Let me start off saying that I'm new to jeeping. I just bought a 2006 wrangler X with a 4 inch Teraflex lift, and 35 inch tires. The lift still has the stock rear control arms, both upper and lower. I was informed of this prior to purchasing the jeep. My first question is this: What will I gain with after market control arms in the rear? Second, what after market rear control arms would you recommend? What do adjustable control arms get me? How do I know how long to adjust them? Any help is appreciated.
