I'm not entirely sure. The BodyArmor 4x4 ones seem pretty strong since they are bolted to the frame. But if you aren't dragging it through the rocks, I wouldn't be worried about it at all.
I like the ones I have, but after the body lift, these Mopar ones look more appealing since they would have no crack.
The only thing I can see being annoying is your kids getting in and out of the Jeep now. I can't imagine a 5" lifted Jeep on 35s with a ~2" higher side steps is easy to get into.
