I searched, couldn't really find a good answer. I have been searching on ebay for a Leveling kit and some of the places are stating that some kits won't work with an FX4 or Heritage. Then some will state that it won't fit the FX4 specifically. What is the differences between the f-150's?
I am looking to get a 2.5" level kit. Thanks, and I apologize if i am

 

The 2004 Heritage Edition looks just like the 97-03 F-150's and has the same suspension. The FX4 and other 2004's look like the 2005 through 2008 F-150's. If you have a Heritage edition 4x4, you don't need a leveling kit. The ride height is adjustable via the preload on the torsion bars. If you have a Heritage Edition 4x2, you need a set of coilspring spacers for a 97-03 F-150 4x2. If you have a 2004 FX4, any leveling kit for the 2004-2008 F-150 4x4's will work.
