Your answer will depend on what you are doing with it. True link suspensions are used in a lot of applications but the are built differently. If you are going for long travel and jumps then the above kit from giant would be the way to go. Triangulated 4 link if I remember correctly, they may offer a 3 link also. If you are going rocks and such you could scratch built that yourself from tube, no need for the massive lowers that a prerunner uses. Pirate4x4 has a few calculations you should be looking for in building a link suspension. A 5 link or 4 link with track bar is good mainly for the street, the track bar is the limiting factor in the suspension travel.
