Moog RK624122 Suspension Control Arm and Ball Joint Assembly

The Moog RK624122 is a premium replacement suspension control arm and ball joint assembly engineered for the Lexus LS500. As part of Moog's R-Series (RK) lineup, this assembly delivers a value-driven, direct-fit solution that restores proper suspension geometry, steering response, and ride quality to OE or better standards.

Key Features:

• Direct-Fit Replacement: Precision-engineered tolerances ensure a drop-in fit with no modifications required, simplifying installation and steering alignment
• Pre-Installed Ball Joint: Arrives as a complete assembly with the ball joint pre-installed and sealed sockets for maintenance-free, long-term operation
• Enhanced Structural Strength: Heat-treated cast iron and steel construction is engineered to meet or exceed OE load and fatigue requirements
• Corrosion Protection: E-coated steel and coated ball studs resist rust, road salt, grime, and moisture to extend service life
• Optimized Bushings: Engineered bushings minimize noise, vibration, and harshness (NVH) for a quieter, more controlled ride
• Laser-Etched ID: Visible quality assurance marking confirms genuine Moog R-Series part authenticity

A worn or damaged control arm can cause the vehicle to pull to one side, produce clunking noises over rough roads, create a loose or wandering steering feel, and lead to excessive or uneven tire wear. Replacing the assembly with the Moog RK624122 restores wheel alignment integrity and confident vehicle handling. This assembly is backed by Moog's reputation as The Problem Solver — a standard of quality established since 1937.
