A vehicle's suspension system plays two major roles. It ensures a comfortable driving experience for the passengers and assists in the handling of the vehicle. When it comes to a smooth driving experience, shock absorbers and struts are the parts that have the most integral part to play. Any problems in the suspension system will put a serious dent in the effortless handling of a vehicle, which can sometimes put you and other drivers on the road at serious risk.
Depending on the factory configuration, your car can either have a shock or strut installed on the wheels. It is important to know that a shock absorber and a strut cannot be interchanged with one another while replacing them. Therefore, before replacing any defective parts in your suspension system, it is important to know what mechanism is used in your vehicle. If you have any questions about our replacement shocks or struts, feel free to let us know; our support team is at hand to help you out.

Shock absorbers and struts are often misconstrued for one another, due to the similarity in their appearances. They are basically employed for the same function, with some minor differences in their construction and design. Below, we have elaborated on the basic concepts of a shock absorber and strut, and how to tell them apart from each other. Here are some of our articles and related videos on repairing suspension parts.
Struts vs Shocks
The shock absorber is a dampener which absorbs the vibrations caused in the vehicle by converting the car's kinetic energy into heat energy. They are also responsible for keeping the tires in contact with the road while providing an optimal ride quality and safety. While cornering or negotiating sharp turns, the shock absorber works to prevent an excessive vehicle body lean or roll in any direction. In addition to stabilizing the vehicle, the shock absorbers also contribute to minimizing the tire wear and protect the overall suspension system, as well.
The shock absorber or shock is located between the car's frame and wheels. The shock absorber mount is attached to the piston rod which is connected to a piston. The piston is fitted inside a cylinder filled with hydraulic fluid. This simple mechanism dampens most vibration in the vehicle. When the shock receives an impact due to a bump, it compresses the fluid, exerting pressure inside it. A piston attached to the top of the cylinder moves up and down, based on the suspension movement. As the piston moves, the fluid is forced out through orifices, which along with the check-valves, limit the amount of fluid that flows through the piston. This slows down the piston movement and thereby, reduces the spring movement, as well. This ensures that the driving experience is bump-free.
There are two common kinds of shocks used in vehicles: twin-tube and mono-tube shock absorbers, out of which the twin-tube shock absorbers are the most common types used in vehicles. The twin-tube shock uses compression and expansion to accomplish its function. During the compression phase, the shock receives vibrations and pushes the piston that is in contact with the hydraulic fluid downwards, resulting in the compression of the hydraulic fluid. This compression results in the conversion of the kinetic energy into heat energy. In a hydraulic system, for every compression that takes place, it is often followed by an equivalent expansion process. The same is true of the shock, as well. During the expansion phase of the twin-tube shock, the piston moves upwards and the fluid gets transferred to a chamber above the piston. On the other hand, the mono-tube shock comprises a single pressure tube and two pistons called the working and dividing pistons. The pressure tube consists of both the hydraulic fluid and air which are separated by the pistons.
Some shock absorbers allow drivers to manually adjust the valves in the shock absorber for better control of the ride, it can also be achieved remotely in some high-end vehicles. Often, it is the coilover shocks that are confused with struts due to their similar designs.
Struts are one of the active components of the suspension system that absorb the irregularities on roads to ensure a smooth driving experience for the passengers. While this is also the basic purpose of the shock absorbers, the struts form a structural part of the suspension system. The struts stabilize the suspension system while adding increased tension and support to it, along with other suspension components. Struts are connected to the steering rack, replacing the upper control arm. Internally, the design and function of the strut is similar to that of a shock absorber. MacPherson struts are the most common types of struts used in automobiles. Most MacPherson struts have a coil spring wound around them like the coilover shock absorbers.
The strut usually has an upper strut mount connected to its one end while a bump stop is attached to the lower end. The bump stop prevents metal-to-metal contact of the strut with the other suspension components, while also adding to the shock absorbing ability of the strut, when it reaches its limit.
In the case there is a defect or irregularity in the bump stop, strut mount or the shock section, they can usually be replaced individually to fix the problem. After installing the new part, all these three components need to be aligned with one another to ensure their proper functioning. In some strut designs, the strut mount, bump stop and the strut come together as a single unit. These types of struts are called loaded struts. In case of the failure of a loaded strut, the entire assembly needs to be replaced. While replacing these struts, care should be taken since the coil spring needs to be compressed. Apart from loaded struts, there is also another category of struts that come with replaceable cartridges. These struts can be replaced easily without having to remove the strut from the vehicle. During the replacement of any kind of strut, the wheel alignment also needs to be checked.
If you remove a shock absorber, the vehicle can still run with the rest of the suspension system, but with severe vibration and minimal control. However, in case of struts, since they form the structural part of the suspension, the vehicle cannot run if they are removed.
Common Problems with Struts and Shocks & their Consequences
Whether it is a strut or a shock, they suffer from almost similar problems. One of the most common problems with a hydraulic shock or strut is leakage of the fluid from the cylinder. This can result in diminished dampening performance from the shocks and struts. Other problems with the struts include worn-out springs and hardened bump stops. Some of the common symptoms of bad struts/shocks include shifting of the car to one side while cornering, or aggressive vibration of the vehicle, especially when driving at high speeds. Struts are generally priced higher than shocks, and also tend to have higher labor and repair costs than shocks.
Air Struts and Shocks
Air suspension systems have now been adapted by many automakers due to their flexibility in suspension settings. These are superior to traditional suspension systems since they allow for adjustments in the ride height and provide an exceptional ride quality. The air suspension system relies on an air compressor to adjust the ride height to the required level. In an air suspension system, the air struts are generally called the air bags. One of the most common problems with air struts is the air leakage, which can result in poor dampening effects. The air struts can also fail due to a number of factors such as aging, wet rust or moisture. It is important to replace air struts meticulously, since any mishaps in installation can result in a premature failure of the system. You can restore the performance of your air suspension system by replacing faulty air struts or air compressors with new replacements from BuyAutoParts.com.

Let's start here with an overview of strut assembly. A strut is basically a shock absorber mounted inside the coil spring. It is a suspension component that is designed to resist compression, which combines the function of the coil spring, spring seat, shock absorber, strut bearing and steering knuckle to support the suspension system. The strut provides shock absorption and structural support for the suspension of the vehicle while driving on rough roads. A strut can be found at the midpoint of the fender wall.
Most vehicles have four struts, two each in the front and rear. Struts absorb the stress of the car and keep the wheels in position during rough road conditions. A strut is linked to a shock absorber and spring, steering link, car frame and lower control arm. A worn out strut reduces the tire's ability to grip the road. If you have any issues with your struts, you should replace them as soon as possible. Buy Auto Parts stocks a wide range of struts for every car make and model.
