I got my Flippac in December and it came with a 3/4" aluminum tube that encased the torsion bar. The bar actually broke in April and FRP replaced it under warranty. They paid for some of my gas money to come down to Riverside from the Bay Area. The broken torsion bar poked a hole in the thin aluminum tubing when it snapped, but kept everything intact. It possibly saved my truck & camper from getting scratched/ dented by the snapped torsion bar. The tubing gives it a finished look as well.
I'll try to post pics tomorrow.
