JKS Manufacturing 18-21 Jeep Wrangler JL/JK Adjustable J-Flex Upper Control Arms - Rear

If you're working on your 2018-2025 Jeep Wrangler JL or JK and need to dial in your suspension geometry, these adjustable rear upper control arms from JKS Manufacturing are a solid option. They're designed to help correct alignment angles, especially after lifting your Jeep, which can improve both on-road handling and off-road articulation. These arms are built tough, using heavy-duty 2-inch OD by .250-wall DOM tubing that's CNC bent to ensure it clears your tires, frame, and axle properly.

At the axle end, you'll find OE-style rubber bushings. These are great because they absorb road noise and vibrations, giving you a more comfortable and quiet ride without needing any maintenance. On the frame side, JKS uses a unique hex-shaped bung for easy adjustments. The forged flex joint allows for up to 30 degrees of misalignment, which is key for getting impressive articulation when you're off-roading. Plus, these flex joints are greaseable to keep the bushings healthy and are rebuildable if needed down the road. They come fully assembled and finished in a durable gloss black powder coat.

These control arms are adjustable to work with lifts ranging from 0 to 6 inches, making them versatile for many setups. They are sold in pairs, so you get both sides for your rear suspension.
