OE Replacement (Air) Series Details

Common Replacement Reasons

• Rear suspension sagging or uneven ride height
• Loss of damping control over bumps and dips
• Air shock leakage or worn internal components
• Ride quality changes on Mercedes-Benz GLE, GLS, GL, or ML rear suspension systems
• Need for an OE-style replacement with factory-style connector fitment

Installation Notes

Verify the vehicle’s rear suspension type before ordering, since fitment depends on air suspension or electronic suspension configuration. Confirm the original mount style and connector layout against the removed unit, and inspect related air suspension components for wear before installation. Part number 27-271001 is designed for direct replacement on listed Mercedes-Benz rear applications.

Quality Assurance

Bilstein manufactures B4 OE Replacement (Air) dampers as OE-style service parts for European vehicles, with construction intended to meet or exceed manufacturer standards for the original air suspension application. The monotube design supports consistent damping performance in the rear suspension.
