A heavy duty, adjustable, front track bar designed as a factory style replacement for TJ/LJ, XJ, ZJ, and MJ applications. It directly mounts to the factory tapered track bar mount on the frame but requires the axle mount to be drilled to 9/16" for added strength. A recommended weld-on gusset is included for the axle side mount for reinforcement. The track bar offers improved rigidity and allows centering of the front axle when running a suspension lift. Fits 0-4" lifts.

  • Factory style replacement track bar for 0-4" of lift
  • 2.0" to 3.0" bump stop spacers will be required if the axle is pushed forward slightly from stock and an aftermarket diff cover is used. The larger diameter of the Synergy track bar and tie rod end will interfere with the diff cover if no bump stop spacer is used. We recommend cycling the suspension to full compression with the track bar installed to ensure no interference is occurring.
