can adjust it.
You'll also definitely get more flex as the stock set up is actually binding/holding the axle closer to the body.

I'm definitely interested. A few questions:
It looks as though the bolt / threaded rod (not sure which one it is) used for pinion angle adjustment needs to be cut. This is something that I don't have a good way to do. Do you happen to know what the diameter, length, and thread pitch of the original item is, and what the length needs to be after cutting?
As shown, can this be used at stock height? Ideally, I'd install this before doing the suspension since I need to replace my stock rear UCA and am not running any lift at this time.
Are any modifications to the Iron Rock UCA required other than to the bolt?
Apologies for all of the questions, but I want to be sure that I have a solid game plan for this both before and after lifting.

Cutting about 1/2 to 3/4 inch off the end of the large adjustment Heim joint will allow you more adjustment on the pinion angle.

Anyone with a chop saw or metal band saw can cut a little of the the end of the Heim joint. It could even be done by hand with a hacksaw, but would take quite a looong time. :roll:

For a stock lift you may want to do this? On a lifted vehicle I don't believe it is really necessary, it actually decreases pinion angle which is a good thing.

As to the Iron Rock arm, it fits perfectly and requires no modifications. :roll:

*Smacks forehead* Oh, duh. It's a Heim joint. Don't know why I didn't spot that initially; it's plain as day in the photos. OK, now things make more sense.

Yeah... I'd prefer to not go the hacksaw route

Knowing what I'm looking at now makes it a lot clearer as to how I can approach it.

Possibly, but I'd rather just replace it once and be done with it. My OEM control arm boomerang is in need of replacement anyway, and I'd like to be able to keep the Iron Rock one on there after the lift (only planning on about 2") is on.

Cool.
So what do you need from me to be able to send one my way? Don't think I can do anything about it until next month, but forewarned is forearmed.

Now for the $1,000,000 question. Where does one get URETHANE bushings for the unibody side? I hate those stupid rubber bushings, and MOOG hasn't made any of their "problem solver" bushings for our boomerang. I have considered making my own, but my time is limited and experimenting with resins doesn't sound like my cup of tea. Anyone ever found a solution for the rear boomerang?

WWDiesel - please check your PMs. I think the PM notification system may be broken again. Thanks.

I bought one of Wwdiesels rear trilink mounts, and the ironrock UCA. I haven't tested it off road much yet, but here's my initial thoughts: I had replaced the bushings and ball joint and the lca's 40k ago, so most people will probably get more dramatic results. But, the ball joint was very loose/toast already, and I was getting the wagging sway again. That's much better now, and it's quiet. I was under there two days ago installing the drive line as I replaced the u-joints, and everything looked good, but I need to get under there with a better light. I've towed heavy a lot, so I need to add an extra rear iso, which will make the rear bushings sit in an almost perfectly neutral position, which will help them last longer. They are at a bit of an angle, maybe 10 degrees as is, which is much better than how the factory one was! All around it's quite the upgrade. I can't imagine having to replace the factory ball joint every two years otherwise! My drive line angles went from pinion 8 degrees and transfer case angle at 5 degree, to both at 5 degrees which should reduce vibrations. i adjusted the iron rock to the shortest/bottomed out position. OME lift with no extra clevis, top plates, or pucks/ rear isos...

Sure thing, thanks for making this amazing mod possible!!! I accidentally posted this in the tech section, maybe less viewers? Maybe admin can move it to regular CRD section? Update: towed a CRD across town on my tow dolly, everything went well with the 6,000 pound load.

What did you pay for it? Do you think it will increase how much the rear end will flex vs before? If your lift was taller would you have issues getting a proper pinion angle?

I'm keeping it in mind for I feel I'm going to need a new rear uca in the next month or two.

This is catching my interest. Are there any photos / installation write-ups available? Thinking this might be a good thing to do as part of the suspension replacement planned for later this year.

I used the iron forge version (Ricky Parker original) of the mount..However, I did trim about one inch off of the center joint for more adjustment....

My driveshaft is setting at 18 degrees, vehicle setting on a lift, suspension at full drop. As the suspension is depressed, pinion angle decreases. As to the Iron Rock arm, it fits perfectly and requires no modifications.

The neat thing is with the Iron Rock Arm, if you lift later, you will have the ability to adjust the the Heim joint to whatever angle you desire. PM sent.

Have you looked at the Iron Rock control arm, it has some really stiff hard bushings, not like the soft mushy ones on the OEM arm. And I believe they are replaceable...

I have a 4" JBA lift. I started with the JBA Y-adapter with the stock ball joint set up which came with my JBA lift. The Y-adapter came loose due to my lack of thread lock use. I replaced it with the JBA bolt on 4-link. That worked well, but got noisy after a year or less. I kept trying to figure out where the clunks were coming from, but I never figured it out. I just replaced the JBA 4-link with the IRO tri-link and WW's bracket. I had a lot of trouble getting everything to line up, probably from not having a level surface to work on, but I got it in. I did not need to trim the threads due to my 4" lift. I'm not sure my pinion angle is right, but no vibrations from 0-70 mph. I'll recheck the pinion angle when I get a free bay in my garage. I have plenty of adjustment in either direction for my pinion angle. I'm sure this unit has less articulation than the JBA 4-link, but more than the stock unit with the spacer. It is quieter than my JBA 4-link was. I think I'll stay with it and sell my JBA 4-link.
