2000 Mitsubishi eclipse RS. What do I need to buy to fix my suspension?

I have a 2000 eclipse and my suspension is bad. My car bounces a lot over every bump. I know it's my shocks that are bad. I went online to buy some but I keep finding struts and single shocks. I'm confused on what to get because my car has springs in its suspension and I noticed that all the struts ive seen online don't. I just need help finding what to buy basically.
