I have looked around and didn't find exactly what I was looking for...

I am looking at getting a Superlift AAL kit to have more towing capacity along with the added lift that it will give. I know that I have to crank the t-bars for now (I don't have the time to try and find a front axle or the time to install one if I did find one) and was wondering how many of you guys that have done a 1.5" to 2" suspension lift got new front control arms? Are the absolutely necessary for realignment? Maybe that is a stupid question, but I would like to go into this knowing more about what I am getting into before it is too late. Any input is greatly appreciated!
