Ball joints are essential suspension components that connect the control arm to the steering knuckle, allowing for smooth articulation and steering control. The 555 brand is recognized worldwide for manufacturing high-quality steering and suspension parts that deliver reliable performance. This upper ball joint helps maintain proper wheel alignment, steering response, and ride quality while supporting the weight of the vehicle.

Application Note: This is a single ball joint sold individually. Most vehicles require two upper ball joints for complete front suspension service. Professional installation is recommended to ensure proper torque specifications and suspension alignment.
