Question about struts

Hey guys, I know there are a bunch of threads about upgrading to Eibach springs and KYB shocks, but I have a quick question about installing them. I am gonna go with the Pro Kit/AGX combo through Club 3G, but wanted to know if they will come pre-assembled, or if I will have to use a spring compressor to put them togeather. Also, the rears on our cars are struts 2 right?

yse there both struts, yes you need a spring compressor, also need an airung to take off nut. As for being pre assembled, i doubt it. I can do all four in less than an hr. its very easy. So just ask me if oyu need help.
