Why are Bilstein Shocks Used?

Bilstein was the first brand that introduced the patented gas pressure principle for controlling ride characteristics. They are also the first brand that features monotube gas pressure shock absorbers. 

In today’s world, they are in the lead of this monotube gas pressure shock absorbers technology. They are not only famous for single and twin tube MacPherson strut style suspensions but also known for monotube gas pressure shock absorbers

A good shock absorber provides a better riding experience, better handling, and control. While choosing a shock absorber, if you compromise any one of these that might create a problem in another one too. 

Bilstein is ahead of the game in this section. Their shock absorber design is more focused to reduce the need for any compromise. Bilstein shock absorbers feature rising rate valving shock absorbers which provide necessary dumping and also react quicker to road conditions. 

This allows great comfort while riding on rough roads. Bilstein shock absorbers are a combination of valving and high-pressure nitrogen gas which allows the tyre constant contact with the road. This feature provides safety with enhanced control.

Reasons Why Bilstein Shocks are Better

1. Heat Management:

A shock absorber usually heats up fast reducing its performance along the way. Heat is one of the major disadvantages to the performance and longevity of any brand shock absorber. Traditionally designed shock absorbers trap the heat within the shock body which allows them to build up heat and eventual failure. 

On the other hand, Bilstein featured monotube gas charged design which allows it to transfer the excessive heat from the oil to transfer it to the outer surface of the shock body and eventually dissipate more quickly and efficiently. 

The dividing piston feature in Bilstein shock absorbers also permits the oil to expand as the heat builds. It prevents foaming and viscosity loss. These features help the shock to maintain full damping characteristics even when temperatures rise.

2. Superior Design:

The design of the tube of Bilstein shock absorbers featured a special extrusion method. This allows the shock absorbers to achieve an extremely tight peak to valley tolerance level and consistent wall thickness. The flawless design provides extraordinary tube strength and well heat management which help it to increase the shock life.

3. Better Build :

Most of the traditional tubes available in the market are made of shock bodies cut from a piece of steel tubing. Then they were stamped internally with a compromised tolerance level.

On the other hand, Bilstein shock absorber bodies are formed using a seamless unique extrusion process. This technology provides more superior strength and high tolerance level without compromising anything. 

The shock body is also treated with a durable paint finish which they test in a 240-hour salt spray. After finishing the body they mated it with solid steel chrome plated and polished shaft. 

They also use the best quality sealed for the valving components. Moreover, they spend a great amount of time and attention to the details that allow them to manufacture a shock absorber that is close to a hand-built shock absorber.

How Many Miles Does Bilstein Shock Last?

Usually, shock absorbers do not require frequent replacing like filters or spark plugs but eventually with time they do wear out and have to be replaced. It is hard to say when to replace a shock absorber as it largely depends on what types of road you are using on a day to day basis. 

When you feel that the dumping of your shock absorbers are not good and the control is not balanced, you should check whether the shocks need to be changed or not. 

The build quality of Bilstein shock absorbers is really good. Traditional shock absorbers can last up to 40000-50000 miles depending on the way you handle and riding style and because of better build quality, you should expect a bit more miles on your Bilstein shock absorbers. 

Now you may ask I rode 70000 miles with my Bilstein shock how do I know that if it needs to be changed? Well, a good way to test this is a bounce test. 

If the shock absorber continues to gyrate one and two times more than usual when you are rocking and releasing the bumper or body, it means your shocks are in such an age when you need to replace them.
