Ride in my Lariat Screw is perfect althought the headlights need adjustment.

Does not void warranty.

If you want to put larger wheels on you will have equal clearance on front & back. Levels the truck (which I prefer on a true 4x4).

Advise you find a shop to do the install. Should cost $150 max.
