MOOG Front Left Lower Control Arm and Preinstalled Ball Joint Assembly RK623522 for Mazda CX-5 / Mazda 6 — Direct-Fit, Corrosion-R

MOOG RK623522 is a direct-fit front left lower suspension control arm and integrated ball joint assembly engineered to restore proper wheel alignment and stable steering for compatible Mazda models.

If your Mazda CX-5 or Mazda 6 shows uneven tire wear, wandering steering, or a vague front-end feel, replacing the lower control arm with a high-quality OE-style assembly can resolve alignment drift and return predictable handling. This MOOG RK623522 assembly combines a robust control arm with a preinstalled ball joint, manufactured for structural integrity and corrosion resistance so installation is straightforward and long-lasting.

How does this control arm assembly improve steering and alignment?

The MOOG RK623522 re-establishes the suspension geometry that keeps wheels tracking true. By replacing worn or bent components with a precisely engineered arm and ball joint, you regain correct caster and camber relationships that affect steering response.

• Preinstalled ball joint ensures accurate pivot points and easier installation.
• Proper geometry reduces uneven tire wear and steering pull.
• Engineered stiffness resists deflection under cornering loads.
