Product Details

KYB Excel-G is engineered on OE assembly lines using OE-quality components and calibrated to return the suspension to its original operating characteristics rather than change them. For BMW 525i, BMW 528i, and BMW 530i front left applications, part number 334675 supports consistent damping performance, stable lane changes, and predictable braking feel. This part cross-references Monroe Shocks & Struts 71456 for the same application.

What This Strut Helps Address

• Excessive front-end bounce or oscillation
• Loose steering feel or delayed steering response
• Nose dive during braking
• Uneven tire contact caused by worn damping control
• Body movement and instability over bumps or during lane changes

Installation Notes and Fitment

Compatible with select BMW E39 front left applications. Fits 2003 BMW 525i, front left; Fits 2001-2003 BMW 530i, front left; Fits 2001-2002 BMW 525i, front left; Fits 1997-2000 BMW 528i, front left. Notes vary by model and year: exclude M-Technik suspension and electronic suspension where listed, and some 2003 525i applications are available only while supplies last. Verify the upper mount type 14X1.50 and confirm suspension configuration before installation. KYB recommends replacing the strut mount, part number SM5260, and protecting the assembly with strut boot SB110 to reduce noise, vibration, and contamination.

Quality Assurance

KYB is a major OE supplier, and Excel-G is built to OE-style standards on the same manufacturing lines used for original equipment production. The design focuses on restoring factory ride control and maintaining suspension performance for electronic safety systems that depend on proper suspension, brake, and tire operation.
