So i didn't do the SAS on this truck and i'm not sure what's the PO did here to install the spring hanger kit. after a couple wheeling trips, it looks liek the OE frame cross member is starting to crack.

I bet if you look more you'll see more cracks in the frame. I brace mine all the way from the body mount under the door to the very front taking out the front body mount I'll try to get some pics, I've went as far as the whole front bracing too plus inside the frame to the motor mount.
