Shock Absorber Types for Car

Shock Absorber Types for Car

One of the essential parts of a car is its suspension system. This system includes various components, including shock absorbers. Shock absorbers are designed to absorb some of the impacts from bumpy roads and reduce both wears on tires and driver fatigue. There are three types of shock absorbers: gas-pressurized shocks, twin-tube shocks, and monotube shocks. Each type has its strengths and weaknesses that make them suitable for different driving conditions like off-road driving or long highway drives.

Monotube shocks, which use a single tube filled with hydraulic fluid to control resistance, are not standard because they don’t offer much inherent flexibility and can be difficult to maintain.

Gas-pressurized shocks are most commonly used on cars driven daily or for long trips where there’s ample opportunity to change the shock fluid.

Twin-tube shocks are most often found on trucks and SUVs where there’s less need to adjust the shock fluid or replace worn parts over time.


It was introduced back in 1950. It was a groundbreaking discovery back then. It is constructed of a single tube and a mostly gas-pressurized shock system was used. Two pistons that are working in the system distribute the shock into the tube by the road. Between the gas component and shock fluid, the pistons are placed.

The design is a tiresome process to implement what made it obsolete nowadays. Mercedes was the first company to embed this technology into an automobile.


This shock absorber goes by the name of “two-tube.” Consisting of two cylindrical tubes named Working Tube and Reserve Tube this device is used widely. A compression valve at the bottom converts the shock into heat energy. When the piston is pressurized, it goes up and down according to the conditions of the road. As the pistons move, the fluids also change the place into the small holes in the pistons. Valve dissipates the heat energy in the end.

Twin Tube’s idea was later adopted by many engineers and developed into many forms. Some popular modifications are Position-Sensitive Shock Absorber (PSD), Acceleration Sensitive Damping (ASD), Coliver. These devices are used interchangeably in different machines. Coliver is mostly used in scooters and motorcycles.


Gas-pressurized shocks are most commonly used on cars driven daily or for long trips where there’s ample opportunity to change the shock fluid. Gas pressurized shocks work by using nitrogen pressure to control the resistance in a damping fluid. The gas is contained within the shock’s body and compressed until it becomes pressurized, then released into a passage that returns to its original position where it can be re-compressed again.

What is Shock Absorber?

The shock absorber is an instrument designed to lessen the effect of abrupt shock by the extravagance of the shock energy. On cars, motorbikes or similar automobiles, this device is planted to help the frame absorb the coming from the wheels.

While driving, we may face holes on the roads or speed breakers, the spring helps to cope with the shock by contracting and expanding. It comes into the act to stabilize the mainframe and do it by constricting the movement of the springs.

Hydraulic is the most preferred shock absorber in the case of automobiles. This type of absorber formation is of a casing that built of two tubes, both telescoping each other. Because of their telescoping feature, when a spring wants to contract or expand they must both push the bottom points.

As the ends of the damper shock are built to be highly resistant, the spring movement is quickly restricted. On some of the new technologies, hydraulic suspension works the part of both spring and absorber. Aircraft shock absorber working principle to reduce the risk factors of landing. On some machines, elastic materials are used in the making.

They lay aside the vibration generated by the machine acting as the shock absorber. One great example is the cork we see on bottles. Another name for a Shock absorber is Damper damper shock.

How Much Does Shock Absorber Cost?

In modern days shock absorber is a built-in system for automobiles. But it wears out after a time. The technology’s price range can be $25-$350. The shock absorber reduces the risk emerging from automobiles. It made people more attached and encouraged the use of automation technologies.
