MetalCloak Duroflex Control Arms – Upper Front for Jeep Wrangler TJ/LJ 1997–2006 These adjustable MetalCloak upper front control arms with Duroflex joints are built for real-world off-road use: strong articulation without the typical suspension bind, and without harsh vibration on the street.
A thick-wall DOM tube, a forged threaded end, and a precise jam nut make it easy to set length and keep your settings locked in under demanding conditions. Gold Zinc finishing helps protect the components from corrosion.

Product overview
Upper front control arms kit with Gold Zinc finish. Key benefits Big suspension freedom thanks to high joint misalignment (over 34°; up to 68° per arm). Smooth, street-friendly movement without binding – Duroflex self-centers and helps reduce vibration. Adjustable length helps correct geometry after a lift or other suspension changes. Heavy-duty 3/16"-wall DOM tubing and forged threaded ends for off-road loads. Low maintenance with a rebuildable joint (service instead of replacing the whole arm). Gold Zinc coating helps resist corrosion. GIF: Duroflex vibration damping & self-centering
The joint moves smoothly and returns to neutral, helping keep daily driving comfortable. GIF: high misalignment range
High misalignment translates into real articulation without suspension bind. GIF: micro-motion during driving
Duroflex handles small, rapid movements to help improve ride quality and reduce typical joint wear. GIF: macro-motion / articulation
Large range of motion at full flex helps keep traction off-road. What’s included Upper front control arms. All required mounting hardware. What’s in the kit
