Snap a pic of the Cv joint at the TC. That would be my only concern. Although You have less to worry about since RK coils are rated for your 4 door. Height shouldn't be too extreme. Adjusting the ends. Hmm, not sure. With my TF joints, they had to be turned 360 or the joint would be crooked. 1 turn for me was about 1* iirc.

Did you check with RK to make sure they sent you the right CAs? The ones you have may be for a larger lift. Every adjustable CA I have installed could be shortened by at least 3-4 full turns.

How does the Jeep drive?

I think there is only one RK front upper, lower, and rear upper.. Two rear lowers.
The rear uppers are only used with the longer lowers to move the axle back. The shorter rear lowers are the ones in his kit.
I don't know how RK is set up. Some company's arms will adjust to stock length. If not uppers are used for pinion/caster.

If I can't shorten the LCAs any, is there any other suggestions besides ordering adjustable UCAs?

Is what I'm setting at now gonna tear things up or be a safety concern?

Could shorten the arms themselves. Prob not worth the cost if somebody is doing them.

Problem? Just keep a eye on the Cv joint.

Do you have a lift height estimate ?

I have stock bumpers front and rear and rubi rails with Ace rock sliders so my jeep is fairly light at the moment. It appears that I gained 3" in the rear and 4" in the front (rough measurement).

Ewe ... Hopefully she settles some. Def try getting those arms back.

That is exactly how I lost my DS. Running 6* caster and 4.5-4" front/rear height.
I guess if I can't then I may have to look real hard into getting the adjustable UCAs. Looks like that would be another $250...uuggh.

Just added the rough country front CA drop brackets to my '11 JK with 4 inch lift and 35s.. All I can say is WOW!! What a difference in ride and handling quality. I fought with ordering new adjustable CAs or the brackets.. I don't do any rock crawling so clearance wasn't a big issue.. Didn't lose much anyway. I am just amazed at how much better it handles. We'll worth the 90 bucks!!

Are you sure you measured them correctly before torqueing the jam nuts? I have the same kit on a 2 door and with rk's measurements the castor was dead on. Each side should have the same amount of threads showing. Maybe I got lucky???

Pretty sure. I measured twice before installing. Center of bolt hole to center of bolt hole using the measurement for 4drs give in RKs instructions.

Yes. From the RK instructions..... 2.5" Front Lower Control Arm Assembled Length = 23 1/8"

Also, I did a lift height measurement on the front based upon a diagram showing stock measurement taken at the shock tower and also taken at the spring perches. Based upon those measurements, I ended up with 3 3/8" of lift on the front.

I saw that :happyyes:
Do you have a bumper/winch ?

231/8 Is common if that's what they list.

No, I don't have an aftermarket bumper or winch yet. On the list though. ;-)

I haven't had a chance to get back under there and take one of the LCAs loose to see if I can shorten it any yet. From what I remember and can see there isn't any real visible threads showing so if I can shorten them any at all, it will only be maybe a half (180*) turn. The krawler joint looks pretty symmetrical in that the protruding sleeve looks like its the same length on either side, so I don't think getting only a half turn will misalign anything.

I also e-mailed with Jason at Krawl-Offroad.com whom I purchased the lift from. He said that, "RK is saying that a castor of anything less that 6* is normal for this setup. So with you being at 5.9*, we should be good. That is for the 1.5” and the 2.5” lifts." My only concern on that is if they are basing that comment on only 2.5" of lift. Although this comment was after I sent him all of my info including lift height.

I think I am still going to:
1. re-check what numbers I get by doing the angle measurement off of both circles on the housing
2. try to get a measurement off of the pinion flange
3. take one of the LCAs loose and see if I can turn it (shorten) it any.

I figure it can't hurt anything, right? Who knows...things may have settled in some since first putting it on and now driving it around some.

It seems to drive just fine both in town, on the interstate and on a real beat up city road.

Yes !! that's the key "actual height" although RK did lower the new front coils by 3/8 or so compared to the first gen.
You won't find anybody running close to 6* with 4" of lift. Like I mentioned in my post. 3/3 or even 2/4 (now this is with a double carden) you do have a little more leeway with the stock DS, but risk CV failure.
6* is where I was at with TF lowers and my shaft went bad.
