Got the new Rancho shocks installed today, with only minor setbacks. Wow, what a difference.
I had the factory shocks on before, with 125000km on them. I experienced a lot of body roll, and bumps were extremely studdery. The Rancho's have greatly reduced body roll in the corners, and the Jeep no longer studders over bumps of any kind. My passenger (buddy who helped) could feel the difference as soon as we pulled out of the driveway. This little 2 door feels like it's on rails now. Very, very responsive. I am extremely happy with this purchase so far, however only time will tell if I like them better than the Bilsteins on the truck (I have 100km on the Rancho's right now).
I will note that for installation, I left the dust guards off of the front shocks (there were rubber), and cut them off the rears (plastic - exacto knife worked great). I do tend to traverse watery areas, so I did this to avoid trapping water in and around the shock assembly.
