The install is not difficult. Just time consuming in coming up with where you want to mount your air tank and manifold. I have autopilot v2 and it is very nice, you will not be disappointed. You will want to get all of those alignment pieces (camber kits, toe bolts, etc.) in order to get the alignment back to where it is supposed to be.
The first link below should be an install manual for the front airbags and the second link is the install manual for the rear bags. The manual is very helpful with plenty of pictures and descriptions to walk you through ever piece of the install.
