Mercedes Suspension Air Strut - Bilstein 44-289300

Product Information

An air suspension strut is a key component in vehicles equipped with air suspension systems. It combines a traditional shock absorber with an air spring (a rubber bladder filled with pressurized air). The strut supports the vehicle’s weight, absorbs road impacts, and adjusts ride height for comfort and handling. Over time, the air bladder, seals, or internal shock can wear out, leading to ride and handling issues.

• Sagging or uneven ride height – one corner or the entire vehicle sits lower than normal.
• Rough or bouncy ride – poor damping from a worn shock or air bladder leak.
• Air compressor overuse – system runs constantly to compensate for air leaks in the strut.

About Bilstein B4 OE Replacement

Bilstein shocks and strut perform due to their larger piston area and quality manufacturing. Bilstein shocks eliminate dead spots, and deliver extremely responsive valving for superior performance and handling, including consistent, fade-free damping and shorter braking distance. Made only from the highest quality materials, Bilstein shocks reduced valve fatigue means they last much longer than standard stock replacement components. Bilstein Touring (B4): The Bilstein B4 Series provides the same OEM quality and ride stability for the aftermarket. Bilstein uses both monotube and twin-tube technology to give the best in OE replacement driving comfort at a great economical price. This class shock is considered by FCP to be a stock replacement or “one step up” from factory replacement shocks.
