They have a lifetime warranty. I had a heat shield put a hole in a bag on my last truck and they sent me a new one without making me send the old one back. I had Firestone on my 02' Ram many years ago and back then most bags went on the leaf springs and I kept breaking the bolts. All bags are now on the axle and not on the leaf springs which is a lot better. I think it was airbagit.com who had an ad in a Diesel Power years ago and I tried their bags and it was a disaster. Don't ever buy anything from them.
