I am going to add a suspension lift to my '00 F250 superdty crew 4 x 4. I'm looking at the Skyjacker Z-link 6" which converts the front leaf to a coil around system. I'm trying to improve the ride quality over standard lifts. Air bag system by kelderman, which would be nice, is 5,000 just too much dough. Anyone have an opion, I would like to hear it.
