Although cars and trucks have indeed made great progress in design and engineering, shock absorbers have really not changed much over the years. Many production cars still rely on them, and they are still an important part of the vehicle's driving quality and performance. However, they sometimes fail. Whether this means they are not functioning properly or performing as needed depends on your situation. As with any malfunctioning component, you will eventually need to be replaced, and we are here to help you track them down. We will show you some of our preferred products and provide you with a buying guide. Regardless of the specific application, these options should be used as an indication of what to consider.
Monroe is an industry leader for a reason. Reflex's high quality, improved performance and competitive price are just an example.
These ACDelco shock absorbers are direct replacements for popular General Motors trucks and SUVs. They will restore the ride quality of the factory at an affordable price.
The Bilstein 5100 impact is a big improvement in almost every aspect. The first-class quality and the balance of performance and ride quality make them the dream of many car owners.
Our reviews are driven by hands-on testing by actual buyers, expert opinions, "popular wisdom" evaluations, and our own expertise. We always strive to provide true and accurate guides to help you find the best choice.

Monroe's reliability, quality, and affordable price are sufficient for most people, so this is an upgrade that can hardly be ignored. Monroe has long been a leader in the industry and a supplier of original parts to many manufacturers. Reflex is a single-tube inflatable shock absorber that balances performance and comfort. The overall design makes it stable and consistent. This shock is also at a competitive price point, which helps it fall within the budget of many car owners.
Although this shock is a direct substitute for many trucks and SUVs, it does have some problems. One of the most common problems is that the ride height is low when installed, and lighter apps will notice that the shock absorber makes the ride harder, which may be undesirable. Quality control also seems to be an issue, but Monroe supports the product.
ACDelco is a trusted premium brand of General Motors, and its affordable price makes it a must-have for proper applications. If you own a General Motors, you may be familiar with ACDelco. Its reputation as a supplier of quality original parts makes it the brand you look for when performing general maintenance. This shock absorber is directly matched with the original equipment and is designed to restore the ride quality and performance of the factory. It will also withstand everything you did during the initial shock.
However, there are also some problems. The application guide attached to this particular shock absorber is misleading for some vehicles. Missing parts such as hardware and bushings are also common, so you may need to reuse old hardware.
These shocks cover the basis of many car owners who need suspension updates. Although these special shock absorbers are designed for F series trucks, Bilstein is one of our favorite manufacturers. The 5100 series shock absorbers are an improvement for many car owners because these shock absorbers provide improvements in performance, comfort, and almost any other shock absorber you want. These are some of the best shocks on the market, which is why you will find this name in many corners of the industry.
This particular option replaces all four shocks. But it is undeniable that the price of quality is high. In addition, the impact can significantly change the ride characteristics, which is worth reading before buying. In addition, quality control issues may arise.
Fox Performance is an off-road route that cannot be ignored. Quality and performance distinguish it from the competition. When you take an SUV or truck off the beaten track, the original shock absorber is not the best choice. Fox is the manufacturer of some of the best off-road shock absorbers due to its outstanding performance and the high-quality parts used. This special kit covers JK Wranglers, all four corners have 1.5-3.5 inches of lift. These improvements make it a reliable choice, especially considering their ability to handle on- and off-road conditions.
However, the price may discourage many off-road vehicles. We also did not put it higher on our list because it is suitable for limited vehicles. Most importantly, these are major changes in the ride quality of the factory, which may not be ideal in some cases.
KYB shock absorbers are popular in older vehicles because they provide significant performance improvements at a competitive price point. If you are developing a classic car, it is worthwhile to switch to KYB rear shocks, and this special setup directly matches many popular classic GM models. They are much harder than the ones that come with most cars, can help the vehicle stick to the road when launching and cornering, and even help correct posture.
In addition to everything these shocks bring, they are more affordable than many classic performance shocks, and even the same as many original equipment shocks.
There are many great shock absorber brands on the market, but when we need to choose the best, we will definitely try and stick to the ones that we know are effective or the most popular ones for most people. We have experience with every brand we recommend. In addition to ride quality and reliability, we also make sure to consider some custom applications to make a list that we believe covers the broadest market.
Our product selection, ranking and awards for this story are based on research. Although we have not actually tested all these products, we have reviewed consumer recommendations and data, tutorials, and general discussions on social media and forums. We also consider prices and specifications in the context of market segments. And, of course, we rely on our institutional knowledge of the automotive sector to weed out weak products.
Not all shock absorbers are the same, not all applications need the same characteristics, and not all car owners want the same things. This buying guide is designed to help you understand the basics of shock absorbers so that you can start looking for the perfect set.
There are three basic types of shock absorbers on the market. These can be divided into their own sub-categories to really help you hone the characteristics you need. Nevertheless, you still need to understand the general differences to make sure you are in the right field.
Traditional shock absorbers are the most basic products. They are just telescopic bodies with valves and hydraulic oil to control damping. You will find these on all four corners of old vehicles, but they are usually kept in the rear of modern cars.
These shocks are usually the most affordable, but that doesn't mean they are all basic. They can be configured with a single tube or a double tube, inflatable, external air storage tanks, and even adjustable damping, so as to make some huge improvements in control and ride quality.
Most modern cars use so-called pillars at the front end. On older vehicles, the shock absorber is simpler because the spring and shock absorber supporting the vehicle are two separate parts. The pillar basically combines the two together, thus making significant progress in overall control.
