Wrangler JK 2007-2018 Jeep 4WD - Adjustable Rear Upper Control Arms by JKS

JKS1665 J-Flex Adjustable Rear Upper Control Arms are designed to strengthen and fine-tune the rear suspension of Jeep Wrangler JK models. Engineered for lifted applications and aggressive trail use, these heavy-duty control arms allow precise adjustment of rear axle positioning and pinion angle to optimize suspension geometry and driveline alignment.

Each arm is CNC-formed from stout DOM tubing to provide proper tire, frame, and axle mount clearance while delivering significantly greater strength than factory components. The fully adjustable design utilizes a forged flex end with heavy-duty threads and a hex-shaped weld-in bung, making length adjustments simple and secure. The flex joint is fully rebuildable and greaseable, ensuring long-term serviceability and reliable articulation.

At the fixed end, premium factory-style rubber bushings provide quiet, maintenance-free operation by isolating noise and vibration. Finished in a durable powder coat for corrosion resistance and long-lasting protection, these rear upper control arms are sold in pairs and built to deliver dependable performance both on the road and off the beaten path.
