JKS Manufacturing J-Flex Front Adjustable Upper Control Arms for 2007-2018 Jeep Wrangler JK (JKS1615)

Fits 2007-2018 Jeep Wrangler and Wrangler JK models including Rubicon, Sahara, Sport, and X (2-Door and 4-Door Unlimited).

Improve your JK's off-road performance and suspension geometry with JKS J-Flex adjustable front upper control arms. These arms are CNC-bent from high-strength DOM tubing to provide essential clearance for tires, frame rails, and axle mounts during extreme articulation. The adjustable design features forged flex ends that allow you to fine-tune caster and pinion angles, which is critical for maintaining proper handling and drivetrain alignment after installing a suspension lift.

Designed for durability in harsh environments, J-Flex ends are fully rebuildable and greaseable. The non-adjustable end features a "boxed" mount for superior structural integrity, while the entire assembly is finished in a durable black powder coat to resist corrosion. These arms use 1"-14 threads and include secure jam nuts for reliable, set-and-forget adjustment.
