Bilstein Shock Absorber B4 Rear 46mm 2006 BMW X5 4.4i

Bilstein Shock Absorber B4 Rear 46mm 2006 BMW X5 4.4i provides OE-replacement damping for the rear of the 2006 BMW X5 4.4i, restoring ride control and stability when replacing the original air suspension components.

This Bilstein B4 unit is engineered as an OE Replacement (Air) damper intended to directly replace factory air suspension dampers on compatible European vehicles. As an established OE supplier for air suspension systems, Bilstein's manufacturing and quality processes are used here to meet, and typically exceed, the standards set by the vehicle manufacturer.

• OE Replacement (Air) design — matches the original damping function and mounting interfaces for straightforward retrofit into the vehicle's air suspension circuit without re-engineering the chassis attachment points.
• Bilstein OE supplier quality — produced to the supplier-level standards Bilstein provides to manufacturers, which supports consistency in damping performance and long-term reliability.
• 46mm damper body — the specified body diameter corresponds to the original equipment sizing used on the vehicle for compatible structural fit and expected oil/valve capacity for damping control.
• Rear application for 2006 BMW X5 4.4i — configured for the rear axle on this model, ensuring the damper's valving and form factor align with the vehicle's rear suspension requirements.

Why this matters:

• Direct replacement compatibility — reduces installation time and the need for supplemental components or modifications when replacing worn air dampers.
• Consistent damping characteristics — maintains the vehicle's intended balance between ride comfort and control, helping preserve handling predictability and passenger comfort.
• Supplier-level quality control — production and testing standards aim to deliver consistent units that meet manufacturer expectations for durability and performance.

Brand notes: Bilstein is recognized as an OE supplier for air suspension components on many European vehicles; this product leverages that heritage to provide a like-for-like service replacement.
