installed the new rear rancho shocks that are none way adjustable and holy cow why a difference. Expedition had 95k miles on stocks and the difference from1-9 is insane. 9 hard as rock very little bounce and very stiff truck like ride perfect for when I two my boat. Right now I have it on 5 and much better ride. Truck feels flatter thru turns and bump are enjoyable. Gona do the fronts next for sure Sent from my iPhone using Tapatalk
