The improved lane stability and optimum handling delivered by the BILSTEIN B6 pays off on poor or winding roads, as well as with heavily loaded vehicles or when towing a trailer. However, the precise handling of the gas pressure shock absorber is not only for safety, but also improves the driving experience. Thus, there are many arguments in favour of the BILSTEIN B6. However, many people do not know if the twin-tube or mono-tube version is preferable. The latter is increasingly being asked for by customers on the assumption that it is superior to the twin-tube version in every case. This can definitely not be confirmed on a general basis.
“Whether the twin-tube or mono-tube version is the right choice can only be decided individually according to the vehicle type and area of application. First of all there are obstacles regarding the installation. A B6 twin-tube damper can be installed up to a maximum inclination of 45 degrees. The mono-tube version, on the other hand, can even be installed upside-down. However, we will always find the best and most suitable solution for the customer,” explains Mustafa Yavuz, BILSTEIN Customer Service Manager and a master car mechanic by training. More than 90% of all series-produced vehicles are equipped with twin-tube shock absorbers as standard. The BILSTEIN B6, as an improved standard replacement for the twin-tube version, is therefore the most logical choice.
But when does the mono-tube version make more sense? Sports cars are the best example. They can benefit most from this technology. The B6 mono-tube models have a larger effective area of the working piston, ensuring higher damping force and better handling. Due to the so-called upside-down design with the characteristic “thick piston rod”, the front axle strut can also absorb much higher lateral forces, which results in even more precise steering behaviour.
Regardless of whether mono-tube or twin-tube technology is used: thanks to the same functional dimensions as the standard damper, replacing the springs is just as unnecessary as entering them into the vehicle documents. The conversion is therefore cheaper than a complete suspension. Drivers need not fear the loss of valuable features: special versions with DampTronic even retain all the functions of a standard active suspension with electronic control. This is where BILSTEIN’s original equipment expertise pays off all down the line.
