JKS Manufacturing Jeep Wrangler TJ/LJ Adjustable J-Flex Upper Control Arms - Rear

If you're working on a 1997-2006 Jeep Wrangler TJ or LJ, these JKS J-Flex adjustable rear upper control arms are a solid option for improving your suspension geometry. They help you dial in caster and axle positioning, especially when you've got a lift kit from 0 to 4 inches, using the factory mounting points. This means you can get your alignment dialed in just right after lifting your Jeep.

These arms are built tough. They're CNC-bent from strong DOM tubing, and the adjustable end uses a forged flex joint that's fully rebuildable and greaseable, so you can keep it working smoothly for a long time. The heavy-duty 1-1/4"-12 threads make adjustments easy with the included jam nuts. On the other end, factory-style rubber bushings help keep things quiet and maintenance-free. They're also powder-coated to resist corrosion and include integrated tabs for your e-brake cables.
