Product Details

The KYB SM5752 is part of KYB’s Mount Components line, which focuses on replacing worn vibration insulators and restoring suspension performance to original-equipment standards. On BMW rear upper applications, a worn mount can transmit road impact, clunks, and vibration into the body. Replacing it with the KYB SM5752 helps return the suspension to a quieter, more controlled feel while supporting correct alignment behavior where the mount and bearing assembly are part of the system.

This part cross-references BMW 33506767010 and Monroe Shocks & Struts 907984 for the same application.

What It Helps Fix

• Rear suspension noise over bumps
• Harsh vibration felt through the chassis
• Clunking from hardened or worn strut mount insulators
• Steering or alignment issues related to worn mount bearings
• Loss of ride control from deteriorated upper mount components

Installation Notes

Install the SM5752 on the rear upper position only for the listed BMW applications. Verify vehicle suspension type before ordering, since the BMW M3 listing is not compatible with electronic suspension systems and the 2006 325i and 330i listings include suspension exclusions. Always confirm the exact model, year, and suspension configuration against the fitment notes before service.

Quality Assurance

KYB is known for OE-style suspension replacement parts, and this mount is engineered to meet application-specific requirements for fit, function, and durability. The SM5752 is built to address the wear patterns common to aging strut mounts and bearing plates in BMW rear suspension service.
