The Sachs 31 31 6 873 757 is a front left suspension strut engineered to OEM specifications for BMW 4 Series vehicles.

• Direct OEM Replacement: Drop-in fitment designed to replace the original front left strut without modification
• Left Front Position: Designed specifically for the driver-side front suspension; sold individually
• Excludes Adaptive M Suspension: For use on vehicles without adaptive or active M chassis suspension systems
