I have a 4.5 lift in my xj i currently have Rough Country lower control arms, that have completely ruined bushings after only 3K miles. The BDS adjustable track bar seems to be high quality so I'm considering them for my control arms too (upper and lower). They have arms with flex and standard ends, which would be best for a daily driver with very little off road use? I believe I need to adjust my pinion angle because with my front drive shaft in, I have a vibration that I don't have without it
