BMW 6863739 Control Arm — a genuine used OEM front left control arm, also superseding 6863733. This stamped-steel arm connects the wheel hub to the chassis frame, allowing vertical wheel travel while maintaining alignment. When worn, it often produces a clunk over bumps or causes vague steering and uneven tire wear on your i3 or i3s (fits both battery-electric and range-extender variants).
