I have a 2002 Jeep Wrangler Sport and installed a 2" Pro Comp suspension lift kit. The lift came with no additional control arms or suspensions components of that sort to accommodate the lift. I did not think that those parts would be necessary considering it is only a 2" lift, however, I have pinion issues (that I am going to fix soon with adjustable control arms) and alignment issues. I am curious about what other suspension components I should upgrade to ensure a properly functioning jeep. So what else should I upgrade from stock? Front and rear track bars?
