5.5 RE springs sagging on right rear. Is there a better spring?

[tekeum]

Wow! That's a lot of sag. Are you loaded up pretty heqavy with armor, winch, bumpers, etc?
Is your 3" lift maybe a bit taller than 3"?
There's only a few ways to lift the rear of an XJ. Extra leafs, longer shackles, blocks or new leaf packs...

That is empty, stock bumpers I also run teraflex's longer shackles. Can I add some leafs from a stock spring pack to give it some lift? I don't want to go with blocks.
