Things to keep in Mind
- Look for the technology used and the features provided. There may be an upgraded model of the same product with improved technology and features.
- Be sure of what height you want. Choose the shocks which can be easily adjusted to your required size. This will make the installation easier and ultimately give you the preferred outcome.
- Look for the durability of the shocks. Buying expensive shocks which might rust over time will do you no good. So look for the materials used in the build.
- Find out the road conditions of your average routes. Different shocks are built to satisfy different needs and road surfaces. A better idea of the routes and requirements will help make a good decision.
Type of Shock
You go into the market and get your head around the different shock absorbers you see. Based on the tube, you can divide them into two categories, like monotube or twin-tube.
5125 and 5100 are both excellent products from a great company like Bilstein. And they are both monotube dampers which is eventually the latest technology.
Function
Dampers ensure you enjoy riding by eliminating any vibration and impact generated while driving. Traditionally companies used telescopic shocks, and later on, they started using the strut-based system.
But nowadays, most of the shocks are spring seat powered, and these two are no different. One significant benefit you get is that the spring works both as the suspension of the car and the dampener.
Material & Lifespan
Being of the same company, they don’t differ much in building material or lifespan. It’s the application that is likely to vary. However, both products are made of steel with a zinc coating outside that has the power to resist any rust. They both have a 45mm piston; on average, they last for five years/ 80,000 km.
Installation
They have their core difference in their applicability. The 5125 is designed for more specific and modified vehicles. As the shock is self-adjustable, it is easier to install because it would fit its own. However, 5100 is not a self-adjustable shock, and you need to instruct according to your height preference.
Price
They already have so many things in common, as you can see. It is not difficult to guess that they have a reasonably similar price. The company thought of the consumers who love to drive a customized vehicle and produced a damper to meet their needs. You have to give credit to the Bilstein authority for not making any discrimination.
Our Observation
The main difference between Bilstein 5125 and 5100 shock absorbers is the installation and technology. The 5125 is a self-adjustable shock, making it easier to install and perfect for modified vehicles. On the other hand, 5100 comes with three preload-adjustable settings and might be a bit difficult to install. Also, it uses the latest technology, making it a better choice if you want an upgrade.
How Long Do These Shocks Last?
They can last up to 5 years, depending on the use. The shocks are made to run 80,000 km in their lifetime.
How Good Is the Brand?
They have provided the best value for money service since 1954. They are among the leaders in the industry when it comes to innovation and performance. Monotube dampers, air suspension, and electronic suspension systems dominate all categories.
Can I Install the Shocks Myself?
It is advised to install the shocks with the help of an expert. Any installation error might cause serious injury or even a threat to life. So for installation or repair, it is advised to contact a local dealer or an expert.
Which Way Should I Mount My Shock?
The mounting orientation depends on the model. The upper and lower mounts may be the same or different. An easy way to fix this is to ensure the logos remain right-side-up when the shock is installed. This will ensure that the shocks are mounted in the correct position.
Final Verdict
These two products perform well in all road conditions and can be installed on vehicles used for various purposes. It is up to you to determine your vehicle’s requirements and choose one of the above. Both products provide excellent performance and are among the best in their particular segments.
I hope we have helped you make your decision. Whichever shock you choose, always remember to ride safely and wear seatbelts. Want to read more about shock absorbers? Please check the Bilstein 5100 vs 5160 comparisons.
