It's time to replace airbags, Firestone or Air Lift

Good to hear the response from airlift. I have a newer airlift setup installed, and they haven't been without problems....I've had bolts bend and stretch. I blew an airbag line when a local body shop loosened the setup to do work on my rear axle, and forgot to tighten the bolts again....whole thing shifted under load and rubbed an air line against the exhaust. I did half the alcan without 1 bag. Luckily stabiloads helped immensely.

I don't regret my airlift setup, and I'll run it as long as it lasts.
