Shock absorbers and shin guards

Shock absorbers and struts are key suspension components responsible for damping shocks, improving vehicle stability, and ensuring safety while driving. Thanks to their operation, the vehicle's suspension effectively adapts to road irregularities, guaranteeing smooth and comfortable handling. In the Global Parts automotive store, you will find a wide selection of used car parts, including shock absorbers and struts, ideal for brands such as BMW, Audi, Mercedes, Volkswagen, Mini, and many others.

How do shock absorbers work in a modern car suspension?

A car shock absorber is a hydraulic or gas-oil component whose main task is controlling the movement of the suspension spring. In practice, this means that the shock absorber limits excessive wheel rebound after hitting a bump. In a typical passenger car, a shock absorber performs up to several thousand work cycles per minute when driving on uneven surfaces. Modern vehicle suspension consists of several cooperating elements:

• shock absorber;
• suspension spring;
• control arm;
• stabilizer;
• McPherson strut bearing. Many popular designs use a McPherson strut, which combines the shock absorber and spring into one unit. This solution is used in models such as the BMW 3 Series E90, BMW E87, BMW E60, or Volkswagen Golf V. This makes the construction lighter while ensuring good vehicle stability. For example:
• BMW E90 rear shock absorbers are mainly responsible for vehicle stability during acceleration and cornering;
• BMW E60 front shock absorbers work within the McPherson strut and are responsible for damping most irregularities;
• Golf 5 rear shock absorbers stabilize the rear torsion beam and influence wheel grip.

What functions do shock absorbers and struts perform?

Shock absorbers and struts play key roles in the suspension system:

• Vibration damping – Shock absorbers reduce shocks and vibrations generated by road irregularities, increasing driving comfort.
• Vehicle stabilization – Struts, along with shock absorbers, keep the wheels in constant contact with the road surface, improving stability and traction.
• Suspension protection – They reduce the loads acting on other suspension components, extending their service life.

Construction and purpose of shock absorbers and struts

Shock absorbers and struts are suspension components mounted at the wheels, designed to control spring movement and maintain stable tire contact with the road. A typical set may include the shock absorber body, piston rod, mounting points, and in the case of a strut, a point of cooperation with the spring and upper bearing. A strut usually refers to the part of the suspension column that carries loads and guides the wheel in the correct position.

Most commonly used types of shock absorbers – construction comparison

Several basic types of shock absorbers are used in modern cars. They differ in construction, damping method, and operating characteristics.

Comparison of shock absorber types and fitting data

Type / variant	Construction	Application	What to check before purchase
Oil	Piston working in an oil chamber	Focused on smooth damping and ride comfort	OEM number, working length, mounting type, vehicle placement
Gas-oil	Oil and pressurized gas in one construction	Better body control during faster driving and higher loads	Mounting side, suspension version, mounting diameter, replacement numbers
McPherson strut / strut	Unit cooperating with a spring and upper mount	Front axle in many car models	Body compatibility, mounting points, equipment presence, OEM part number

In many premium models – e.g., BMW E60 front shock absorbers – high-pressure gas shock absorbers are used, which provide more precise handling at higher speeds. In compact models, such as Golf 5 shock absorbers, classic gas-oil shock absorbers are often found, providing a good compromise between comfort and driving stability.

Vibration damping function and cooperation with other suspension elements

The shock absorber is used to extinguish spring movement after suspension compression, preventing the body from excessive swaying. In practice, it works with control arms and ball joints, stabilizers, clamps, and bushings, as well as other parts from the Suspension and steering system department. When choosing a component such as a BMW E60 front shock absorber, it is worth comparing the OEM number, mounting side, and suspension version.

Why is it worth taking care of shock absorbers and struts?

Wear or damage to shock absorbers and struts can lead to suspension problems and reduced driving comfort and safety. Typical symptoms of failure include:

• Noise while driving – Knocking or squeaking may indicate worn shock absorbers or struts.
• Excessive vehicle swaying – Damaged shock absorbers can cause vehicle instability during cornering and braking.
• Uneven tire wear – Problems with shock absorbers can affect the incorrect distribution of load on the wheels.
• Oil leaks – Leaks from shock absorbers indicate their damage. If replacement is needed, at Global Parts you will find suitable used car parts that will restore full functionality to your suspension system.

How to choose shock absorbers for a specific car model?

