Moog RK623023 Suspension Control Arm and Ball Joint Assembly

The Moog RK623023 is a premium suspension control arm and ball joint assembly engineered to restore proper steering geometry, ride quality, and vehicle stability. Moog's reputation as the chassis industry's Problem Solver is backed by decades of engineering innovation — this assembly is built to meet or exceed original equipment specifications.

Key Features:

• Direct-Fit Replacement: Designed as a direct OE replacement for straightforward installation and proper fitment without modification
• Enhanced Structural Strength: Heat-processed construction matches or exceeds OE requirements to resist premature failure
• Corrosion Protection: Coated studs and e-coated cast iron and steel construction help inhibit rust and premature wear
• Carbon Fiber-Reinforced Bearing: Induction-hardened stud combined with a carbon fiber-reinforced bearing reduces socket friction for extended service life
• Pre-Installed Ball Joint: Comes with the ball joint pre-installed for added convenience and reduced installation time
• Flaw-Detection Tested: Each assembly undergoes rigorous testing to ensure it matches OE specifications and avoids early failure
• Laser-Etched ID: Provides visible assurance of genuine Moog quality

A worn or damaged control arm can cause pulling, wandering, loose steering feel, clunking noises over rough roads, and uneven tire wear. Replacing the control arm and ball joint assembly as a unit restores proper suspension geometry and helps bring steering response and ride quality back to factory standards. Moog's RK623023 is engineered for structural strength, long service life, and reliable performance across a wide range of driving conditions.
