I am in the process of installing these right now. They are easy to install on your core shock/struts. So far, the only hitch has been that the air line connection is a little higher and goes straight in the side versus the OEM unit which angles down by 45 degrees. As a result, I had to open the plastic fender liner and un-ziptie the air line to get an extra inch to reach the new air spring. I haven't finished yet, so hopefully no leaks!
