Moog RK623993 Suspension Control Arm and Ball Joint Assembly

The Moog RK623993 is a direct-fit suspension control arm and ball joint assembly engineered to restore proper steering geometry, ride quality, and handling stability. As a critical link between the wheel assembly and the vehicle's chassis, the control arm guides wheel movement through the full range of suspension travel while the integrated ball joint provides the pivoting connection to the steering knuckle.

Key Features:

• Direct-Fit Replacement: Precision-engineered to match OE specifications for a straightforward, no-modification installation
• Pre-Installed Ball Joint: Comes fully assembled with the ball joint already installed, reducing labor time and simplifying the repair
• High-Strength Steel Construction: Heat-processed arm material matches or exceeds OE requirements to resist fatigue, bending, and premature failure
• Corrosion Protection: E-coated arm and coated ball stud help inhibit rust and corrosion caused by road salt, grime, and moisture
• Sealed Socket Design: Ball joint socket is sealed against contamination for maintenance-free, long-lasting operation
• Laser-Etched ID: Provides visible confirmation of genuine Moog quality and part authenticity
• Flaw-Detection Tested: Each assembly undergoes rigorous inspection to ensure it meets OE specifications and avoids early failure

Common symptoms of a worn control arm or ball joint include pulling to one side during braking, a loose or wandering feeling in the steering wheel, clunking noises over bumps, and uneven or excessive inner tire wear. Replacing the assembly with the Moog RK623993 helps restore confident, precise steering response and consistent suspension geometry. Moog is recognized throughout the automotive industry as the Problem Solver, backed by decades of engineering expertise and nearly 50 design-enhancement patents.
