Bilstein B4 DampTronic Front Left Strut

The Bilstein B4 OE Replacement (DampTronic) suspension strut assembly restores factory-style ride control for BMW models equipped with electronic suspension. Built as a direct OE replacement, this front left strut helps maintain original handling balance and ride quality while meeting or exceeding OE standards.

Detailed Product Overview

Bilstein 23-266469 is a front left suspension strut assembly for BMW 2 Series, 3 Series, and 4 Series models with DampTronic-style electronic suspension. It is engineered to preserve the original ride characteristics of the vehicle, making it a strong OE-style replacement for drivers who want factory-level response from the suspension system. This part cross-references BMW OE numbers such as 37 10 6 850 255 and 37 11 6 793 869 for the same application.

Compatible With BMW 230i xDrive, 330i xDrive, 340i xDrive, 430i xDrive, M240i xDrive, and other listed xDrive models in the 2013-2021 range, this Bilstein shock absorber assembly supports the original electronic damping setup. The B4 OE Replacement (DampTronic) series is focused on restoring the vehicle’s intended ride and handling response rather than changing suspension character.

What This Strut Helps Address

• Excessive front-end bounce or reduced damping control
• Uneven ride quality caused by a worn electronic strut
• Loss of factory steering feel and road stability
• Suspension warning symptoms related to aging OE dampers
• Restoration of original BMW ride behavior after strut wear
