two links will always work fine for people who dont investigate. There are always "seat of the pants" guys who use their butt dynos for measuring everything automotive. Other people will use them as long as people say "it worked for me".
I'm not saying the planet is going to collapse on itself if you use a two link. But the reason people sell them is because you can charge a lot for something easy to build and easy to install, its a retail win win. People like them because it doesnt really take any skill to build yourself or install in a 1/2 hour, and you dont have to move the gas tank. Really has nothing to do with how they work, looking at every picture of lifted trucks you can see how painful the pinion angles will be on u joints. But u joints are cheap right?
What I dont get is how people will agonize for months on the exact shade of color they want for their trucks, and spend thousands on chrome or billet wheels, and use a 1/2 hour to install their rear suspension.
The ultra long, flexible, 67-72 Chevy truck trailing arm suspension has absolutely nothing in common with the 1/4 wall box tubing people use for two links. There is no factory application that mimics what is used by minitruckers, and to say you put the same thought into the design as the tens of engineers who spend thousands of hours designing that truck suspension (that was outmoded in 1972 BTW)is really an insult to all their hard work.
If anyone took the time to read a suspension book, or a physics book, you would understand why you shouldnt use two links. But no one will, its easier to say "it worked for me" and never know.
Do whatever you want, locate your rear end with toasted marshmallows for all it matters to me. But easy doesnt mean better, some things are hard because they are worth it. Suspension design is one of those things to me.
