CB Engineering 2005 - 2010 Jeep Grand Cherokee and Commander Rear Track-Bar. This will replace the weak stock rear track-bar. The track bar is made of thin steel tubing with rubber bushings that don't allow much articulation or adjustability. Our track-bars are made from 3/16" wall DOM tubing that will last a lifetime and will never break. On the body mount side of our track-bar comes with polyurethane bushings and custom stainless steel sleeves to work with the unique width of the WK and XK mounts and metric bolts. Zerk fittings are standard at each joint. On the axle mount side we use 2.0 Johnny Joints for more adjustment than stock the track bar. Our adjustable track bar allows for 1.25 inches of fine tuning of the track-bar length to center the axle under the vehicle when using larger lifts. Our track-bars are shipped bare steel for coating by the customer. These are designed for 0 to 3" or 4 to 6" of lift with Superlift Brackets. 7" - 8" of lift a longer track bar needs to be used.
