I have a set of rear Koni 1722 shocks I took off of my car. When I push the rod in the shocks it stays. I'm used to gas shocks pushing the rod back out. I'm guessing they are hydraulic or are they both bad?

Thanks Chris.

They dampen - they don't push back out like a gas shock.

As you articulate the rod, and depending upon where you have adjusted them, you should feel resistance.
