Q: Should I buy this alone or with the other rear links?

It works on its own, but we recommend running the full rear suite for the best result: the adjustable camber and toe arms, the trailing arm, the upper fore traction arm, and the adjustable sway bar. Fitting them together means a single install and alignment, with a rear end where every link is billet and located rather than a mix. The complete suspension package bundles all of it if you want the whole thing at once.
