What is the difference between shocks and struts?
Shocks and struts are often referred to interchangeably as they perform the same function, however, they differ in suspension system design. When you drive over a speed bump, pothole, or other rough roads, you’ll be thankful when the shocks and struts on your vehicle are working well.
What is the difference between a shock absorber and a suspension spring?
A shock-absorber is an element (usually a slider) which attenuated energy and reduces acceleration along it's longitudinal axis. It does this by the help of a spring and a damper. The spring is used to resist compression force and the damper is used to dissipate energy. A suspension spring is just that.
What happens if you don't have shock absorbers on a motorcycle?
In absence of shock absorbers, a shock will induce a persisting oscillation which will make the ride quite uncomfortable and irritating at the same time.
What is the difference between a coil spring and struts?
There are some vehicles that utilize a single strut with a separate coil spring. Struts are typically mounted to a steering knuckle, with the top of the ‘spring’ installed to support the body. Struts are much smaller than shock absorbers, which is a primary reason why they are often used in vehicles with compressed suspension travel.

Are shocks suspension?
Shocks are part of the suspension system, but they are not essential in order to operate your car or truck. Granted, without shocks, you won't have the most comfortable ride, but your vehicle is still able to function.
How much does it cost to change shocks?
Shock Replacement Cost The average total cost to replace a pair of shocks will run about $250 to $580. An individual shock absorber will cost around $50 to $140 so parts alone will set you back between $100 and $280. A couple hours of labor to do the job is an additional $150 to $300.
How can you tell when you need new shocks?

The most obvious sign of a problem with your shocks or struts is that your car is giving you a much more uncomfortable ride than normal. ... Steering problems. ... Braking problems. ... Fluid leaks. ... Unusual tire tread wear. ... Mileage.
Is absorber and suspension the same?
Suspension spring is known as the shock absorber(in a suspension system of a vehicle) since it absorbs the shock loads from the ground. Since the spring tends to continue oscillating a damper is used to arrest that motion.
Should I replace all 4 shocks at the same time?
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 long do car shocks last?
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.
What do worn shocks sound like?
Unusual noises – When shocks and struts are worn out you may hear a clunking or knocking sound. This sound is caused by metal-to-metal contact when the shock or strut bottoms out when hitting a bump. In addition, these noises could be a result in worn shock or strut mounting components.

