suspension lift question

Which type of front axle do you have? Regardless how you modify the ride height, you are going to have huge handling and tire wear problems. The only acceptable reason to replace or modify anything is to get the vehicle back to its design height. As a former suspension and alignment specialist and as a former instructor, I never got involved with any type of aftermarket height-altering schemes or the resulting legal ramifications. Lawyers and insurance investigators just love to find these types of modifications. I can describe a huge list of things that will result from changing the ride height. You might be able to address a couple of them, but you'll be changing the geometry that was carefully designed in at the factory. Ford has WAY more than their share of tire wear and handling problems right from the start. There's no need to compound the problems.
