Product Details

Bilstein’s B1 OE Replacement line focuses on direct replacement suspension parts that restore factory-style function without changing the vehicle’s original suspension layout. This rear strut mount is part of that OE replacement approach and is intended for BMW rear suspension applications across 1992-2006 model years, including 325i, 330i, M3, Z3, and related 3 Series variants. The black-painted finish provides a clean, service-ready appearance, and the mount supports proper strut positioning in the rear suspension assembly. This part number 12-117109 is also referenced for BMW rear strut mount service on E36 and E46-era vehicles.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
