A couple weeks ago on Xtreme 4x4, Ian took a 4x4 out and tested it with a suspension expert, then had a suspension guy revalve the shocks. The difference was night and day. You could see how stiff the valving was just watching it drive past. After the revalve, you could see how much smoother the ride was. Less shock being transmitted to the body. Also, this allowed the suspension do its job. It looks like it would be worth the time to talk to a shock company and see what they recomend. Just because they "fit", doesn't mean there the right ones.
