question on lift
I'm not really sure for your area, but I know when I was looking around before I decided to do it myself I was quoted anywhere from about 250 to about 450 depending on the size of the shop with the smaller family owned shops being the cheapest.
I have the springtech kit and have no complaints. I've done some mild offroading with it and it's held up great. You have nothing to be concerned with the spindles and UCA's, they are beasts compared to the stock parts!
I love mine but the Springtech is a very good option too. Gets the job done and is cheaper. If you plan on going higher but don't want a body lift for some reason, the fabtech will let you get aftermarket UCAs and spacers/lift coils instead of the Springtech which uses UCA and coils to get to the 6.5". But that is a moot point if you plan on stopping lifting after
