I need the truth about UCA's

What do I need to correct my alignment yet not hinder performance (possibly improve)? I have 5100's and need the ucas to primarily correct alignment issues but my truck does see some offroading a half dozen times a yr or so. I searched the forums a bit and have seen multiple answers. While some say that the 5100's, due to mild travel, need nothing more than the ball-joint, others say that the ball joint sucks completely. What do you guys think would be best? Uniball or ball joint?

 

Since the 5100's you have only go to 2.5" of lift max, the Light Racing ball joint UCA's should be fine for you. Or the Camburg ones as well. Whichever your wallet leads you to.
