OE Replacement Series Details

Bilstein’s B3 OE Replacement line is focused on restoring suspension function to factory specifications rather than changing the vehicle’s original setup. For Mercedes-Benz E320 and Mercedes-Benz E430 front suspension service, part number 36-266166 is engineered to match the original spring profile so the vehicle maintains the intended stance and handling balance. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
