The tires are 235/85R16. That makes them 32 inches which is 12% bigger than stock. If you have a 3.73 diff this size tire will perform as if you have the 3.31 diff. I am going to see if the dealer will reflash so the van thinks the diff is 3.31.
The bug shield is the OEM Ford part.
The price on the lift is $1700 the labor is up to you, from what I saw it is an all day project.
