What Is The Difference Between Shocks And Struts?

difference between shocks and struts

Did you see the difference between shocks and struts on your vehicle but don’t know why? Then you have come to the right place, where I will share all the important things related to shocks and struts. You will come to know what are parts of shock absorbers, do car’s have both shocks and struts? their role, position, etc. So let us read about this curious topic to understand the difference between shocks and struts quickly.

What’s The Difference Between Shocks And Struts?

The main difference between shocks and struts is the assembly and the setup which can be noticed by looking at it. Other than appearance many other things need to be learned. So to know about them let us move further where I will explain the differences one by one. Where you can know about does my car have shocks or struts when you see your vehicle next time? Let us see more about shocks vs struts in the following.

What Is Shocks?

Shocks are the type of simple suspension used in vehicles to absorb vibrations and bouncing. It works on a simple mechanism of the hydraulic pump which absorbs the pressure after the movement of the suspension in the up and down motion.

What Are Struts?

Struts are modified shock absorbers that help to retain the balance between the vehicle’s body and tire movement. They avoid the excessive bouncing of the vehicle and keep it stable with the help of the spring.

Difference Between Shocks And Struts

Here I have described the difference between shocks and struts in detail. You will understand the different parts and their role in the suspension system of shocks and struts.

  1. Coil Spring

The first difference between struts and shocks is the coil spring. Let us know what is the role of the Coilover spring in the struts shock suspension.


Shocks have a simple setup and consist of the piston, hydraulic fluid, and coil. This maintains the rebound of the vehicle after the dipping.


There is a coil spring on the struts which can be seen directly above the shock absorbers.

  1. Collar

The modification of the collar shocks and struts diagram can be noticed when seeing a wheel of the four-wheeler.


Shocks do not have any collar attachment on them.


There is collar support located on the structs which settle on the suspension spring and another part of the body of the vehicle.

  1. Rotating Nuts

Rotating nuts have an important role in height adjustment.


Shocks are constant or have a specific fixed height set up as per their construction.


In strut vs shock vs Coilover, there are rotating jam nuts that help them in adjusting the coil spring size to set a height at a particular custom adjustment.

  1. Adjustment Grooves

There are adjustment grooves, another difference between shocks and struts on a car and a bike suspension.


Shocks on the bike and bike are located in one place and do not have particular adjustment grooves.


Struts in the car and on the rear wheel of the bike have adjustment grooves with this the length of the suspension can be changed as per the grooves. Let us see is there a difference between shocks and struts, and other attachments to adjust the height.

  1. Knob

To adjust the piston there can be a knob inside the shocks vs struts vs springs attachments and suspensions of the vehicle.


A knob may be present inside the shocks assembly to adjust the compression of the piston.


The struts can come with or without knowing to adjust the movement of the piston inside the suspending assembly.

  1. Frame

The frame is an important thing that can affect the shocks and struts replacement cost very effectively.


The shocks frame has an assembly of the piston and coil with hydraulic fluid which compresses after the bouncing of the vehicle’s body


In struts what is the difference between shocks and struts is a supportive frame that is situated on the inner side of the car and external on the bikes. It adjusts according to the turning and shifting of the wheel and tires when moving up and down.

  1. Position

Let us see are struts in the front or back position are in the type of transport.


In bikes, the position of the shocks is on the front wheel, and some light four-wheelers can also have shocks with springs.


The struts assemble position is located on the rear tire in bikes, while in cars the struts can be found commonly.

Do I Need Struts Or Shocks?

Struts are designed to be much stronger than shocks since they are weight-bearing components. Additionally, they help dampen vehicle jolts and improve your vehicle’s steering and alignment.

Should I Replace Shocks With Struts?

Shocks and struts are the most important factor if you want your car to have a smooth, comfortable ride. Shocks and struts are reliable last much longer than many other parts in your car, but they’ll still need to be replaced with time. Shocks and struts should always be replaced at the same time.

Do You Have Both Struts And Shocks?

While shocks and struts work similarly, they are different systems. Typically, this means your car will have one or the other. Although it is important to note, some vehicles have both: shocks in the front and struts in the rear or vice versa.

How Much Do Struts Cost?

On average, expect to pay somewhere between $450 and $900 to replace a pair of struts. An individual strut assembly will cost about $150 to $300 so you’re looking at around $300 to $600 for parts alone. Labor alone will set you back about $150 to $300 for the pair.

How Long Do Struts Last On A Car?

On average, if your car has been “babied,” you can expect your shocks/struts to last about 10 years. If you have really used your car like a workhorse, 5 years is probably all you can expect. This means that for the average driver, 7 or 8 years is the maximum life expectancy of most shocks and struts.

How Do I Know If I Have Struts Or Shocks?

Look underneath your vehicle.

If your vehicle has shocks, you will likely find them mounted vertically behind the tires. In many cases, shocks will look like a spring or pump. Struts, on the other hand, are usually mounted horizontally and will appear as an extension of the wheel.


After reading the difference between shocks and struts you came to know different things about them. Now you have an idea about the suspensions used in cars and bikes. I told you how the adjustments can be done in the struts and shocks by adjusting the nuts, grooves, knobs, etc. In the future, you can choose the right suspensions for your vehicle as you now have complete knowledge of the difference between shocks and struts.
