JKS J-Flex adjustable rear lower control arms for 2018–2021 Jeep Wrangler JL. These arms allow length adjustment to correct alignment and improve rear driving comfort, constructed from 2" OD x .250-wall DOM tubing for increased strength. At the axle the arms use premium OE-style rubber bushings to isolate noise and vibration; the frame-side hex-threaded bung and greaseable forged flex end enable easy adjustment, articulation and rebuildability.
