For anyone wondering if you need extra gear to move. Listen. All you need are these 2.5" washers to keep your truck level. I have a 2019 f250 Lasso 6.2 Gasser and it has worked flawlessly with these lifting discs. I MAY use longer shocks because as you can see in the photo the shock naturally lengthens an additional 2.5 inches. The ride quality hasn't changed at all. Someone installed it for me because I was too busy, it was $250 out the door.
