Shocks and struts are both important components of a car’s suspension system, but they serve different purposes. While shocks are responsible for dampening the movement of the springs, struts provide structural support for the suspension and also help to keep the tires in contact with the road. Understanding the difference between the two is crucial for maintaining the safety, handling, and ride comfort of your vehicle.
In this blog, we’ll take a closer look at the difference between shocks and struts, and explain why it’s important to keep them in good working condition.
What is a Car Strut?
A car strut is a part of a vehicle’s suspension system that plays a vital role in maintaining the stability and handling of the car. It is essentially a structural support for the suspension and helps to keep the tires in contact with the road. A strut is a combination of a spring and a shock absorber that is designed to provide both structural support and dampening of the spring’s movement.
The strut is typically located at the front of the vehicle and is an integral part of the MacPherson suspension system, which is commonly found in front-wheel drive vehicles. It is connected to the steering knuckle, the control arm, and the steering linkage, and is responsible for supporting the weight of the car and absorbing the impact of bumps and potholes on the road.
One of the key characteristics of a strut is that it is a sealed unit, meaning that the spring and shock absorber are not separate components. This makes it more compact and easier to install than a traditional shock absorber and spring setup. Additionally, the strut has a built-in steering pivot, which helps to improve the car’s handling and stability by allowing the wheels to move independently of each other.
When the car’s suspension system is in good condition, the struts help to provide a smooth and comfortable ride, by absorbing the impact of bumps and potholes on the road and maintaining the stability of the vehicle. However, if the struts wear out or become damaged, it can lead to poor handling, uneven tire wear, and a rough ride. It can also cause other suspension and steering components to wear out faster. For this reason, it is important to have the struts inspected and replaced if necessary, as part of regular maintenance.
How do Shocks and Struts work?
Shocks and struts are both important components of a vehicle’s suspension system. The main difference between the two is their function and design.
Shocks, also known as shock absorbers, are designed to dampen the movement of the springs in the suspension system. They work by using a piston inside a cylinder filled with oil or gas, to convert the kinetic energy of the spring’s movement into heat energy, which is then dissipated. This helps to reduce the amount of “bounce” or “rebound” that the springs produce, providing a smooth and stable ride.
Struts, on the other hand, are a combination of a spring and a shock absorber in one unit. They provide both structural support for the suspension and dampening of the spring’s movement. The strut is typically located at the front of the vehicle and is an integral part of the MacPherson suspension system, which is commonly found in front-wheel drive vehicles.
When a vehicle encounters a bump or pothole, the strut compresses, absorbing the impact and reducing the amount of movement transferred to the rest of the suspension. At the same time, the spring inside the strut expands, helping to restore the suspension to its original position.
Both shocks and struts play a crucial role in maintaining the stability, handling, and ride comfort of a vehicle. They help to keep the tires in contact with the road and absorb the impact of bumps and potholes to provide a smooth ride. As they are mechanical parts, they wear out over time and need to be replaced as part of regular maintenance to ensure the vehicle is running safely and efficiently.
Are Shocks and Struts the Same Thing?
No, shocks and struts are not the same thing. They are both important components of a vehicle’s suspension system, but they have different functions and designs.
Shocks, also known as shock absorbers, are designed to dampen the movement of the springs in the suspension system, by converting the kinetic energy of the spring’s movement into heat energy, which is then dissipated. This helps to reduce the amount of “bounce” or “rebound” that the springs produce, providing a smooth and stable ride.
Struts, on the other hand, are a combination of a spring and a shock absorber in one unit. They provide both structural support for the suspension and dampening of the spring’s movement. Struts are typically located at the front of the vehicle and are an integral part of the MacPherson suspension system, which is commonly found in front-wheel drive vehicles.
In summary, shocks and struts are different components of the suspension system that perform different functions, shocks are used to absorb the energy of the spring’s movement and struts are used to support the suspension and also to absorb the energy of the spring’s movement.
What’s the Difference Between Shocks and Struts?
Struts and shocks are both important components of a vehicle’s suspension system, but they have distinct differences in terms of their function, design, and location.
Function: Shocks, also known as shock absorbers, are designed to dampen the movement of the springs in the suspension system. They convert the kinetic energy of the spring’s movement into heat energy, which is then dissipated, helping to reduce the amount of “bounce” or “rebound” that the springs produce, providing a smooth and stable ride.
Struts, on the other hand, are a combination of a spring and a shock absorber in one unit. They provide both structural support for the suspension and dampening of the spring’s movement. They are typically located at the front of the vehicle and are an integral part of the MacPherson suspension system, which is commonly found in front-wheel drive vehicles.
Design: Shocks are typically cylindrical in shape and have a piston rod that extends out of one end. They are often filled with oil or gas and have a valve regulating the piston rod’s movement.
Struts have a more complex design that includes a spring coil, a strut mount, and a piston rod. The spring coil is located around the exterior of the strut, and the strut mount is located at the top of the strut, connecting it to the vehicle’s body. The piston rod is located inside the strut and is connected to the suspension’s control arm.
Location: Shocks are located at all four corners of the vehicle, usually mounted at the rear of the vehicle. They absorb the vertical movement of the wheels and help to keep them in contact with the road.
Struts are usually located at the front of the vehicle, and they provide support to the steering and suspension system, they also help to keep the wheels in contact with the road.
In summary, shocks and struts are different components of the suspension system that perform different functions, shocks are used to absorb the energy of the spring’s movement and struts are used to support the suspension and also to absorb the energy of the spring’s movement. Struts are typically located at the front of the vehicle and shocks are located at all four corners of the vehicle.
Does your vehicle need new Shocks or Struts?
There are several signs that indicate that your vehicle may need new shocks or struts. These include:
- Uneven tire wear: If the shocks or struts are worn out, they will not be able to keep the tires in proper contact with the road. This can result in uneven tire wear, which can be a sign that the shocks or struts need to be replaced.
- Rough ride: Worn-out shocks or struts can cause the vehicle to ride more roughly, resulting in a bouncy or unstable ride.
- Nose dive: When braking, if the front of the vehicle dips down excessively, it could be a sign that the struts are worn out.
- Vehicle sways: If the vehicle sways or leans when taking turns, it could be a sign that the shocks or struts need to be replaced.
