They work surprisingly well Dave. Both my Son's had these on bagged S10's, that is how we knew about them. Even raising or lowering the truck 4 inches each way had very little effect on them. Some have questioned that these might allow the rear axle to move sideways on turns, but the top bar prevents that from happening.

Both of their trucks had tons of miles using this setup and they had no problems at all. I was skeptical the first time I saw them too. For my Dodge it was the only suspension set up I had room for because of being bobbed so short in the back.