Choosing a shock absorber for a car is based primarily on the technical parameters of the suspension and the vehicle's axle construction. Car manufacturers design shock absorbers to work with specific springs and suspension geometry. When matching shock absorbers, the following are taken into account:

• suspension type (McPherson, multi-link, torsion beam);
• shock absorber working length;
• piston diameter;
• damping characteristics. In practice, this means that shock absorbers for one model may come in several versions. For example:
• BMW E60 shock absorbers are available in standard and sports versions;
• BMW E60 front shock absorbers differ in construction from the rear ones;
• BMW E87 shock absorbers work in a McPherson strut at the front and a separate shock absorber at the rear;
• Golf 5 rear shock absorbers work with a torsion beam and a spring placed next to the shock absorber. This allows for precise matching of parts to the specific vehicle configuration, which translates into stability and driving comfort.

Selection by OEM number, axle, and cooperating elements

The OEM number is the manufacturer's designation that allows comparing part compatibility with a specific car version, axle, and mounting method. When completing a repair, it is also good to check the upper mounts, covers, bump stops, and shock absorber and strut mounts, as these elements affect the correct installation and operation of the strut. If a component such as a BMW E60 shock absorber is sought, the OEM part number, replacement numbers, and vehicle placement must be verified.

How to choose the right shock absorbers and struts?

When choosing shock absorbers and struts, pay attention to several key aspects:

• Matching the vehicle model – Every suspension system requires specific technical parameters. In the Global Parts automotive store, you will find shock absorbers and struts perfectly matched to BMW, Audi, Mercedes, Volkswagen, Mini, and others.
• Technical condition – Used elements should be free from leaks, corrosion, and mechanical damage.
• Shock absorber type – Choose the appropriate type (oil, gas, or gas-oil) according to your vehicle's construction. In practice, this means matching the shock absorber to the specific suspension construction and vehicle axle. In many popular car models, a McPherson strut is used at the front and a separate shock absorber at the rear. For example, BMW E60 front shock absorbers are responsible for damping most vibrations while driving, while BMW E90 rear shock absorbers stabilize the rear axle and improve vehicle handling in corners. The shock absorber is an intensively working element – while driving, it can perform hundreds of work cycles per kilometer. Therefore, it is important to maintain correct damping parameters and proper construction tightness. In models such as BMW E87 shock absorbers or BMW E60 shock absorbers, the proper technical condition of the shock absorber has a direct impact on suspension stability and driving comfort. Oil shock absorbers provide more comfortable operating characteristics, while gas-oil shock absorbers improve vehicle stability at higher speeds. In many modern cars, the latter construction is used, e.g., in models such as the BMW E60 or Volkswagen Golf V, where Golf 5 shock absorbers are responsible for maintaining body stability and proper wheel contact with the road surface.

Practical tips for installation and part verification

The McPherson strut is a unit where the shock absorber works with the spring, upper bearing, and mounts, so before installation, you need to check the completeness of the equipment. After replacement, it is worth checking the condition of adjacent elements, such as suspension replacement kits, covers, and bump stops, as well as suspension geometry. For parts such as Audi A4 B7 shock absorbers, it is important to compare the OEM number, body version, and vehicle placement.

Why is it worth choosing used shock absorbers and struts?

Used car parts, such as Shock absorbers and struts, are an economical solution that allows for savings while maintaining high quality. By choosing used suspension elements, you gain:

• Lower costs – Used components are significantly cheaper than new ones but offer equally high quality.
• Ecology – Recycling parts supports environmental protection and reduces waste.
• Wide offer – In our store, you will find used shock absorbers and struts for the most popular car brands. For many popular car models, the cost of new suspension elements can be relatively high, especially in mid-range and premium vehicles. Therefore, used parts are a practical solution allowing for reduced repair costs while maintaining proper suspension operating parameters. This applies, among others, to models such as BMW E60 shock absorbers, BMW E87 shock absorbers, Golf 5 shock absorbers, or Golf 5 rear shock absorbers, which are among the most frequently sought suspension elements on the car parts market. Thanks to wide availability, it is possible to match appropriate components for both the front and rear axles of the vehicle.

How to take care of shock absorbers and struts?

To ensure shock absorbers and struts work reliably for a long time, it is worth following a few rules:

• Regular inspections – Check the condition of shock absorbers and struts during periodic technical inspections.
• Avoid overloading the vehicle – Excessive load can lead to faster wear of suspension elements.
• Replace damaged elements on time – Worn shock absorbers and struts should be immediately replaced with functional ones to avoid further suspension problems. Shock absorbers belong to the most intensively working suspension elements – while driving, they perform hundreds of damping cycles on every kilometer of the road. Their proper operation affects not only driving comfort but also vehicle stability and even wheel contact with the road surface. In cars such as the BMW E60, BMW E87, or Volkswagen Golf V, shock absorbers work with other suspension elements, including springs, control arms, and stabilizers. Thanks to this, the entire suspension system can effectively damp road irregularities and ensure predictable vehicle handling.
