Show original supplier description

The Genuine BMW left front spring strut (part number 31316873803) is engineered as a direct replacement for the original component on select BMW 3 Series vehicles. As a genuine BMW part, it is manufactured to stringent OEM standards, ensuring the same quality and performance as the part that came with your car. This strut assembly is crucial for maintaining ride quality and handling performance. Symptoms of a worn strut assembly can include noise over bumps, abnormal tire wear, vehicle wandering, poor steering response, and a harsh ride. It effectively dampens the compression and rebound of the coil spring, contributing significantly to a comfortable and controlled driving experience. For optimal results and to ensure proper suspension function, it is highly recommended to replace strut assemblies in matched pairs, and to also replace the bump stops as per BMW's recommendations. This part is specifically designed for the 2016-2018 BMW 320i xDrive, 2016-2018 BMW 328d xDrive, 2016 BMW 328i xDrive, and 2017-2018 BMW 330i xDrive models. It is important to note that this strut is **not** for cars equipped with Adaptive M Suspension (S2VFA).
