Detailed Description

The KYB Mount Components line focuses on suspension replacement parts that restore original ride behavior without changing the vehicle’s intended geometry.

For drivers searching for a front strut mount kit for 2003-2009 Lexus GX470 models, KYB SM5724 provides a direct-fit service part built around the application.

This part cross-references Lexus 4859760060 and 9094802159 for the same application.

What It Helps Solve

• Front-end clunking or knocking from worn strut mounts
• Excess vibration and road noise entering the cabin
• Steering effort that feels rough or inconsistent
• Alignment issues caused by worn mount bearings
• Harsh impact transfer from deteriorated suspension insulators

Installation Notes and Tips

Install SM5724 on the front suspension only and verify the mount orientation before assembly. Because strut mounts affect steering pivot and wheel alignment, a professional alignment check is recommended after service. Inspect the strut assembly, bearing plate, and surrounding suspension components for wear before reassembly.
