You might have the up country suspension...... but that don't mean it isn't a sagged up country suspension......
I'm betting Freerider's leaf packs - being as they're likely alot newer than your suspension is - will provide more lift than you think.
As your jeep sits now, when you look down the line of the leaf pack with the shackle in front of you, and looking forward toward the front of the leaf pack, do you still have a decent arc in the leaf pack? Or is it nearly a flat line? Flat to nearly flat line = no lift, saggy leaf packs.
