You can use these strut assemblies, though you would be better off removing your front leveling spacer and just using the higher ride heights provided by the Bilstein 5100s. If you have a rear block installed, then you could get away with using Bilstein's 5100 rear shock for the 4WD 2004-2008 F150s. If you don't have a rear block, then you can use Bilstein's 5100 rear shock for RWD/2WD 2004-2008 F150s.
