If you have not had the TSB done and you add the AAL for trucks without the TSB you will be effectively adding a 2" lift to the rear.
Depending on where your truck sits right now, I am guessing that adding the AAL will give you back some rake. Probably something similar to stock where the rear is 1" higher than the front. I would say go for it. You can always take the AAL out if you are not happy with it. (It is not a very difficult job)
