How to level out my Ford F150 1999?

I have a 99 Ford f150 xlt v6 2wd. It has kind of an east coast stance stock. I just want to drop the rear maybe 2 inches to kind of level it out with the front end. I don't want to comprise my hauling by removing a leaf spring. But is there a way I can move my leaf spring shackles to the underside of the rear end to accomplish this? Or how do I d it the right way. Again the front ensemble sits fine I just want to drop the rear about 2 inches.

Typically when you level a truck you are raising the front end but you can buy a 2 in shackle drop kit from a lot of websites. I don't think that would h your anything.
