Either the wrong rear springs or the lift was an AAL and the rear has just gone flat.

Could be flat leaf springs as said above.
hopefully it's not a block or shackle lift paired with flat leaves.

It looks to have a shackle lift a d the leaf springs looks pretty darn flat to me. What's the cons of having flat leafs with shackle lift?
these are the best photos I have rn of them. Will take better ones when I'm off work

Here is a pic of a new 5.5" leaf spring to compare with. I can assume your lift has seen better days.

Trying to get mine like that ☺️ did you extend the brake line? If so what did you end up using? Was thinking of just adding a block 🤢 until I end up buying new springs

Rubicon Express extended rear brake line for 5.5" lift. Approx. $50.00. You can fine no name brands on Amazon for $35.00 but I am assuming that with your XJ having a lift already, it may have an extended brake line already.

Don't do the blocks, just wait until you can replace the springs with new

**** UPDATE ****
Found the problem child it is indeed the leaf springs. Went over some speed bumps you know going faster than I shouldn't have and I found that the rear springs are now negative cambered. Will be replacing them when I can afford it. Thank you everybody for you guys a suggestions