Do shock absorbers affect suspension?
Increased wear on other suspension parts – Worn shocks and struts can have a negative effect on related steering, braking, and suspension components. As the shocks or struts wear, they allow more suspension movement, meaning that other steering, braking and suspension components can suffer the same effects.
Do I have shocks or struts?
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.
What's the difference between suspension spring and shock absorber?
Springs are designed to support the vehicle and cushion the ride when the vehicle strikes objects in the road. The shock absorbers (also known as struts) limit the vertical travel or motion from the springs along with absorbing or soaking up the impact from road obstructions.
Can I replace shocks myself?
If you need to replace your car's shock absorbers but don't want to pay an expensive mechanic's fee, you can do so on your own with a little effort. Shocks are essential to a car's performance, giving it a smooth and even ride. Over time, however, the vehicle's suspensions become worn out.
How much should it cost to replace shocks and struts?
between $450 and $1,100A typical shock and strut replacement can set you back anywhere between $450 and $1,100 on parts and labor combined. An individual shock and strut assembly costs around $150 to $900, while estimated labor costs for replacing a shock and strut assembly can range anywhere from $150 to $300 per assembly.
How long does it take to change shocks?
around one to two hoursTypically, it takes around one to two hours to change struts, according to most professional mechanics. Even if you decide to replace them on your own, the estimated time is the same as long as you have previous mechanical skills and follow the process correctly.
Will new shocks improve my ride?
A thorough inspection should uncover what parts, if any, actually need replacement. The springs in your vehicle's suspension do most of the shock damping. The shocks and struts improve the ride and reduce the bouncing caused by springs compressing and releasing so you don't go boing-boing down the road.
What is the role of shock absorber and suspension spring?
Answered 5 years ago. Shock absorber and suspension spring has different roles in the suspension system of a vehicle. When a pothole or bump comes under the wheel, suspension spring allows the vertical movement of the wheel and to adjust accordingly so that the passenger floor will remain at level. But when bump/pothole pasess as a result ...
What is a suspension spring?
A suspension spring (compression spring, leaf spring, air spring etc) is that element of suspension system which takes the shocks from the road surface through suspension links and later the shocks are dampened with the help of shock absorbers.
What is a shock absorber?
Continue Reading. A shock absorber is a dampening device which dampens the oscillations produced due to shocks. In absence of shock absorbers, a shock will induce a persisting oscillation which will make the ride quite uncomfortable and irritating at the same time.
What is a strut in a car?
A Strut is essentially a shock absorber and a spring fitted into one unit. On some cars, the damper (or technically the shock absorber) is seperate from the spring. If the Spring and shock are mounted together as a single unit, it is called a strut.
Why is a shock absorber important?
The shock absorber hence helps to avoid this by dissipating the energy of the spring as heat energy.
What is an automobile shock absorber?
An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). [1]One design consideration, when designing or choosing a shock absorber, is where that energy will go.
Do shock absorbers work on motorcycles?
Shock Absorbers in motorcycles come with a combination of the spring and the shock absorber also. If you find oil leakage from the shock absorber, you should change them.
Role of Shocks and Struts
A key part of your vehicle's suspension system, shocks and struts help keep your vehicle's tires in contact with the road. Why is this so important? If your car doesn’t maintain firm contact with the road, steering, handling and braking can all be affected. Quality ride control products perform many vital functions:
Difference Between Shocks and Struts
Many times, you’ll hear people refer to shocks and struts interchangeably. 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.
What Shocks Do
Despite what many people think, conventional shock absorbers do not support vehicle weight. Instead, the primary purpose of the shock absorber is to control spring and suspension movement. This is accomplished by turning the kinetic energy of suspension movement into thermal energy, or heat energy, to be dissipated through the hydraulic fluid.
Shock Components
Shock absorbers are basically oil pumps. A piston is attached to the end of the piston rod and works against hydraulic fluid in the pressure tube. As the suspension travels up and down, the hydraulic fluid is forced through the orifices inside the piston. However, these orifices let only a small amount of fluid through the piston.
What Struts Do
The strut is a common damper type used on many of today's independent suspension, front wheel drive vehicles as well as some rear wheel drive vehicles.
Strut Components
Typically, struts consist of a strut housing to provide rigid structural support for the assembly and a damping unit within the strut housing to control spring and suspension movement. On most struts, the bottom of the body attaches to the steering knuckle, which in turn connects to a lower control arm through a lower ball joint.
Does My Vehicle Have Shocks or Struts?
Every wheel on your vehicle has either a shock or strut. However, your vehicle could have shocks on the front and struts on the back or some other configuration. The key takeaway is that each wheel has some sort of ride control part.
What are the shocks and struts on a car?
While these two vehicle components are often discussed together, they are individual parts that provide a vital service for keeping your vehicle sturdy and safe.
What is a coil over shock?
Coil-Over Shocks: Vehicles with shock absorbers installed on the front are typically called coil over shocks — they have a shock absorb er that is ‘covered’ by a coil spring.
What are the parts of a vehicle suspension system?
Each vehicle driving down the road today has a vehicle suspension system comprised of multiple individual parts — including shock absorbers (or struts) and springs. Springs are designed to support the vehicle and cushion the ride when the vehicle strikes objects in the road. The shock absorbers (also known as struts) limit ...
What is a strut on a steering knuckle?
Struts are typically mounted to a steering knuckle, with the top of the ‘spring’ installed to support the body. Struts are much smaller than shock absorbers, which is a primary reason why they are often used in vehicles with compressed suspension travel.
Do all vehicles have shocks?
All vehicles will use a shock or a strut on each of the four corners. Several use struts on the front with a shock absorber in the rear. Struts are used on vehicles without an upper control arm and connect to the knuckle while vehicles with an upper and lower control arm (independent suspension) or a solid axle (on the rear) use shock absorbers.
Do you replace struts in pairs?
Shocks and struts should always be replaced in pairs (on the same axle at the least) and the vehicle should have a professional suspension alignment completed to ensure the tires, steering, and complete suspension system is aligned straight. Struts. Shock Absorbers. Shocks. Home.
Why do you need shocks on a car?
These springs absorb some of the jolts you might feel from uneven or damaged roads. By softening the impact from rough roads and rocky terrain, shocks can help you maintain better control over your vehicle, resulting in a smoother, more comfortable driving experience.
Why are shocks and struts important?
But when you drive over a pothole or bump in the road, you will be glad you have them! Even when the road seems level, no road surface is truly smooth, which is why shocks and struts are important for maintaining control and a smooth ride. While the terms “shocks” and “struts” are often used interchangeably, they are separate components ...
How long do you need to have shocks and struts inspected?
It is recommended that you have your shocks and struts inspected after 50,000 miles or according to your vehicle manufacturer's maintenance schedule.
Why is it important to replace struts?
Replacing old or worn out shocks and struts isn't just beneficial for your vehicle, it can also protect your investment in your tires by reducing unnecessary wear so you can get more life from them.
What is a strut in a car?
Struts are structural components of certain vehicles’ steering and suspension systems. They usually consist of a spring and a shock absorber. 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.
How long does it take for a Geico shock to be inspected?
It's best to have your shocks and struts inspected after 50,000 miles or according to your vehicle's maintenance schedule.
Where are shocks mounted?
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. It's important to check both front and rear wheels as you might have both shocks and struts.
