10 Best Shock Absorbers – Reviews & Buying Guide

Best Shock Absorbers

Your vehicle will undergo all kinds of shaking and bouncing when on the road, but with the best shock absorbers, you will hardly notice any of it.

Shock absorbers are meant to absorb shock or dampen the ride to make it smoother. They work by dampening the shaking and bounce that come from the spring and tires and by ensuring the chassis does not move according to these actions.

Like with most other vehicles parts, they get worn out at some points or even get damaged as a result of things like broken seals or leaking oil, and so you will need to change them.

When replacing your shock absorbers, you need to find something that suits the vehicle type and model and improves the ride quality. Here we review 10 top rated shock absorbers and also provide a handy buying guide.

Types of Shock Absorbers

As you shop for a good shock absorber for your vehicle, one of the first things you need to understand is that they come in two configurations which are twin tube and mono-tube.

Each of the two designs or configurations is ideal for a particular driving style and desired ride quality. Hence it is important to understand what each has to offer to determine what is the most appropriate for your car or truck.

#1. Twin Tube

Generally, the twin tube shock absorbers will consist of the inner working tube and an external tube that acts as a hydraulic fluid reservoir and this explains its name.

These shock absorbers are also available in three types which are gas charged, position sensitive damping and acceleration sensitive damping.

Gas Charged

gas charged shock absorbers

The main role of the gas charged shock absorbers is to prevent the hydraulic fluid from being aerated. It makes use of pressure from nitrogen gas to compress air bubbles in the hydraulic fluid. By doing this it prevents the mixing of air and oil which creates foam.

Because foam can be compressed it can affect the performance of the shock absorber, unlike fluid which cannot be compressed. With the reduction in aeration, the shock absorber is able to react more predictably and relatively faster for quicker response time.


  • Reduced aeration
  • Improved handling
  • Quicker response time
  • Reduced fade

Position Sensitive Damping (PSD)

PSD shock absorbers

PSD shock absorbers are designed to strike a perfect balance between handling capabilities and ride comfort.

These shock absorbers use an advanced technology that goes beyond controlling the velocity of the hydraulic fluid by also taking into account the position of the valve on the pressure tube.

The key to the functioning of this mechanism is having a pressure tube with precision tapered grooves.

Great attention is paid to every detail from the length of the grooves to their depth and taper to ensure the shock absorber will provide an optimal balance between ride comfort and control.

With the PSD shock absorbers, you essentially have a pressure tube with two zones. The first zone acts as the comfort zone which is where the normal driving will take place while the second zone is the control zone for demanding driving conditions.


  • Rapid adjustment to changing road conditions
  • Two shocks in one
  • Provides both control and balance.

Acceleration Sensitive Damping (ASD)

ASD shock absorbers

Like the PSD shock absorbers, the acceleration sensitive damping ones are also designed to provide a good balance between control and comfort.

With these shock absorbers, you will get greater control and improved ride comfort. They achieve this by going beyond the velocity sensitive damping and instead focusing on impact.

The increased focus on the impact on the ASD shock absorbers is achieved through a new compression valve design.


  • Enhanced control and comfort
  • Reduced ride harshness
  • Automatic adjustment to road condition changes

#2. Mono-Tube

Mono-tube shock absorbers

Mono-tube shock absorbers are high-pressure gas shocks that only have one tube which is the pressure tube. Inside the pressure tube, there are a couple of pistons which are the working and dividing pistons.

The key difference between the twin tube and mono-tube shocks is that the latter will allow for upside down or right side up mounting as it will still work either way.

Also, the mono-tube will not have a base valve as all the control during the extensions and compressions will occur on the piston.

For these shock absorbers, the rod and piston have to move up and down to balance the force during operation.


  • Allows for upside down mounting
  • Working tube is exposed to air for cooler running

Buying Advice: If you want a shock absorber that will help give your vehicle a ride that is as close to factory characteristics as possible, go for the twin tube types. But, if you want to increase the vehicle's responsiveness go for the mono-tube types. Mono-tube shock absorbers are also the best for replacing factory-installed mono-tube shocks.

Best Shock Absorbers Buying Guide

How to Buy the Best Shock Absorbers

One cannot overemphasize the importance of always ensuring that you are a getting the correct shocks for your car or truck.

And this is because the wrong shock absorbers will not only affect the ride quality but also the vehicle safety. But, you should not have any issues with shock absorbers if you consider the following factors when buying them.

#1. Style

Shocks will come in different styles and each will have merits and demerits and will be suitable for different riding conditions. Here are some of the most common shock absorber styles out there.

