Part number: 22-240583

Restore sharp, confidence inspiring road holding on your BMW with this front left OEM-quality damper from Bilstein. This direct-fit nearside strut is designed for BMW 1 Series F20 F21 and BMW 2 Series F22 F23 models equipped with M suspension and xDrive all wheel drive, including M135i, M140i, M235i and M240i.

We run these on our own vehicles and customer cars, and the feedback is consistently positive for ride quality, body control and everyday drivability.
