Quiet the ride and steady your steering with the KYB strut mount kit SM5738, a front suspension strut mount kit built to replace old, hardened vibration insulators. It drops in as a direct-fit replacement for the 2006 Lexus GS300, 2006-2013 Lexus IS250, 2007-2011 Lexus GS350, and 2011-2013 Lexus IS350 — see the Buyer's Guide tab for engine-level details.
KYB assembles this kit with the strut mount, spring seat, bellow and bumper, plus matched-grade studs and nuts, to restore the connection between each front strut and the body. The front bearing plates act as steering pivots and help support vehicle weight, making them critical to steering feel and wheel alignment.
- Superior rubber: cushions road impacts to reduce noise, vibration and harshness transmitted into the cabin.
- Mount bearings: provide smoother steering and help retain front-end alignment.
- Matched-grade hardware: includes matched studs and nuts for installation.
- Kit contents: strut mount, spring seat, bellow and bumper in one package.
Signs a front strut mount may need replacing include clunking or vibration through the steering, noise over bumps, or binding steering. If a worn mount is the cause, this kit replaces it.
