What is the function of shock absorber?
The role of the shock absorber is to keep the car’s tyres in permanent contact with the road, helping to provide optimum grip, when cornering and braking. Shock absorbers are part of the suspension, so if the shocks are worn, the vehicle’s ride and comfort is compromised.
How does a car shock absorber work?
The shock absorbers dampen the movement of the springs by converting the spring’s kinetic energy into thermal (heat) energy. Shock absorbers are an oil-filled cylinder. When your vehicle’s suspension moves, a piston moves up and down through the oil-filled cylinder.
Why shock absorbers are used in vehicles?
In a vehicle, shock absorbers reduce the effect of traveling over rough ground, leading to improved ride quality and vehicle handling. While shock absorbers serve the purpose of limiting excessive suspension movement, their intended sole purpose is to damp spring oscillations.
Which is better gas or fluid type shock absorber?
Nitrogen gas is a cold gas, this means that besides not being flammable, keeps the shock absorber cooler than an oil shock absorber, been colder it will keep oil degradation by heat effect is reduced, making the shock absorber with gas a more durable shock absorber.
Which shocks give the smoothest ride?

What type of shocks are best?
There are two primary overarching categories of shocks: gas charged and hydraulic. Gas charged shocks are optimal for high speed driving, as there is no risk of aeration (air mixing with the fluid, causing foam and decreasing performance) like there is with hydraulic shocks.
Will replacing shocks improve ride quality?
Shocks and struts help keep the vehicle stable during acceleration and braking. The customer may think that new shocks and struts will simply make their ride smoother, but the truth is that new shocks and struts can do a whole lot more. New shocks and struts can make a vehicle corner and brake like when it was new.
Do you need an alignment after replacing shocks?
Should You Get an Alignment After Getting New Shocks and Struts? The short answer is—it depends on the type of suspension your car has. On some vehicles, the installation of new shocks and struts may affect your car’s wheel alignment. In general, you’re less likely to need an alignment after replacing shocks.
Should I replace all 4 shocks at the same time?
Finally, replace your struts and shocks in pairs Shocks and struts should always be replaced in pairs or, better yet, all four, for even, predictable handling and control. After all, all four have been on the vehicle for the same number of miles and worked under the same conditions.
How many miles do shocks last?
The general recommendation is that shocks and struts should be replaced every 50,000 to 100,000 miles. Here are some factors to help you determine if it’s time to replace your shocks and struts.
What are the signs of bad shocks?
The Warning Signs
- Instability at highway speeds.
- Vehicle “tips” to one side in turns.
- The front end dives more than expected during hard braking.
- Rear-end squat during acceleration.
- Tires bouncing excessively.
- Unusual tire wear.
- Leaking fluid on the exterior of shocks or struts.
Will bad shocks cause wheel hop?
Worn shocks cannot keep the tires firmly planted on the road surface. With worn shocks, the tires have a tendency to wheel-hop or skip, and at high speeds this causes chunks of tire to be torn from the tread.
How do I know when my shocks need to be replaced?
What Are the Signs that My Vehicle Needs New Shocks or Struts?
- Bumpy ride. 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.
How much does it cost to change shocks?
The cost to replace shocks is going to be slightly less than struts since they are generally not as complicated as struts. 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.
What’s the difference between shock and strut?
The major difference between shocks and struts is that a strut is a structural part of the vehicles suspension system where a shock is not. A strut is also a pivot point for the vehicles steering system and contains a coil spring. Because of this an alignment is always needed when replacing a strut.
What does it sound like when shocks go bad?
When going over various bumps, speed bumps, or potholes and your hear a knocking sound, it likely means you have worn shock absorbers. All it would take is for a crack to form in the rubber bushing and it will result in a tapping or knocking sound that you can hear each time you hit a bump while driving.
Should new shocks make noise?
There is most likely nothing wrong with the replacement units, but a metallic “clunking noise” typically indicates loose or worn mounting hardware. If the noise is present with a replacement shock absorber, check that the mountings are tightened securely, and look for other worn suspension parts.
Are struts in the front or rear?
Struts are typically installed in conjunction with the front wheels, but depending on a vehicle’s setup and driveline, they can also be mounted at the rear wheels. Just as there are different types of cars, there are different types of struts.
How long can I drive with bad struts?
As long as you like. BUT you will have to buy new tires, new STRUTS, possibly new springs, brakes repaired, etc…the longer you leave it. The things that the struts effect like tires etc,…will need to be replaced or repaired much sooner. So…you can ride on ‘worn out struts’ forever.
Are coilovers better than struts?
Summing up the advantages of coilovers over strut and springs are adjustable ride height and the higher spec units offering adjustable dampening and rebound and the ability to change springs to fine tune spring rates combined with lighter assemble reducing unsprung weight. Top end units will also be fully serviceable.
Are coilovers good for daily driving?
For a brief answer – no, coilovers are not really suitable for daily driving because they make your ride extremely stiff and uncomfortable. Although it’s possible to adjust coilovers to make it acceptable for daily driving.
Do coilovers make your ride smoother?
Absolutely not. Since most coilovers are also going to allow you to lower the ride height, the spring and shock rate should be increased to avoid the suspension crashing and bottoming out. Doing so will offer a performance bump to most any vehicle.
Do coilovers last longer than struts?
yes, coilovers should last as long as regular shocks.
How long do coilovers usually last?
about 150,000 miles
How often should you rebuild coilovers?
every 15,000
Can I put lowering springs on stock shocks?
Using just lowering springs is a bad idea. It will wear out the OEM shocks because the shocks will have to compress much more to absorb bumps. It’s logical; the spring is shorter and therefore the shock has to travel more when you hit [any] bump.
Do lowering springs ruin ride quality?
Your factory shocks’ overall ride quality is tuned to be most effective at the stock ride height. Lowering springs are shorter in length (most of the time) compared to factory springs, your shocks will be riding lower in their travel than they were designed to be at while sitting at normal ride height.
Do lowering springs ruin shocks?
Myth 1: If I buy lowering springs, I can’t use my original shocks. Fact: Springs that produce mild lowering of about an inch work well with newer factory shocks. In fact, Eibach’s Pro-Kit Spring Set and even their more aggressive Sportline Spring Set are designed around a vehicle’s original suspension.
