What kind of shocks should I get for my 2-link?

Hey guys whats up? I've had bags for on my fullsize for almost two years and have never had a problem until a couple of days ago I took my truck to the shop to get the rearend narrowed 2 in from each side and noticed that my left shock was broken in half (like it has a huge hole in it!). I have an Ekstensive 2-Link with an Erratic Trends C-notch. I noticed that my panhard bar was the reason for smashing my shock. My shocks are still in the factory location. What should I do??? thanks fellas!
