Three link front suspension does not bind as much as the four link that comes stock during maximum articulation. So in effect, the suspension is a little freer and theoretically will be easier on the bushings. One of the things that happens with long travel suspensions is that no matter whose bushings you use, they tend to need replacement often from crushing the sleeve into the outside of the bushing. Been there, done that. So if you are planning on lots of full travel, a three link can be an advantage. If you are mostly mall crawling, it is not necessary.
