I just replied in your shock thread, No doubt the question on shocks came because you are considering AEV's lift.

Heres my opinion since your asking.

The cost of the AEV lift dosent make sense with what you actually get. It wont twist like Currie, Rock Krawler, Teraflex, etc.

Its not made to. Its made to keep the stock ride but make the truck taller to deal with larger tires.

This means no new control arms. Which, if you wheel, are as important as the springs themselves.

You need to more research before you spend the coin this would require. I know people who have taken their AEV lifts off, and changed to RK or TF.

You dont want to do the lift twice.
