Detailed Product Description

The Moog RK641863 suspension control arm is engineered to maintain proper wheel alignment and suspension geometry on compatible Lexus Highlander and Toyota RX300 vehicles. Its stamped steel construction ensures structural integrity under normal driving conditions, while the black painted finish helps resist corrosion. The included rubber bushings provide necessary flexibility and reduce noise and vibration, contributing to a smoother ride. This control arm does not come pre-greased and lacks a grease fitting, so maintenance should be performed according to vehicle service guidelines. The absence of a ball joint and mounting hardware means these components must be sourced separately if needed.
