What is the Difference Between Shocks and Struts?

The next time you enjoy a smooth ride in your car, think of the excellent work the shocks and struts are doing. While you may not pay much attention to these two components in your vehicle, they make driving easy on rough surfaces, bumps, and potholes. Even when the roads appear smooth, which none actually is, the shocks and struts make it feel even.

What are Shocks and Struts?

They have similarities that help your vehicle's suspension system, handling, and ride but work differently. Their role is integral to your safety and comfort while driving. The key difference is in the design. But here is a breakdown of the differences between the two.


They are also called shock absorbers and are hydraulic components of the suspension system. Shocks minimize the impact and rebound of your vehicle's spring movements by absorbing the jolts on damaged or uneven roads. There are three types, namely,

  • Dual shock
  • Mono-tube shock absorber
  • Coil-over shocks

Shocks ensure that tires remain in contact with the road at all times, smoothing out rough areas on the road. Without shock absorbers, your car would bounce on the road with erratic vibrations, making your ride bumpy and unbearable.


Struts are part of the suspension's structural setup and are common in the front end of front-wheel-drive vehicles. Struts may be smaller than shocks but integrate different suspension components into one compact assembly. These include the coil spring, spring seats, strut bearing, shock absorbers, and the steering knuckle. Generally, struts are mounted to the steering knuckle with the spring's top set to support the body.

Do You Need Shocks or Struts in your Vehicle?

Every wheel on our car has either a strut or shock. However, not all cars have struts. Some may use separate springs and shocks instead od struts. If you are unsure, look underneath your vehicle or ask a technician.
Shock and struts wear out over time, usually after 30,000 to 75,000 miles. However, replace them when needed. Our experts are waiting for you. Call or visit Foreign Auto Services Inc in Chantilly, VA today if you need shocks or strut replacement.
