Enhance your Wrangler TJ, LJ, or Cherokee XJ Jeep with JKS J-Flex adjustable front upper Control Arms. CNC-bent from DOM tubing for proper tire, frame and axle mount clearance, these front upper control arms feature forged flex ends that are adjustable. The design increases reliability and allows you to fine tune arm length. The ends are also fully rebuildable and greaseable. With heavy duty 1/4"-12 threads and hex shaped weld-in threaded bung, tightening of the included jam nuts is super easy and secure. At the non-adjustable end, the bolt-on mount is boxed for increased strength. Arms are powder-coated for a long-lasting finish. Sold in pairs.
