JKS Rear Adjustable UCA

Your Jeep Wrangler JL will benefit from JKS J-Flex adjustable rear upper control arms. They adjust for proper geometry while increasing driving comfort on the road. J-Flex arms are built from heavy duty 2" OD x.250-wall DOM tubing and CNC bent for additional clearance. At the axle mount, J-Flex arms feature premium OE style rubber bushings to absorb noise and reduce vibrations for a comfortable, quiet ride and maintenance-free operation. At the frame-side mount, J-Flex arms incorporate a unique hex-shaped threaded bung for easy adjustment of the forged flex end and 1-1/4"-12 threads jam nut Flex end design allows for 30-degrees of misalignment (15 in either direction) for impressive articulation and are greaseable to ensure long bushing life. When the time comes, JKS flex ends are rebuildable. As with all JKS control arms, these J-Flex lower control arms come finished in a durable gloss black powder coat finish and are backed by JKS'™s limited lifetime warranty. Sold in pairs.

  • High strength 1.5" x.120" wall DOM construction.
  • Adjustable design utilizes a forged flex joint and jam nut.
  • Specially formed for proper tire, frame, and axle clearance.
