Brand new bouncy shocks

Hey all--

Had my '94 YJ for 15 years. Was starting to get to where I could feel every pebble or penny I rolled over so I changed my shocks out (something I don't think had ever been done--we sure hadn't) for a set of Rancho RS5000s. I do a *little* off-roading, but most of the travel is on pavement and was told the RS5K was a good all-purpose set.
The issue: now, if I go over the slightest bump, I get a 2x-3x bounce. Also, if I hit a bump or a dip, i can hear a "thump" and the bump of whatever I ran over, no matter how small. Doesn't seem to be any shock absorption going on at all. I hate to say it, but it seems even worse than the stocks I pulled out.
There's no sway at all when I turn a corner. Just a lack of absorption and excessive bounce. Any ideas?

Get on your bumper, then bounce up and down, jump off. If you car/Yj bounces any more than one up Maybe slightly down a bit depending on your weight then stops.

Your shocks are bad.

its time to rebuild your bushings. pull your springs off and rework everything until the shackle and spring-eye move freely. you should be able to torque them to factory specs and still move them by hand.

Dumb question but did you install them correctly?
I don't think they can go upside down anymore but if you dented them on installation you could have messed them up... or they are bad out of the box. It happens.
