I recently had leafs added to my X because of sagging in the rear...about 1" or so....if you go to a local spring shop they should be able to add a leaf (or two) without raising the hieght too much above stock....just make sure you get them to re-arc the whole leaf pack to give you the desired hieght you want....I had a leaf added to each side and the packs re-acred and got abotu 1 1/2" back, up to stock hieght and it rides perfect again....
