Front Left Spring Strut

The BMW Genuine Parts 31312282459 is an OEM front left spring strut engineered by Sachs, an original equipment manufacturer for BMW. This part is designed to directly replace the original strut on E46 323i, 325i, 328i, and 330i models produced between 2002 and 2006, specifically those equipped with the Sport or M Sport suspension package. It aims to restore the factory-intended sport suspension handling and ride characteristics. Sachs, as a trusted original supplier to BMW for suspension components like shocks, struts, and mounts, ensures this part meets BMW's original design, fitment, and performance specifications. It holds TUV approval, signifying adherence to rigorous quality and safety standards. While other aftermarket brands may offer more performance-oriented options, this Sachs strut is the ideal choice for those seeking to maintain the original BMW ride and handling experience. It is crucial to note that front struts should always be replaced in pairs to ensure consistent handling and prevent discrepancies in performance. Therefore, it is recommended to order both the left and right front struts. Additionally, essential installation components such as new mounts, dust boots, spring pads, and bump stops are sold separately and must be acquired for proper installation. Application notes indicate that front struts for E46 non-M RWD vehicles are largely interchangeable; however, BMW may list different part numbers for vehicles with very similar specifications. To avoid minor differences in length and pressure, it is advisable to inspect the original strut for its part number when replacing only one side at a time, though replacing in pairs is always the preferred method. This Sachs strut is compatible with BMW part number 31312282097. It's important to understand that the "E46 sport suspension" designation does not encompass aftermarket sport springs from brands like H&R or Eibach, which are typically shorter. For vehicles fitted with such aftermarket springs, shorter struts like Bilstein Sport or Koni Sport are required. This OEM strut comes with a two-year warranty. For precise BMW fitment or expert assistance, contacting a BMW specialist is recommended.
