Air Lift

Just woundering if anyone is running the Air-Lift coil helppers in the front of their Jeep. They are a polyurethane air bag that goes inside of the coil replacing the bump stop. I just bought some for the front for use in the sand dunes because my rustys springs are way to soft, now I can adjust the spring rate. I can have anywhere from 10 to 50 pounds in them, and when you fill them up they extend up and outward to fill up the coil spring. I should be getting them friday or monday UPS, wanted to know what you guys thought of them. When I instal them I will let you know how they work!

The only time I have used a similar product was in my old Ford, and I used it only in the winter while the plow was attached to the front.
