Product Details
The Bilstein B3 OE Replacement line focuses on restoring original suspension function rather than changing ride height or handling balance. This rear coil spring is built to the original specifications used on the vehicle, helping maintain the intended load support and suspension behavior on the BMW 525i and BMW 525iT. If you are replacing a fatigued rear spring on a 1992-1995 BMW 525i, rear, or a 1993 BMW 525iT, rear, this OE-style spring is a direct service part under part number 36-278114.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Problems This Part Can Address
- Sagging rear ride height from a worn spring
- Uneven rear suspension stance on BMW 525i or BMW 525iT models
- Loss of factory spring rate after long-term use
- Noisy or unstable rear suspension behavior caused by spring fatigue
- Need for OE-spec replacement during suspension service
