Detailed Description

KYB Excel-G part number 341840 is engineered for drivers who want to restore factory ride control on a BMW 528i rear suspension. The design uses OE-quality components and KYB’s calibrated damping approach to bring back the original balance of comfort, stability, stopping control, and lane-change response. For BMW 5 Series applications, that means predictable handling and consistent suspension behavior under everyday driving conditions.

The lower mount type is E2(15.4X66) and the upper mount type is S1. Part number 341840 is also a direct OE-style replacement for BMW numbers 33521093646, 33521094467, and 33621094467.

What This Strut Helps Address

• Excessive rear bounce or oscillation
• Loose or unstable handling in the BMW 528i
• Reduced steering response during lane changes
• Uneven tire contact caused by worn damping control
• Suspension noise or vibration associated with worn struts

Installation Notes and Tips

Fits 1997-2000 BMW 528i, rear. This application is for vehicles without electronic suspension. KYB recommends replacing strut mounts, part number SM5251, to reduce noise and vibration, and using strut boot SB107 to help protect the new strut from dirt, debris, and salt. Verify mount style and suspension configuration before installation.
