Control arms are critical suspension components that connect the wheel hub to the vehicle's frame. After years of service, non-serviceable ball joints and mounting points can wear out, causing poor handling, uneven tire wear, and suspension noise. Because some components cannot be replaced, the only solution is replacement of the entire arm. URO manufactures this control arm to meet or exceed OE specifications for proper fitment and performance. If replacing any part of your front or rear suspension, it is best to either do it in pairs (both left and right sides), or examine parts that are prone to failure.

URO Parts specializes in OE-grade replacement components for European vehicles, offering quality alternatives to dealer pricing while maintaining exacting standards for fit and function.
