They are super easy to install. They come deflated and you just jack the car up so the spring is spread apart, roll the airbag up slightly and feed it into the inside of the spring, unroll the deflated bag, put the nipple through the top center hole in the spring. Attach the air line and inflate. They're nice because they are infinitely adjustable. You can run between 10-100 psi in these. I've used them in the past in other vehicles. Air Lift has been around for a long long time. Hauling 4 adults around? Air them up, when you're done you can deflate and set the firmness where you want
