Air lift air suspension kit 59501 will not work on your 2001 Ford F150 with a 5 inch lift. Generally, when installing air suspension on a lifted truck you would need a spacer kit to make up the difference of the lift. The only air suspension kits available for your truck use sleeve styles air springs. At this time there are no spacers available for sleeve style air springs. We checked with Firestone and Air Lift and they do not offer a heavier duty air suspension kit for your truck.
