Why Bilstein B4 OE Replacement (Air) for This Application?

This B4 OE Replacement Air component is intended to restore the vehicle's original air-suspension function with an application-matched Bilstein replacement rather than converting the chassis to a conventional spring/damper layout. For the Mercedes-Benz application shown here, Bilstein assigns this product to Front Right, Front Left, so the part should be chosen by both chassis fitment and suspension position.

Choosing the Right Bilstein Setup

For this road-focused application, the priority is controlled body motion and a composed ride without introducing unnecessary suspension changes. The exact Bilstein configuration should be matched to the vehicle's factory suspension equipment, especially where adaptive or air suspension is involved. If the vehicle has been lowered, lifted, converted from factory electronic suspension, or carries substantial added weight, verify that this exact Bilstein series and part number matches that configuration before purchase.

Fitment Considerations

Confirm the vehicle's year, model, drivetrain and existing suspension configuration before ordering. Bilstein fitment can vary by axle, body style, factory suspension package and ride-height configuration even within the same model range.
