A ladder bar won’t fix it. A 32 inch IC that’s what, 12 inches up isn’t that much better than what you have.
If you can’t get what you have to work, get a 4 link.
FWIW, you need WAY more bump in the shocks, probably need to slow the extension way down, put some air in the tires and see if you can use the shocks to control the hit AND keep the tire from bouncing back every time it gets hit.
What you are seeing is the tire getting hit, then bouncing back, then getting hit again and repeating.
Once you tame the back end down, you’ll probably need to go back up front and and tune it. Probably more travel, a bit slower to keep it from shocking the tires.
