I went from a 2013 to a 2017, my 5er already had taller profile tires (215/85r16 vs the factory 225/75r15) and the springs mounted to the lowest position on the hangers to level it out with my ‘13, the ‘17 being taller was a problem that was going to need some attention - I did a little research and found out you can swap over the rear lift blocks from a 2011-2016 F250 that are only 2” tall to replace the factory 3 3/4” lift blocks. I spent the 50$ at the dealer for the blocks and new u-bolts and voila, truck is now 2” lower out back. Still has a little rake and looks like I have a leveling kit, yet it’s lower.
Mine is on the left, next to it is my fathers and his is stock.
Don’t mind the mud, the campground at Watkins Glenn last weekend was a mess!
