The 851's are in my back yard, have been installed but still have the OME tag on them. The 864's are on my rig right now and will be avail. in about a week or so. I currently have the slee 6" springs up front with and ARB and warn M12K with a empty rear/no bumper and the rig sits pretty level with the 864's. I am upgrading to slee 6" rears, building a bumper, drawers, rack, spare tire carrier so the rear is about to start sagging. Located in MD, $225 +the ride for both pairs.
