Stock UCAs will be fine.

Stock LCA's you might want to reconsider, but I've seen it work fine.

I've got the Rusty's 3" lift w/1.5" spacer up front, stock UCA's, adjustable LCA's, and it works great with no problems.

I meant i already have LCA for rusty's 4.5" lift installed.

Ah...

Yeah, it'll be cool then.

I just wanted to make sure. I'd rather save the money for my 4x4 swap. I was looking at these

Those are kinda nice...if you have the extra cash, I'd go for it.

It's not gonna break anything though to try your existing arms and see if you need to change them though.

Do you think it would be worth paying $200 shipped for the fixed control arms? If i keep my current setup am i going to have any alignment issues if i dont get the other control arms?

Any time you change the hieght of your jeep you are changing the steering geometry and therefor it will no longer be alligned properly, regaurdless of the control arms. As far as getting new UCA's, it all comes down to what your pinion angle is with your stock upper's. If its not to bad, say within 3 degrees or so than dont worry about it. I know when i went to 6 inches i had to get adjustable uppers, but that was mostly because of the drop bracket kit i put in. I would say try the stock uppers first and see how it looks.

pinion angle means jack sh1t...

you MUST get caster to -6*/-7* to get it to drive decent on the street.

if you can't do that, you can redrill the stock control arms at the axle end to get a little more length out of them (welding washers on around the holes is a must if you plan to keep it that way) but otherwist you'll need new longer or adjustible uppers.

you have your choice of good pinion angle or good caster angle, and good caster angle is more important

I would just do drops brackets cuz then it will eliminate any caster angles and should put it back to stock angles
