dont feel bad dude, when i installed my first 4-link i called sd.com (where i bought the link from) and asked Jason. he giggled and said, "im sure there is a touque spec for it, but i dont know, really damned tight." i usually use a pretty beefy breaker bar and go to town on it.

I just tighten them until everythings squeezed together good, and I feel comfortable with how it feels.. dunno how to explain it, it's just like tightening anything else.. kinda what Eric said pretty much lol.

Other than motor and transmission bolts I tighten that shit down as much as my pipe cleaners will allow.
