How about a shackle reverse? I removed the rear spring frame mount and used another front mount from the rear spring it makes the shackel point down instead of up.Its good for about 4+. You may have to drop your transmission crossmember slightly to match your new pinion angle, but that is a plus for driveline life anyway with a lift. I particularly like this for broncos and short beds, reduces driveshaft working angle. I also articulates well because the springs are not so stiff. And it's cheap also.
