Thanks guys, appreciate the input. I understood the benefits of the RK 4-link, but how much of a performance gain is found over the Curries I do not.

I am trying to get the best "bang for the buck" while attempting to keep things relatively simple. The price difference between the RK 4-link and Currie uppers and trac-bar isn't enough for it to make me choose one or the other. I just want to do it right the first time.

I'm curious what the Jeep Forums/TJ section big 4 thoughts are on the RK 4-link are? (Blaine, Gerald, Jerry, NeverMonday) I'll have to ask Gerald what he thinks when I order my Currie rear lowers in a couple of weeks.

If you understand the benefits, then the performance gain should be apparent. Currie arms + the rear Currie track bar with a JJ will do very well and likely won't bind throughout the entire suspension travel. But you've still got the axle moving laterally. I think the bind is a bigger issue that that so if you don't want to mess with cutting and welding, the full Currie kit is a great route to go. Just make sure you get the rear bar with the JJ setup. I like the RK setup because I can drop that rear axle straight to the ground. No binding and no limit factors before my shocks and CV joint. I also like the fact that my rear passenger side doesn't squat during acceleration anymore. Everything is balanced.

Imped, you're running out-board shocks right? My plan has been to do this kit along with moving the spring perches and out-boarding the shocks. It sounds like you really like your set-up. Anything you would do different? How does it ride on the freeway?

I have the rear RK set up and it is great. Gotta ask though, why RE lowers? Why not RK lowers?

Well, I already had adj. RE's up front and I liked the strength of them, so I used them in the rear. I like their flex joints better than RK also. RE just seems like better quality to me. Why RK over RE?

Not saying anything bad about RE because I have never owned anything from them, but RK arms are solid, not tube that could bend under less force than solid. On that note, I think if you were to bend either, you would have to take a pretty darn hard hit and would probly end up with other problems as well.

On the joints, I love the RK joints and they seem bullet proof to me, but hey, if you already had the parts and from what I gather, RE is a pretty dependable and reputable product, I say use them.

My Jeep rides better than most. The RK setup won't hinder the handling or ride at all. It does raise the roll center a bit, which will allow less body roll. The outboard shocks allow even less body roll. Overall, the rig is super stable and rides great.

Yes, definatly. I am very happy with the RE arms. I did get RK front upper adj. and they are good too, but the only thing I did not like was that I had to bend the mounts on the frame side for the CA to fit. But otherwise just as strong and solid as the RE.
I extended my front wheelbase about an inch with both of these too, and it's real nice... clears those bump stop cups!

Very cool. Thank you. I'm working on getting the kit (new in box)from a guy on another forum. If I don't hear back from him in a day or so I'm going to order one up. 48 hours of overtime this cycle will make for a happy Jeep.

I was hoping to skim the instructions, but they don't list any on the web site. I know Imped had a little trouble setting up for his pinion angle. Any advice on setting up the truss?

I would recommend setting it up ~12 degrees forward of square with the pinion, so 78 degrees relative to the pinion if looking at it from the side. I set mine at 90 degrees and ended up not having enough adjustment in the arm to move the pinion high enough where I needed it when running in the inner holes. If running on the outer holes, square will work fine. Definitely tack it first to make sure you'll have plenty of adjustment for future needs.

Thanks man. I think I will have to call them when I can. It's "Recommended to be used for lift heights ranging from 3 to 5 inches." With 4'' springs and a tummy tuck (soon to be a Savvy one/more clearance) I'm worried if that is too much. In my head it seems like it would work fine, but i'm no Blaine that's for sure.

It will work just fine. Just weld the truss on correctly and you'll be fine. What's your pinion angle right now? Let's say it's 20 degrees. Tack the truss on 15 degrees rolled forward and give it a try. If I remember right, mine is welded in 13 degrees rolled forward and my pinion angle is around 16 degrees. So my truss is almost upright (3 degrees back) and running the joints on the outer holes, my arms are as short as they can go. With them at the inner holes, I've got each end back out about 1/4". Still a ton of room for higher pinion angles (which I'll need with the flat skid), wheelbase, etc. Just tack it on, set things up exactly as they'll be, and fully weld if you're happy. I would recommend setting the truss up so it's a few degrees back from being upright at static ride height.

With the truss placement, another way you can be sure it is positioned properly is if the truss does not extend out past the diff cover when you have the axle sitting at the correct pinion angle.

Do not use the alignment tool that is provided by RK.

I would definitely tack it first and check clearances before fully welding it in like Imped suggested.
