Is a strut and shock the same thing?
When it comes to vehicle suspension systems, many car owners often wonder if struts and shocks are the same thing. While they serve similar purposes in ensuring a smooth and stable ride, they are not identical components. In this article, we’ll break down the differences between struts and shocks, their roles in your car’s suspension system, and why understanding these differences matters for your vehicle's maintenance.
What Are Shocks?
Shocks, short for shock absorbers, are components designed to control the movement of your car's springs and suspension. They help dampen the impact of bumps and uneven road surfaces, ensuring a smoother ride and better handling. Shocks are typically used in vehicles with separate suspension and steering systems.
Here are some key characteristics of shocks:
- They are standalone components that work alongside other suspension parts.
- Shocks do not support the weight of the vehicle; their primary role is to control spring oscillations.
- They are generally easier and less expensive to replace compared to struts.
What Are Struts?
Struts, on the other hand, are a more complex component that combines several functions into one unit. They are an integral part of the suspension system and also play a role in the vehicle's steering system. Struts are commonly found in modern vehicles with a MacPherson strut suspension design.
Here are some defining features of struts:
- They combine the shock absorber and other suspension components, such as the coil spring, into a single unit.
- Struts support the weight of the vehicle and help maintain proper alignment.
- Replacing struts is typically more labor-intensive and costly than replacing shocks.
Key Differences Between Struts and Shocks
While both struts and shocks serve to improve ride quality and vehicle stability, their differences lie in their design and function:
- Function: Shocks primarily dampen spring oscillations, while struts also provide structural support and play a role in steering.
- Complexity: Struts are more complex as they integrate multiple components, whereas shocks are simpler standalone parts.
- Cost: Struts are generally more expensive to replace due to their complexity and labor requirements.
Why Does It Matter?
Understanding the difference between struts and shocks is crucial for proper vehicle maintenance. If you notice issues like excessive bouncing, poor handling, or uneven tire wear, it’s important to know whether your car uses shocks, struts, or both. This knowledge can help you communicate effectively with your mechanic and ensure the right repairs are made.

Frequently Asked Questions
How do I know if my car needs shocks or struts?
Excessive bouncing when you hit a bump can be a signal that your shocks and struts aren't working effectively. Your vehicle should settle after hitting a bump and not continue to bounce. Worn shocks and struts aren't able to effectively absorb road impacts and soften the bump.
What happens if you don't fix struts?
Over time, shocks and struts can lose their ability to control weight transfer; this is what causes you to feel like you're not in control of your vehicle. This can be dangerous, especially if your tires lose contact with the pavement, making it difficult to control your vehicle in an emergency situation.
Do shocks replace struts?
Shocks, often referred to as shock absorbers, help manage and control your car's springs' movement. On the other hand, struts are more complex and serve as a structural part of the suspension, including the shock absorber, coil spring, and other components.
Can you drive with bad struts?
Struts on the front-end of your vehicle are also crucial for steering and alignment. Driving with a broken strut will be extremely uncomfortable for you and your passengers, and is unsafe in an emergency. It can also damage other components in your car.
What are the symptoms of a bad strut?
Signs Your Shocks or Struts Need to be Replaced
If your vehicle isn't driving smoothly and you notice any of these issues, there is undoubtedly a problem. Poor steering, quivering, vibrating, clunking, bumping, noises, tremors, the list goes on.
How much do new struts cost?
Shocks and struts replacement costs somewhere between $450 and $1,100. It's possible to remove just the shocks or the struts, but it may produce mixed results performance-wise. Common symptoms of failing shocks and struts include knocking sounds, bumpy rides, cupped tire wear pattern, and more.
Do I need both shocks and struts?
Shocks and struts should always be replaced in pairs (front axle or rear axle), and it's even better to replace the shocks/struts on all four wheels at one time. This helps maintain reliable handling and a consistent response on both sides of the vehicle.
How much does it cost to get struts replaced?
between $450 and $1,100
Shocks and struts replacement costs somewhere between $450 and $1,100. It's possible to remove just the shocks or the struts, but it may produce mixed results performance-wise. Common symptoms of failing shocks and struts include knocking sounds, bumpy rides, cupped tire wear pattern, and more.
How much does it cost to replace struts?
How Much Would It Cost to Replace Your Shocks and Struts? A typical shock and strut replacement can set you back anywhere between $450 and $1,100. However, keep in mind that this can vary depending on the type of vehicle suspension you have and your location.
Is a strut the same as a shock?
However, shocks and struts are two distinct parts with different functions. While both can help with your vehicle's ride and handling, these parts work in different ways. Shocks are individual components of the suspension system while struts are a major structural component of the chassis and suspension system.
