The rear of our Dodge already had a factory block, and we did not order new rear leaf springs (dumb idea), so we opted for a simple add-a-leaf to get an extra couple inches out of the rear to level it out with the front 4-inch lift. We've had good luck in the past with putting add-a-leafs in newer truck spring packs so we didn't think it'd be a big deal. Big mistake! These rough rider rear leaves that came on the back of old Dodges are already terrible, and adding the extra leaf made it even worse! Either replace the rear leaf spring of your Dodge, or ditch the factory block for a longer block.
