Regardless of the purpose of using your car, we want you to get the most comfort and safety from it. Shock absorbers play an important role in this. There have been many different designs for shock absorbers over the course of automotive history. But in this article, we will compare mono-tube and twin-tube shock absorbers.

Manufacturers agree that mono-tube is better, but is that really true? Of course, they have many advantages:
- The larger oil capacity allows generate stable damping force and improves heat dissipation.
- There are no restrictions on installation angles.
- There is no aeration due to design of shock absorber
The mono-tubes are more durable and also require minimal maintenance, but they are more expensive than twin-tubes. In addition, the mono-tube shocks ride tends to be stiffer, because of an injection of high-pressure gas. And also maintaining sufficient stroke is difficult due to the location of the gas and oil chamber. So the mono-tube’s merits are suited for hard-driving on circuits.
The big problem with mono-tubes is that if the casing consisting of one cylinder is damaged, the shock absorber can no longer move. Often this happens when driving on ordinary roads or off-road because you never know what may be on their surface.
The use of a two-tube shock allows for a more comfortable ride, eliminates the load on the seals and reduces friction due to the low gas pressure.
The disadvantages of double-tube shock absorbers are the features of their design, which do not allow them to be mounted on a strut-type suspension. Also, the gas and oil chambers are combined, which is why you can often encounter aeration.
Furthermore, two-tube has a lower price compared to the mono-tube design, but this does not mean that you will lose in quality or in the performance of your car. Usually, you may feel the difference only in specially created conditions.
To sum up, both the mono-tube and twin-tube shocks have their pros/cons and both have different areas of use. It is not a matter of which design is better, but for what purposes will you use it.
