I just did my 1.5 Zone this weekend. It takes ALL of 5 hrs. Not a real hard install but time consuming taking off all the front stuff like bumpers, grill, headlights, fogs, light bars, all fan shroud brackets and all the plastic pieces over and under the motor. Then the rear you gotta trim the bumper, loosen and spin your exhaust tips to fill the holes, and put spacers above your hitch. There’s the bulk of your time. Lift itself isn’t that bad. I did it myself with help from a buddy. We’ve done a few regular suspension lifts over the years. If I had to charge to do one....I wouldn’t do it for under 400 bucks would be my price, and I have no shop or over head. So some of those prices aren’t too too ridiculous honestly.
