We just finished installing a 2" Top Gun Customz Leveling Lift Kit on a 2009 Ford F150 4x4 King Ranch Edition. With this kit, you simply unbolt the strut from the vehicle, install the steel spacers on top of the strut and bolt everything back up. Ride quality is unchanged.
You're born, you take S**t. You get out in the world, you take more S**t. You climb a little higher, you take less S**t. Till one day you're up in the rarefied atmosphere and you've forgotten what S**t even looks like. Welcome to the layer cake son. ~Eddie Temple
