            Just right

            This is a good lift if you want to get some clearance over stock height with a more aggressive look. The rear still sets higher than the front so it doesn't really “level” the truck if thats is what you want. Took about a day to install with 1 person and impact wrench and a good assortment of tools. The suspension angles (ball joints ect..) are with in stock specs and rides better than 2 inch front level I had before.
