What would be the best steering correction to do first? I've got 4.5" of lift and stock control arms all the way around. The handling isn't bad now, just a little twitchy. I noticed ore has a flip kit out now for the price of an adjustable set of lca's.

 

If you complaint is twitchy then control arms are probably the fix. You can add back some of the castor and with that much lift you will likely need a front driveshaft at some point. Then the arms are usful in makeing sure you have a good pinon angles.

 

control arms will allow you to add a bit more caster and that will help to get rid of the "twitchy" feel that you have in your steering. if you can afford to get upper and lower arms all the way around, you will also be able to reposition your axles under your jeep and that will help things out as well. the trackbar relocation/draglink flip would be real nice to have as well and with everything together, you would have a much better handling jeep.
