Product Details
The Bilstein B4 OE Replacement line is focused on restoring original suspension behavior rather than changing the vehicle’s character. Part number 21-031199 is a front strut cartridge for select BMW 5 Series models, including the BMW 525i, BMW 530i, BMW 540i, and BMW 535i. Its twintube construction supports controlled damping for drivers replacing worn factory struts on street-driven vehicles.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Excessive front-end bounce after the original strut wears out
