Quiet a harsh, noisy front end with the KYB strut mount kit SM5779, a direct-fit front replacement for the 2007-2017 Lexus LS460 (see the "Vehicles it fits" section for the full engine-level fitment). Built to KYB's OE-quality standard for the specific application, this kit supplies the strut mount, insulator with bellows, and bumper to replace old, hardened components that transmit road impacts, noise, and vibration into the cabin.
- Superior rubber: designed to reduce noise, vibration, and harshness from worn insulators.
- Mount bearing: the front bearing plate is a steering pivot that supports vehicle weight, helping provide smoother steering and retain front-end alignment.
- OE-quality replacement: engineered for this application to help restore original suspension feel.
- Matched grade studs and nuts for correct fastening.
If worn or separated front strut mounts are behind clunking over bumps, steering bind, or excess vibration, this kit replaces them. As a paired wear component, replacing both left and right mounts together is recommended for balanced, even suspension performance.