You can see the difference between a shock absorber and a strut, because the strut has a coil spring wrapped around the shock absorber. Although shock absorbers are usually regarded as the next step, you can still find pillars with the same aftermarket upgrades as traditional shock absorbers. It is important to remember that shock absorbers and coil springs can usually be replaced independently of each other.
Coilovers and struts have a lot in common, and they are usually regarded as an upgrade. We say this because the shock absorber is designed to give you full control of the spring and shock absorber inside.
To keep it short, you can adjust the ride height and damping capacity of the components to almost unlimited configurations. This is great for performance applications. Because it is usually not something you need on a street car, we chose to save any suspension recommendations for another day.
In fact, the choice of shock absorber is largely influenced by application requirements. These are application-specific parts, so unless you go all out for a custom build, you will need to replace the shock absorber with the same type of shock absorber used in the factory. Fortunately, searching by year/manufacturer/model becomes simple. In most cases, the characteristics of the shock absorber are what you really need to pay attention to.
The shock absorber is filled with hydraulic oil. This is used with internal valves to slow down the movement of the shock absorber. Both determine the ride quality together. With the impact cycle, the fluid heats up, aeration occurs, and performance decreases. One way to reduce the problem is to charge the shock with nitrogen.
Inflatable shock absorbers are inherently more stable, but they are usually associated with high-performance vehicles because they make the driving stronger, while the relaxed hydraulic system is more of a luxury. The fact is that most vehicles today benefit from inflatable shocks because they can withstand reduced ride quality.
You will find that the shock absorbers declare that they are dual-tube or single-tube designs. What does it mean? The way the shock absorber works is that you have a pipe filled with hydraulic oil, a piston controls the movement of the internal valve, and the internal valve slides up and down in the pipe. The single tube shock absorber is characterized by a wider piston in the larger tube, while the double tube has a smaller piston in the smaller tube, surrounded by an auxiliary tube filled with hydraulic oil.
The advantage of the dual-tube design is that it is a low-pressure system, so it can create a softer ride experience. The larger piston in the single tube hardens the object, thereby improving performance. What suits your vehicle depends on the requirements of the factory, but single-tube shock absorbers are usually better.
As we said before, the piston inside the shock absorber has a valve. The direction of the valve determines how easy it is for the piston to pass hydraulic fluid in either direction, which does affect the overall performance and ride quality. In most cases, this is not something that most car owners need to worry about.
The manufacturer came up with a combination that suits their driving style, with keywords such as comfort and performance as much as you need to know. However, the shock with adjustable valves does exist. They are a good choice for those who really want to adjust the vehicle suspension. However, you should be careful before buying, as you will need to spend a lot of time making adjustments to make them suitable for your application.
If it looks too good to be true, it usually is. If the price of a shock absorber is ridiculously low, but has adjustable valves and uses all the gorgeous keywords, then it should send some red flags. It may reduce the overall design, but they will definitely disappoint you in a short time. Take the time to read whatever you are about to buy to make sure that the shock absorbers don’t leak or break suddenly, and that they really fit.
If you can determine the year/make/model search and understand the basics of shock absorbers, then you are ready to determine the perfect shock absorber for your car. Before you start, we have some tips to share with you.
A correct set of shock absorbers can have a major impact on overall ride quality. Keywords will let you find the right place, but each manufacturer uses its own formula, which means you may not know what will happen. A good way to get the information you need is through online forums. Find a forum suitable for your brand and model, and see what other people think of the impact of their vehicle, to help you better understand what to equip.
When you start to change the vehicle, different requirements will be imposed on the shock absorber. For example, tightening the steering requires something more sensitive, and changing the ride height will change how much travel is required. When you start making these changes, keep the shock absorber in mind to make sure you choose the perfect match.
The spring and shock absorber go hand in hand. The spring supports the vehicle and keeps the body elevated, while the shock absorber reduces the spring rate. If you want to completely change the characteristics of the suspension, you may need to solve these two problems at the same time to achieve the ultimate goal.
We may not know what is beating in your skull, but we can try to solve this problem by answering some of the most common questions about shock absorbers.
Poor traction, excessive bounce, vibration, dullness, oil leakage and poor ride quality are all symptoms of poor shock absorbers. If you are not sure which is the bad one, you can try to compress the suspension of the vehicle at all four corners and pay attention to the inconsistencies.
You can drive a vehicle with bad shock absorbers, but this is not safe. A malfunctioning shock absorber compromises performance and safety, and puts pressure on other important components. Make sure your vehicle has good shock absorption at all four corners to prevent any problems.
Under normal conditions, the shock absorber should last approximately 40,000-50,000 miles. However, they can only endure so much abuse. If you take your vehicles off the road, quickly turn corners, or often drive on bumpy roads, you can expect to replace them sooner.
The front and rear shock absorbers are different. They may provide the same performance characteristics, but are usually different from each other. The length of the shock absorber and the installation method vary, and most modern vehicles are equipped with strut shock absorbers at the front end.
We can safely say that Monroe Shocks & Struts Reflex shock absorbers are a good choice for most applications. However, something like the ACDelco Professional Premium inflatable front shock absorber is great on a budget.
However, all of this can be explained. The shock absorber you use depends on your personal taste, driving style and application.
