Product Details

KYB Mount Components SM5971 is engineered for front suspension service where the original strut mount has hardened, cracked, or lost its ability to isolate vibration. On BMW X3 and BMW X4 models, the strut mount plays an important role in steering response, suspension movement, and ride quality. KYB uses application-specific OE-style construction to help restore the original mounting function and reduce the jarring effect that worn mounts can transmit into the cabin. This part cross-references BMW 31306852158 for the same application.

What It Helps Fix

  • Clunking or knocking from the front suspension
  • Excess vibration felt through the body or steering
  • Noise caused by hardened or deteriorated mount insulators
  • Steering feel affected by worn front bearing plate support
  • Alignment concerns related to mount wear
