Title: Airliftt rear spring air kit.
Review: They advertise 1 hour installation, it took me four hours. It involved putting a jack between the frame and axel to make room to fit the bags without distorting them. One u-bolt was instlled upsidedown to avoid interference with brake line.Other than a little hassle with installation they're great. Only 15lbs pressure brings me back to level with my travel trailer.Amazon price beat all other advertised prices, and shipping was free.
