JKS J-Flex adjustable rear upper control arms for Jeep Wrangler JK provide a durable way to tune suspension geometry and improve off-road reliability. CNC-bent from DOM tubing, the fully adjustable arms feature rebuildable, greaseable forged ends and factory-style rubber bushings at the non-adjustable side. Sold in pairs, they use heavy-duty 1-1/4"-12 threads with hex-shaped weld-in bungs, jam nuts for secure tightening, and a powder-coated finish for lasting corrosion resistance.
