Difference Between Shocks and Struts
Difference Between Shocks and Struts
Shocks and struts: What's the difference?
The major difference between shocks and struts is that a strut is a structural part of the vehicles suspension system, whereas a shock is not.
Because of the frequent interchangeability of the phrases, we get this question rather regularly. In a car, a shock and a strut serve essentially the same purpose: to reduce the spring's motion and eliminate oscillation and bounce. Shocks and struts are distinct components that share a common purpose.
It is not possible to swap out struts for shocks or vice versa. Each vehicle will only ever have one type of suspension component, on the front or the rear. You may have both shocks and struts, but never both on the same end of your vehicle.
What is a Strut?
- A strut is an important part of a vehicle's steering system and has a significant impact on the alignment angles.
- It is usually the place where the camber and caster angles are adjusted.
- A strut also serves as an additional pivot point for the steering system and houses the coil spring.
- When replacing a strut, it is necessary to perform an alignment as well.
- The cost of struts is usually higher than that of shocks because they come with mounts, boots, and bump stops as part of their design.
What is a Shock?
To maintain tire traction, a vehicle needs a shock absorber. If you want your vehicle to stay riding smoothly, invest in high-quality shocks. The vehicle's components will see less wear and tear with a high-quality shock. Shocks often feature two eyelets at the top and bottom of the device, as well as a stem and an eyelet, or even a post.

Shocks and Struts?
People often call in saying they have been told they need shocks and struts. This is usually a friendly neighbor with a less than perfect knowledge of suspensions trying to be helpful. Because the terms are used interchangeably, customers often get confused as to which they need.
Can You Have a Shock and A Strut on the Same Vehicle?
To add to the confusion on shocks vs struts, yes you can have a strut and a shock on the same vehicle. A common configuration for vehicles is struts up front and shocks out back.
Can I Get a Complete Strut or Quick Strut for My Vehicle?
Buying a new strut assembly—including the strut, boot/bumpstop, mounts, and spring—is more economical than buying individual parts. Plus, it's far safer and will save you time and money on labor. A high-quality full strut is what you'll need, though. That means you're looking at Gabriel Ultra Ready Mount Strut, KYB Strut Plus, or Monroe Quick Strut if you go that route.
What are the parts of a strut assembly?
The individual parts of a strut assembly are as follows:
- Strut body or strut insert (strut inserts are commonly utilized in older vehicles; for more information, please refer to our Strut Insert FAQ)
- Bump stop and Boot (depending on the protected position of the strut, the boot may not always be necessary; for further details, please see our Shock Boot FAQ)
- Strut Upper Mount - Coil Spring - Spring Seat (which may be attached to the strut body)
