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 Buyer's Guide tab 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.

Frequently Asked Questions

What vehicle does the KYB SM5779 strut mount kit fit?

It's a direct-fit front replacement for the 2007-2017 Lexus LS460. Check the Buyer's Guide tab to confirm the engine-level fitment for your vehicle.

Is this a front or rear strut mount kit?

This is a front strut mount kit. The front bearing plate serves as the steering pivot and supports vehicle weight, making it critical to steering feel and wheel alignment.

What's included in this suspension strut mount kit?

The kit includes the strut mount, an insulator with bellows and bumper, plus matched grade studs and nuts for installation.

Should I replace both front strut mounts at the same time?

It's recommended. Replacing the left and right mounts together as a matched pair helps keep suspension performance even and balanced from side to side.

What are signs a front strut mount may need replacing?

Clunking or knocking over bumps, steering bind or binding, and increased noise and vibration can indicate worn mounts. Diagnose the cause first, since these symptoms can have other sources.
