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 fits many vehicles as a direct-fit replacement, among them the 2006-2013 Lexus IS250, 2011-2013 Lexus IS350 and 2007-2011 Lexus GS350 — see the "Vehicles it fits" section for the full list.
KYB assembles this kit with the strut mount, spring seat, bellow and bumper, plus matched-grade studs and nuts. 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.
