Have you ever driven a car with bad or worn-out dampers? If you did so, you already know terrible it feels. The car vibrates a lot, handling is not smooth, you tend to jump on the bumps.

All these problems are instantly eliminated by installing shock absorber. Shock absorber is placed in a vital position. It is the bridge between the suspension and the vehicle body.

Shock Absorber – Technical Overview

The main difference between Bilstein 5100 and 4600 Shock Absorber is that 4600 Series uses a mono tube design, while the 5100 Series is a twin-tube shock absorber. The Bilstein 4600 5100 shocks can be paired with Eibach Pro kits for improved handling and performance.

The biggest difference between the 2 types of shocks is the height. If you have a truck with a higher bed, then you should buy 4600 shocks. If you have a truck that is high off the ground, then 5100 shocks are what you want.

The Bilstein 4600 shock absorber uses a mono tube design. It is made of high tensile strength steel, zinc plated and finished with a durable epoxy powder coat to resist corrosion.

The Bilstein 5100 shock absorber uses an internal floating piston (IFP) technology for enhanced damping control. The 4600 Series does not have this technology. It is manufactured with an advanced steel alloy, the 5100 Series is zinc plated then finished with a durable epoxy powder coat to resist corrosion.

The 4600 Series will typically feature shock absorbers that are pre-set for optimum road handling when paired with lowering springs. The 5100 Series comes in various damping force settings, allowing you to adjust the shock absorber for your desired level of performance.


There’s plenty of options for dampers. You can easily find over hundreds of after market shocks. They vary in size, compatibility, type and many more. Of them, type is a core concern as it decides how your chosen damper will operate.
Mono tube, twin tube, strut based, telescopic, tri tube and more, options are many. You have to settle with one that suits your vehicle the most.

Generally, we see the mono tube a lot. It has the perfect balance of technology and specification. Both of these shock absorbers by Bilstein are mono tube. Mono tube is very simple in action. It is somewhat like a pump. With a free-flowing piston inside, it absorbs impact and pumps it out as heat energy. This activity might seem simple at first but requires tough built quality. And as per the buyers, both 4600 and 5100 comes with the genuine power.

Bilstein was the first company that came out with the idea of pressurized gas technology. So, no doubt they would be the best in that class.

Bilstein dampers have patented digressive valving with vulcanized rubber bushing. To ensure that the don’t lack in quality they only manufacture in Germany or USA. These shocks fits easily and they are crafted by most skillful makers in the industry. Either on or off roads, with this quality in hand, you are good to go.

Suitable Vehicle

The 4600 series is a very balanced damper. It accommodates SUVs, Jeeps and light truck. Al though it is good to go for both on and off road, it is mostly used on road by the vehicle users, it has tremendous weight lifting capacity.

5100 series is rather extreme. It goes off road and on road in extreme of weathers. It adds height to your car, gives it a more lifted look. This shock is the perfect shock for lifted trucks and SUVs.


Price is an important segment when choosing shock absorber as it varies from person to person. Shocks are found in rather wide range. This is why you need to fix the amount of money you want to spend in your shock investment.
