Product Details

When you're looking to get more out of your Jeep Wrangler JK, especially off-road, upgrading the front upper control arms is a smart move. What you get in this package are a pair of JKS Manufacturing J-Flex adjustable upper control arms. These aren't just any control arms; they're built to help you dial in your suspension geometry, which is key for optimizing tire, frame, and axle mount clearance, especially after lifting your Jeep.

JKS makes these arms from strong, CNC-bent DOM tubing, ensuring they clear your tires and mounting points properly. The real magic is in the forged 'flex' ends. They're adjustable, allowing you to fine-tune your suspension setup for better handling and performance on rough terrain. Plus, these ends are fully rebuildable and greaseable, meaning you can keep them in top shape for a long time. The heavy-duty 1/4"-12 threads and the hex-shaped bung make tightening the jam nuts straightforward and secure. On the other end, the mount is 'boxed' for extra strength, and the whole assembly is powder-coated to resist corrosion and look good.

These control arms are designed to fit your 2007-2017 Jeep Wrangler JK directly. They're a solid option for anyone looking to improve their Jeep's off-road capability and suspension tuning options.
