Description
Heavy Duty Front Shock Absorber – Mercedes W126 C126
Bilstein B4 Heavy Duty shock absorber for the front axle of the entire Mercedes W126 and C126 series, both before and after MOPF.
This is our first choice for the W126 and C126. We use heavy-duty shock absorbers as much as possible in our own workshop and also install them on our own cars.
The Heavy Duty version ensures a better body control, less body roll, and better handling of larger suspension movements and shocks. As a result, the car feels more stable and quieter than the standard version, without compromising the comfortable character of the W126 and C126.
This is the shock absorber that we frequently use and recommend in our own workshop. The Heavy Duty version does not necessarily make the suspension stiffer, but primarily ensures better body control. As a result, the car feels more stable and composed, without compromising ride comfort.
Price per piece. For one car are 2 shock absorbers necessary.
