Product Description

The Bilstein 24-011839 B4 OE Replacement front shock absorber is designed as a reliable direct replacement for the front suspension on Mercedes-Benz S-Class models of the W126 sedan and C126 coupe from 1981 through 1991. Built to match original equipment performance, this monotube gas pressure shock helps restore factory-level ride comfort, handling stability, and damping consistency, making your vehicle feel more controlled and composed over varied road surfaces.

This shock installs easily into the vehicle's original mounting points and works with the stock springs to maintain the factory ride height and suspension behavior. Its durable protective finish helps resist corrosion over time. Sold individually, it's recommended to replace both front shocks at the same time to preserve balanced suspension performance and even handling characteristics across the front axle. This makes the 24-011839 an excellent choice for restoring worn shocks or refreshing the suspension on classic S-Class models.
