Front Passenger Side Lower Control ArmPrecision Suspension Performance for Lexus IS SedansRestore the legendary handling and steering response of your luxury sedan with this premium Front Right (Passenger Side) Lower Control Arm. Engineered specifically for the third-generation Lexus IS chassis, this arm is a critical component for maintaining wheel alignment and absorbing road impacts. Over time, the factory bushings—especially the large rear-compliance bushings—can crack or leak, leading to symptoms such as front-end "clunking" over bumps, vague steering feel, and accelerated inner tire wear.This assembly is constructed from high-grade Aluminum to match the factory weight and strength specifications, ensuring your vehicle maintains its original suspension dynamics and unsprung weight balance. The unit comes pre-fitted with high-durability rubber bushings to eliminate noise, vibration, and harshness (NVH), providing a comprehensive "bolt-in" solution for your front suspension.Fitment Verification and Vehicle ApplicationsThis control arm is designed for the Front Passenger Side (Right) Lower position. Please verify your vehicle's drivetrain, as suspension geometry differs significantly between RWD and AWD models: Lexus IS200t: 2017. Lexus IS300: 2018, 2019, 2020 (Rear-Wheel Drive / RWD ONLY).

The suspension must be under the vehicle's full weight (on the ground or on drive-on ramps) before final torquing. Tightening while the suspension is hanging will "bind" the rubber, leading to premature tearing within a few months. Alignment Required: Replacing a lower control arm alters your vehicle's camber and toe settings. A professional four-wheel alignment is mandatory following installation to prevent rapid tire scrubbing and to ensure the steering wheel remains centered. Inspect the Ball Joint: Since this arm features a "Bolt-In" ball joint mounting type, inspect your existing ball joint for play. If it shows any signs of wear, it is highly recommended to replace it at the same time as the arm for a complete front-end refresh. Aluminum Care: Aluminum suspension components are sensitive to surface damage. Avoid using heavy pry bars or hammers directly on the aluminum body of the arm during installation to maintain its structural integrity.
