Smooth out a harsh, noisy front ride with the KYB strut mount SM5260, a direct-fit replacement for the FRONT position on a wide range of BMW models — including the 1999-2000 and 2007-2013 328I, 2001-2006 325I and 330I, 2007-2013 335I, 2001-2007 525I and 530I, 2006-2010 550I and 650I, 2013-2015 X1, 2004-2010 X3, and 2009-2016 Z4. See the Buyer's Guide tab for the full list of 37 applications.

Old, hardened vibration insulators let road impacts, noise and harshness pass straight into the cabin. Designed as an OE-quality replacement for each application, this KYB suspension strut mount cushions those impacts to reduce the jarring, noise and vibration a worn mount transmits.

  • Superior rubber: reduces noise, vibration and harshness.
  • Front bearing plate: serves as the steering pivot and helps support vehicle weight — critical to steering performance and wheel alignment.
  • Mount bearing: provides smoother steering and helps retain front-end alignment.
  • Matched-grade studs and nuts: included for correct fitment.

KYB strut mounts and bearing plates have a long-standing reputation for high quality. If a failed or hardened strut mount is the source of your front-end noise or vibration, this replaces it.

Frequently Asked Questions

What is a KYB strut mount and what does it do?

It is the FRONT upper mount that connects the strut assembly to the body. Its rubber cushions road impacts to reduce noise and vibration, while the bearing plate acts as the steering pivot and helps support vehicle weight.

Does the SM5260 fit my BMW?

It is a FRONT-position mount cataloged for many BMW models, such as the 2001-2006 325I and 330I, 2007-2013 335I and 2004-2010 X3. Check the Buyer's Guide tab to confirm your exact year and model among the 37 applications.

What are the signs my strut top mount may need replacing?

Common signs include increased noise, vibration or harshness through the front end, clunking, or steering that feels less smooth. Have the cause diagnosed, since these symptoms can come from other worn suspension parts.

Does this KYB shock mount come with hardware?

Yes — it includes matched-grade studs and nuts for correct fitment. Consult the vehicle service information for the proper torque specifications during installation.

Should I replace both strut mounts at once?

Because both sides typically wear at a similar rate, replacing them as a pair is a common best practice for balanced steering and ride. This listing covers the parts as cataloged for the FRONT position.
