These Motobilt Jeep lower front control arm mounts will fit a Jeep TJ, LJ, ZJ or an XJ. The mounts are CNC cut out of 1/4 inch thick P and O steel. The factory control arms on the Jeep TJ, LJ, ZJ, XJ are notorious for failing as they are made of very thin metal. They will either tear off from the axle or bend/break. The solution is to cut the old mounts off and weld on these HD Motobilt front lower control arm mounts. These mounts will also fit Rubicon models!
