Your truck has fords I-beam from end. You can go up to 2" or so with spacers or lift coils before you need a proper lift kit (anymore than 2" and you'll have issues aligning it). Companies like skyjacker and rough country make 4-6" lift kits for your truck. They run in the 4-700 dollar range (been a while since I looked though). That's just for the kit, which includes drop brackets, lift coils, etc. Install would be a separate cost. A proper suspension lift causes no added wear to your suspension. It maintains factory angles and ride. Now, bigger tires and off-roading are another story. Lol.
You can do a body lift as well. A 3" body lift will run you about 200 bucks (again, without instal)
You depending on how big of a tire you want to run, you may need to regear.
You pretty much hit the nail on the head; all you need is money. Lol.
