Includes full length adjustable Panhard Bar and 2″ lowering blocks. Incorporating the Panhard Bar mount into the lowering block allows for the use of a longer bar and corrects the bar geometry to minimize lateral axle movement and allowing ht axle to be centered at a lowered ride height. This also lower the roll center reducing body roll. The patented R-Joint rod ends combine the best qualities of low friction movement, lateral stability, full range articulation, and quiet operation into one special bearing that is as home on the street as it is on the racetrack!
