No. If I turn my brake EPA up, I can lock up the front tires at WOT, skip the belt so hard the neighbor can hear it, and I've never lost a belt. However, my tunnels are still perfectly straight, I have a chassis brace installed, and the rest of my truck is in good shape.
Try tightening up the belt so it doesnt skip so much and do the WOT thing and see what happens.
