Product Details

The Bilstein B3 OE Replacement line is built for drivers who want suspension parts that follow factory specifications rather than altered ride characteristics. This rear coil spring is engineered to match the original spring design used on compatible BMW applications, helping maintain the vehicle’s intended stance, load support, and suspension response. If you are replacing a worn rear spring on a BMW 740i, BMW 740iL, or BMW 750iL, part number 36-153947 provides an OE-style solution for restoring the rear suspension system.

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

Installation Notes and Tips

Verify the vehicle’s rear suspension configuration before ordering, including standard suspension with self-leveling suspension. Compare the original spring’s shape, height, and seating points to confirm correct application. Professional installation is recommended because coil spring service requires proper suspension compression and safe handling procedures.

Quality Assurance

Bilstein manufactures the B3 OE Replacement series to OE dimensions, spring rates, and design types so the replacement spring follows factory specifications for the intended BMW applications. The black powder coat finish adds a durable protective layer for everyday suspension service.