Gas Shocks

Many manufacturers will provide gas shocks as original equipment quality shocks.They have oil and nitrogen gas sealed inside which are what cushions your ride. Because they can handle the extra bouncing better, they often last longer on the small vehicles than the standard shocks.

Standard Shocks

Standard shocks are generally what many car manufacturers will have on the car when you get it. These shocks will not have any special or unique features as they are just basic, and you will hardly get any that can serve you for more than 100,000 miles.

Heavy-Duty Shocks

Because the heavy-duty shocks are mostly made for use on SUVs, trucks, vans and other relatively larger vehicles, they will come with a larger center shaft and better attachment points than the gas and standard shocks.

With these types of shocks, you will get a stiffer ride until the vehicle gets a heavier load which is when they even out for a smoother ride.

Automatic Level-Control Shocks

These are the kinds of shocks that you would typically find on the expensive luxury vehicles. They use an air pump system that will only be activated when there are differences in the vehicle’s weight distribution.

When you have passengers on your luxury vehicle or extra weight, the air pump is activated to add pressure to shocks to compensate for the extra weight so that the ride remains smooth.

Air Shocks

Air shocks are similar to the automatic level-control shocks in that they require air to be added to the shocks, but their work mechanism is more of a manual process.

These types of shock have an air inlet that will allow air to come in and pressurize the shock to lift the vehicle for better control and improved ride quality.

Overload Shocks

Overload or coil-over shocks as they are also referred to as will have a spring coil around the outside section of the shock cylinder. This coil is meant to help vehicles stiffen the shock’s reflex action and they are great for use on off-road vehicles like rock climbers.

#2. Compatibility with Vehicle

The many types of shock absorbers out there can make it hard to choose the right one for your vehicle. But, the most important thing to always consider is the vehicle compatibility. Here is a simple compatibility summary to help make things easier for you.

Vehicle Type

Shock Absorber Type

Off-Road T​​​​ruck

External Reservoir Shock Absorber

Off-Road Truck (raised)

Monotube Gas Shock

Van (full-size)

Monotube Shock

Pickup (standard)

Original Equipment Replacement Shock

SUV (heavy-duty)

Air Springs and Monotube Gas Shocks

SUV (standard)

Twin Tube Shock

#3. Price

While the quality of the absorbers, their performance and compatibility are the most important factors to consider, the price also matters a lot and you cannot overlook it when picking shocks.

Always start by coming up with a budget or decide on how much you are willing to spend on the shocks and look for the best-performing ones within your budget.

The size of your vehicle also determines how much you will spend because small saloon cars use cheaper shocks than SUVs and heavy-duty trucks.

#4. Driving Conditions

The roads that you drive through often also determine the best shock absorbers for you. For example, off-road adventures will require tougher shocks that can withstand more bounce.

If you ride in smooth roads often, almost any shock absorber can work for you as it will not have to face a lot of bounce or abuse.

The standard and gas shocks that come with most cars are often good enough for normal driving conditions while the heavy-duty shocks are the best for muddy roads and rough roads full of gravel.

#5. Material and Durability

Even if your shocks offer the best rides and control, they will not be very convenient if you have to change them after every few thousand miles. This also means you have to spend more on the shock absorbers which can be expensive in the long run.

Before you buy, shock absorbers you should check the material and ensure you only settle for something highly durable.

Shocks can be made from various materials, but the most common ones are steel and aluminum. Steel shock absorbers are often the cheapest, but they can be a little cumbersome to install.

Aluminum shocks, on the other hand, are adjustable and lighter which is why many drivers will prefer them, but most are relatively pricier than the steel types.

Besides the material, also check on the overall construction of the shocks and make sure that it is sturdy enough for maximum durability.

#6. Ease of Installation

If you are one of those vehicle owners that always prefer to do everything on their own without paying a mechanic, the ease of installation of shock absorbers is a vital factor to consider.

It is important to note that some shocks will require customization or modifications for installation. For such types of shocks, you will often need to pay a professional for installation.

If you still want to install the shocks that require modifications on your own or have the mechanical skills to do it, make sure that the shocks come with a mounting kit and detailed instructions.

For the shock absorbers that do not require modification, installation should be straightforward, and you can easily do it yourself by following the instructions that most manufacturers will provide.


It is possible to drive a car with worn shocks and some people still do it for many miles, but it is not something you should look forward to or even get used to.

Shocks are integral for getting a smooth ride, good vehicle control and also for other things like braking and turning, and hence you need to replace them when they get damaged.

Finding best replacement shock absorbers should now not be a problem as this piece highlights everything you need to know from the types to the important things to consider when shopping.

And with our top 10 heavy duty shock absorbers reviews above, you should also now an idea on some of the best brands and models to buy.
