How hard is it to install all these parts. I have all the tools and want to do it myself, but don't want to mess the car up.

 

Its not a difficult DIY job if you have the right tools. Although not required, having an impact wrench makes it a lot easier. A spring compressor, torque wrench, floor jack and jack stands are mandatory. Read the TacoBill "how-to's" - he has one for springs and dampers and another for the PHB. The PHB install is a no brainer, don't even need a guide except for the torque specs and how to do the adjustment. The rear springs and dampers are straight forward. The Fronts a little more difficult. It took me several hrs, over two days because I didn't have all the right tools and had to make a trip to Sears.You should check the pinion angle afterwards, it will probably be fine but its worth a check.

Also, if you are not aware: you should get the car aligned afterwards. You may need camber bolts or other type of camber adjustment if drop causes too much negative camber (according to Ford spec).Personally I like a lot of camber, the front end sticks better and I'll trade that for the slight increase in tire wear. The drop will cause the toe to change, so you need the alignment regardlessof camber changes.
