I didn't know this until I started reading around the interwebs and Air Lift's site, but yes true to their warranty they do in fact replace their air bags with no fuss. I called their (800) 248-0892 line and had a short conversation w/ one of their reps. They're sending me a new bag + all lines at no charge to me. No RMA nonsense. I believe it's because I also registered my product (Air lift 1000) when I bought it, so they had a record of my purchase, so don't neglect doing that when you buy your Air Lift stuff.
