Here's some pics of the install..
On the lift, getting ready to start. went from 6.5" shortarm w/2" spacers, to IRO longarm and 8" springs +2" spacers..
Drop Brackets that are being removed:
Started with the mounts and crossmember:
Then the track arm bracket:
The old destroyed trackarm:
Old 6.5" spring and new 8" spring (7" ZJ)
Drivers side arm on:
NOTE: directions say to leave the pass side arms intact, while you install the drivers side. I found this to be near impossible to rotate the rear of the arm upward to it's mount, requiring me to remove the pass. side upper arm, in order to easily rotate the LA up.
I'm tired..
Drooped:
DONE!
All in all, the install was quite easy, and straight-forward. I did have the luxury of using a lift, but even in the driveway, it'd been fairly simple, with the only exception being the spring-swap portion that I did.
The only other "glitch" that I ran across, was that one of the crossmember bolt/nut sections (pass side, rear/lower) where the middle piece joins the pass. rail piece, was that one of the welded nuts was a tad off, making it nearly impossible to assemble w/o modification..
As for your drill bit vs. tap question:
23/64 = .3594"
3/8 = .375"
I used a 23/64ths, but I had one.

Additionally, the 3/8" bit works fine, but the 23/64 bit allows for more thread surface.. Here's a pic I found to further explain what I'm saying..

That's the best picture I've seen of that bracket yet. It helps explain it a little better to me. Do you think you can take some more of it and explain how one would change caster?

Looks like a simple and strong design.you do know that the L/A system and the trac bar are designed for a 8" lift max, not 10". hope you invested in OTK steering also. good write up.

Pulled an all nighter and installed mine. Took me about 5 1/2 hours using the front yard. So far have only taken it around the block but the difference in ride quality is amazing. I guess everone is right when they say you can't beat a long arm. Really cool part is you don't have to cut any of the stock mounts so you can always conver back when you go to sell the rig.

thats exactly what i was thinking. if you dont like it, take it off and go back to adj. arms. just cant figure out the adjuster. anybody explain it with some pix please.

it's fairly easy.. the more you rotate the adjuster's top portion toward the front, the top of the axle is rotated forward, raiding your pinion angle upward.
Yeah, i do know it's designed for 8". OTK steering is next, along with front shocks.

Wow those arms hang low. Are those the "critical path" upgraded arms or whatever they are called?
So the entire front suspension is held on by 6 bolts that go into sheet metal?

Lets see, how many are on a stock front end that go into sheet metal?

Wait:
Did you install the passenger side link backwards? The bend doesn't match the driver's side.

Wait, so your comparing the stock mounts (there are four of them) to the IR mounts (there are two of them)? :roflmao:
I take it you have never tried to cut off stock lower control arm mounts. They are a PITA to get off, mainly because it is several 1/8'' pieces of steel stamped together. They arnt going to fail.
People havnt had any issues with the IR stuff, but it still looks sketchy to me. It is literally six bolts holding up the tranny, tcase and then entire front suspension. Is that right?
There is a reason people like RE and T&T.......

I haven't heard of anyone having issues with the IRO setup. Its all in personal preference, as far as I am concerned.
