i think i know the answer to this question but im gonna ask any way. i completed the rc lift about two weeks ago and today i was out laying under my 4 door jk, checking nuts and bolts, when i noticed the coil springs kinda torqued at the bottom as if the axle was forward a bit. i was thinking that the solution to this problem would be easily fixed with a set of adjustable lower control arms. am i correct or will i need uppers and lowers. if any one could help i would be greatly appreciated.

I installed this lift this weekend on my 2 door. I used Currie arms front and rear and set them per Eddies instructions in the tech write up section. My axles look centered and my coils look fine, however I have flighty steering as if I didnt end up with enough positive caster. Did you have this problem after the lift?

I have an appointment at the alignment shop this morning. Hopefully they'll straighten it out.

i do notice a slight (very minor) flighty steering. do you think an alignment will take care of it

Took care of mine although he set the caster to about 4.8 instead of going to 6-8 as recommended on here. He did say if I wanted more it was up to me but it drives great so far. Said drive it awhile and bring it back if I wanted more. The RC instructions say 4.6. My toe was off to and they adjusted it. I just didnt have the time this week to try it myself and it only took them about 40 minutes total.
Of course it cost me $55.

PS, I still have my stock 17" wheels and the 32" BFG's. Maybe that's why I didnt need the extra caster?

adding a little more caster will take care of it but you can only do this with a set of adjustable control arms. yes, you can do it with some cam bolts but i really wouldn't recommend it. also, you can add more caster yourself and do not need to use an alignment shop.
