KYB Suspension Strut Mount P/N:SM5258
KYB Suspension Strut Mount P/N:SM5258
$101.99

Quiet a harsh, vibrating ride and keep precise steering with the KYB strut mount SM5258, a front right suspension strut mount that drops in as a direct-fit replacement for the 1995-1999 BMW M3. As the top connection between the strut and the body, it cushions road impacts and locates the strut, while its bearing plate acts as the steering pivot and helps support vehicle weight — so a worn, hardened mount lets extra noise, vibration and harshness reach the cabin.

  • Superior rubber: helps reduce noise, vibration and harshness transmitted through the mount.
  • Mount bearing: provides smoother steering and helps retain front-end alignment.
  • Matched-grade studs and nuts: included for a secure fit.
  • Application-specific build: an OE-quality replacement designed for the listed vehicle.

KYB strut top mounts and their bearing plates are built to a high replacement standard, so this is a straightforward way to refresh a tired top mount. Sold individually as one mount; replacing the left and right mounts together as a set is good practice for balanced steering and ride.
