Correct front axle centering on your lifted Jeep Wrangler TJ or LJ by installing a JKS Adjustable Track Bar. For use with Jeeps with a 4" plus lift, JKS front track bars feature rubber and poly bushings to isolate noise and vibration. CNC bent DOM tubing is powder coated and zinc coated. Vehicles with Dana 30 axle, aftermarket diff. cover and less than 3.0 in. lift may require bump stop adjustment to prevent interference.
