I've got an Astro Van Steering box that I just got back from West Texas Offroad having it completely rebuilt and drilled & tapped for hydro assist. It'll come with the hydro hoses and the 1.75" diameter 8" stroke hydro ram. The ram has been internally limited to 4.5" for my application, but that can be changed if you pull it apart. I used this setup for one ride at URE and now I'm going tons. Below is the picture of all the pieces before I installed it. The only pieces you won't get are the tabs welded to my diff and tie rod. The power steering pump also isn't included. It'll obviously have a little dirt on it now, but that should be expected. The heims will come with the ram.
