Bilstein B4 OE Replacement Front Left Strut Assembly - Tesla Model 3 / Model Y 2018-2024

The Bilstein B4 OE Replacement damper restores the original ride quality, handling, and safety of a vehicle running worn factory struts, built to match or exceed the specification and function of the unit the car left the factory with. This application uses a twin-tube gas pressure design with a fixed spring seat, a stem-type upper mount, and a clevis lower mount. It is supplied as the damper unit itself: no coil spring, strut mount, bearing, boot, or bump stop is included, so the factory components carry over during installation.
