When our JKs are lifted 2.5 inches or higher, we need to address the track bars. The track bars, or Panhard rods, locate the front and rearends laterally. If the JK sits perfectly at stock height, then raising it causes the track bar to pull the axles toward one side. The front and rear bars are attached to opposite sides of the frame, so the frontend moves left and the rearend moves right. Adjustable track bars allow perfect adjustment and alignment, no matter what suspension height we end up with.
Teraflex’s front and rear Monster Track Bars are forged and, according to the company, are 230-percent stronger than the OE JK bars. They feature Clevite bushings, so there are absolutely no squeaks.
We want our JKs to drive straight. Ours does because we installed Teraflex Monster Track Bars.
