What 3.5" lift are you getting? You do know that most kits out there yield way more than what is advertised, right? With 4" of lift or more, your caster will be off enough to warrant a correction and you will NEED at bare minimum, adjustable front lower arms to do that. Also, if you have a 2-door, your rear drive shaft will be sitting at a severe enough angle that you will NEED to replace your rear drive shaft sooner than later as well. To do that, you will NEED adjustable rear upper arms to set your pinion angle.
