The LJ 5.5" Rock Runner System is perfect for those looking to get the most out of your Wrangler. The rear axle is pushed back 4" putting the wheel base at 106" making it great for just about all off-road conditions as well as street use. The high clearance lower control arms improve cross over angles and off-road ability.
