I'm amazed at how many people throw out the "Binding" concern when all else fails.
Radius arms are proven performers.
If you're dropping an axle that much, you need to invest in some limit straps.

How about, increased stress on control arm mounts and bushings during articulation.

Straight from iron rock
Our suspension attaches to the axle at three points, but using only 2 arms.* A typical 3 link will have two lower arms and 1 upper arm, all independent of one another.* Most radius arms have 4 axle attachments using 2 arms set up as a double y-link.* Our system would be classified as a radius arm setup being that we use the y-link.* The advantage of a single y-link system over a double y-link is that it eliminates a lot of the natural binding that occurs through the suspension cycle.* Please let me know if you have any other questions! I'll be happy to help.

IRO uses a radius arm y-link

It dosent explain. Im looking for some science to it. You would think that the uppers would not affect any binding because they are fixed and go along for the ride regardless, so it shouldnt matter if it has one or two ylinks in a radius arm setup. I just dont understand the "binding thru the suspension cycle" because there is a double y-link as opposed to single. The movement of the arms is not affected by having on not having that y-link because it is fixed to the lower arm which is the one doing all of the movement.

I recently installed RC drop brackets on my XJ
Close to 7" of lift and upper CA's are level, lowers are close to level.
I couldnt justify the price of a long arm kit.
Youll need adjustable control arms with anything over 4.5" lift but you want them anyways due to the stockers being roughly the strength of a wet noodle.
Pinion angle is straight (another benefit of adjustable arms).
All together i have less that $1000 into the lift and it works well.
Started with a 4.5" teraflex and went from there.
I agree 100% with everyone on building your own system with parts from different manufacturers to get what you want out of a system. Youll save a ton of loot also.

Correct. Lol
It works for me and if you would have witnessed the abortion i performed years ago dropping the t case you would know exactly why those t case crossmember bolts are not coming back out. Haha.
Broke all 4, drilled em out and tapped the holes with the wrong thread. Got pissed and just twisted some BA grade 8 bolts in. The crossmember hasnt budged since. I keep telling myself that sooner or later i will replace the nut sets like i should have, but it just isnt happening. Lol.
