Everything JKS manufactures is high quality. JKS Control Arms utilize greaseable brass bearings for smooth operation and longevity. Fine pitch adjustment threads make it easy to "tune" the JK with over 3 inches of range. The Trailrunner now has a 97.5-inch wheelbase. New OE rubber bushings are used to isolate road noise and vibrations without over-stressing the mounting brackets. JKS track bars are strong and adjustable, although you need a minimum of 3 inches of lift for them to work (they're longer than stock at their fully collapsed length). They utilize OE bushings for reliability and quiet operation. Have you driven a modified JK that had a completely silent suspension? You can if the JK is equipped with JKS control arms and track bars. The bracket shown here is a strong JKS rear trackbar bracket, which we didn't use as we needed to raise the rear trackbar.
