I run, design, build and produce a lot of hydro-assist parts for the TJ. It is a solution to a very specific set of problems and not a mod you do just because you can, it really needs to solve the problems.
Done correctly, hydro-assist is the supreme damper to protect your steering and trackbar and is 100% transparent. The only way you know it is there is you can turn your tires offroad as easily as you can in a parking lot.
