I spoke with a tech over at Firestone and they said the # F35FV will not fit on a vehicle with 50mm between the axle and jounce, unfortunately.

With that being said, we do also have the Air Lift LoadLifter 5000 # AL23FJ. This is rated up to 5,000 pounds as well and will also fit the FX4 models of Ford trucks. The only real difference between them is the bags. Firestone uses heavier duty 4 ply, whereas the Air Lift bags use 2 ply. Both do also have a lifetime warranty on the bags, though.
