So heres the deal, I drive my XJ very fast on very rough roads daily during hunting season, and I plan on putting a long arm on it in the next week or two (I also wheel it during the rest of the year). It is fairly well built already with gears and lockers on both ends, lift, 35's etc. My question is having never had a long arm jeep or even ridden in one, do I go three or four link, and what joints should be on each end so that I have good flex and also can fly down crappy roads without feeling like every bump is going to either tear the diff out or break something? Also is a Y link or actual four link going to ride and handle better?
