Construction & Design

The Synergy Rear Upper Control Arm features a forged housing that delivers superior strength compared to stamped or cast alternatives. This robust construction ensures the control arm can endure the stresses of off-road driving and heavy-duty use without deformation or failure. The dual durometer bushings combine two different hardness levels of polyurethane, providing a perfect balance between vibration absorption and suspension precision. This design reduces unwanted movement and noise while maintaining the necessary flexibility for suspension articulation.

Precision engineering and quality materials make this control arm a reliable upgrade that enhances the Jeep Wrangler’s suspension system without compromising ride comfort or durability.
