JKS Manufacturing J-Flex Adjustable Rear Upper Control Arms for 2007-2018 Jeep Wrangler JK (Pair) - JKS1665

Fits all 2007-2018 Jeep Wrangler JK and Wrangler JK Unlimited models, including Rubicon, Sahara, Sport, and X trims.

Correct your suspension geometry and fine-tune your pinion angle with JKS Manufacturing J-Flex adjustable rear upper control arms. Engineered to enhance off-road reliability and articulation, these arms are CNC-bent from heavy-duty DOM tubing to provide necessary clearance for the tire, frame, and axle mounts during extreme articulation. The fully adjustable design allows for precise alignment settings on lifted vehicles, while the included jam nuts and hex-shaped weld-in bungs ensure a secure, simplified installation.

These arms utilize a hybrid approach to performance and comfort: one end features a forged, fully rebuildable, and greaseable flex joint for maximum off-road movement, while the non-adjustable end uses factory-style rubber bushings to maintain a quiet, vibration-free ride on the street. The entire assembly is finished in a durable powder coating to resist corrosion and trail debris.
