Product Description

The Bilstein 24-015363 B8 Performance Plus Rear Shock Absorber is a purpose-built upgrade for Mercedes-Benz S-Class vehicles on the W126 sedan and C126 coupe chassis from 1979 through 1991 that use a non-self-leveling rear suspension. This high-quality gas-pressurized monotube shock delivers more consistent damping performance compared to standard OEM shocks, resulting in improved vehicle control, better cornering stability, and a more composed ride quality.

Designed for enthusiasts and performance-minded drivers, this rear shock enhances stability during acceleration, braking, and rapid direction changes while retaining comfort on uneven surfaces. It's a direct-fit component engineered for the W126 and C126 platforms and is ideal for use with sport suspension setups or moderate lowering. Installation uses OE-style mounting points for a straightforward fit.
