the lowers are real simple to change out and you don't even have to jack up your jeep or remove your tires. just follow the caster setting part of this write-up and you should be good to go:

as you can guess, the fronts will help you to add more positive caster. the rears won't do much for you other than offer less bind in your flex.

What will the lower control arms change to how the jeep drives?
Your caster will be lower after the lift, which affects the way your jeep handles. Caster is not adjustable with the stock (factory) control arms, so new adjustable ca's are used to bring the handling back to a more acceptable level. Here is the blurb on caster from the faq's...

Q: What is Caster? How much do I need?
A: Caster is the angle upon which your front axle sits at in order to help keep your Jeep driving straight. Positive caster, which is what you want, will cause your axle to sit in a way that your pinion shaft will be dipping ever so slightly towards the ground. Too little or even negative caster angle can cause your Jeep to wander and feel 'flighty' or 'darty' as I've heard some people call it. From the factory, your JK will have +4.2° of caster and if you lift it and install larger tires, you will need to increase this amount to help compensate for the modifications. At 3"-4" of lift, I have found that +6°~8° of caster will do wonders to help improve the handling of your Jeep JK Wrangler.
