Ok, now that you've decided that part.
Have you considered the cost...? It's not a cheap decision by any means and requires assistance to install if not knowledgeable.
1) Hydro Rams & Connecting Parts = $200-$220.00
2) Ram Mounting Kit = $100.00
3) Clevis Kit = $100.00
4) Orbital (Steering Control Valve) = $275
5) Above Mounting Kit = $20-$25.00
6) Steering Columns = $50-$60.00
7) Tie Rod Kit = $130-$140.00
8) Lines & Fittings = $20-$25.00
Total Investment without labor = $895.00-$945.00
Pretty BIG investment with NEW parts. People have done it for less with the abilities to improvise and aquire used parts.
No, I have never install one. I do understand how and why they work so damn well. I might have forgotten a fluid cooler too, I've seen some systems with those installed.
A "Ram Assist" system can be had with all needed compenents
