What is it?

I have a 1989 5.0 mustang I am trying to get back on the road after it has sat for many years. Change all the fluids replace what looks worn out filters the works so I am looking at the rear suspension and don't know what this part is so I can look for a new one or at least know what it does. I hate to look like a noob for asking this question but if you look for suspension parts which there is about a million or more out there I have not come across one of these to even know the name of it. It looks to be a factory part, there is one on each side. Here is a picture, caution there may have been spiders killed to take this photo

That would be the quadshock. Its sometimes not needed, just depends on your car. Definitly can drive without it, but might have some wheel hop. Put poly bushings and just about guaranteed you wont need them.

Thanks! I think they even miss label this part lol. Lists as a stabilizer but is more of a damper than a stabilizer. I don't see where it would do much good unless the control arms are sloppy or the mounts where spot welded out of place. My mustang is an automatic so I am going to try some better control arms and leave em off and see how it does. I already have the weld in sub frame connectors on the way.
