This is by far our favorite model when it comes to durability. This model is equipped with a self-lubricating seal, which helps retain both gas and oil for more efficient compression.

What’s more, this model is pretty customizable compared to the competition. For example, it has a knob, which allows you to adjust the damping control and the friction for driving on rough roads.

The number one reason buyers get this one over any other option available is that this model does a pretty good job of helping truck owners with their stock height truck.

It helps balance out the height, and the end result looks pretty good. Furthermore, we’re pretty happy with how it handles bumps or any other irregular road. When going over bumps, it’ll go back to its proper position in a smooth and controlled manner.

These heavy-duty designs are made to replace the stock ones. In fact, one could say they’re better than any other stock shocks. Considering that they’re nowhere as expensive as the factory ones, we’d say it is a steal.

Another point buyers have stretched out is that their trucks feel way more stable than before. This is thanks to its monotube gas pressure system.

As far as the installation process goes, you’d need at most 2 hours to get through the entire process. Not much different than other shocks available.

What We Liked

  • Provides excellent stability

In addition to that, the feedback regarding the installation process is mind-blowing. At most, you should expect to get it done within 4 hours. And, this brand includes a PDF file showing the assembly process.

This is a significant advantage as most competitors can’t get their shocks to remain silent. Better yet, this model is your best bet if you need to tow trailers. It is designed to help truck drivers to maintain ride height when dealing with over 1,000 pounds.

“But as good as those features are, there’s just something that we can’t wrap our heads around. You need to get rid of your 4-inch leveling kit. Meaning if you a 2-inch leveling kit plus 2-inch lift locks, you’ll have to remove them.”

What’s more, you can even tow boats and trailers, making it one of our favorites shocks for carrying heavy loads. While some models struggle to provide enough ground clearance, these shocks have a much easier time preventing bottoming out.

Once you’ve installed these shocks, you’ll notice the massive improvement on your leveled truck. Better yet, we’re pretty satisfied with how well it handles ride height. Even when the vehicle is under heavy load, the truck will maintain its height.

For instance, the shocks are designed to withstand over 1,100 pounds. The shocks are pretty customizable. You can adjust them to handle different weights. For example, if you’re towing a boat, you can set them up so that they can withstand the extra weight.

For what it’s worth, installing these shocks does not take much time. The company provides everything for the assembly process, so you won’t find yourself going to a hardware store.

A lot of people seem to be skeptical about aftermarket shocks. However, with companies like Monroe getting better each passing day, you can sleep well at night knowing they got your back.

What’s more, these are gas shocks. These shocks are designed with nitrogen, making them one of the most durable shocks available. Consumers have also expressed how quiet these shocks are. Even when going over bumps, you won’t hear any knocking noise coming from underneath the vehicle.

Another feature everybody seems to be happy about is that many buyers have noticed a massive improvement when towing trailers. For instance, if your truck bounces when towing another vehicle, the bouncing should stop after installing them.

What We Liked

  • Perfect for towing
  • Good-looking design
  • Reduces bouncing
  • Easy to install

What We Didn’t Like

Buying Consideration

Below, we’ve narrowed down all the features your future shocks should have. That said, consider the following features:

Heavy-duty Shocks

One of the best shocks is heavy-duty shocks. These are ideal for large trucks. Moreover, going off-road with one of these is a walk in the park. They are super durable and prevent bouncing.

Gas Shocks

Gas shocks are also quite popular among truck owners. These shocks are super-efficient when it comes to handling bumps. What’s more, newer vehicles are equipped with gas shocks.


Ever noticed how friction ruins your driving experience? It’s annoying having to put up with it as it continually slows down the car. To eliminate this issue, make sure the shocks come with special modifiers that can decrease friction.

This way, you’ll have more control over your vehicle when driving over bumps. And, this is an excellent way to increase performance.

Rebound Dampers

Rebound camping controls how fast or slows the shocks should return to their normal heights after going over bumps. This allows the shocks to be ready the next time they need to absorb the next impact.

This is achieved as the springs store compression when the vehicle goes over bumps. That said, make sure your shocks increase damping for a more enjoyable riding quality.


Another feature you should look into when getting one of these shocks is that they should make little to no noise when driving. This might not be a deal-breaker for most drivers, but if you hate hearing noise from underneath the vehicle, you’ll appreciate that feature.

Noise is not something that will impact performance. Worst-case scenario, they could make the ride stiffer. But it can certainly be annoying after a while. Therefore, make sure your shocks make little to no noise.


If anything, drivers know how annoying it is to find out their shocks got corroded. When this happens, you’ll notice how poorly your vehicle performs. What’s more, they could fail when driving.

To get around that, make sure your shocks are corrosion-resistant. This added feature alone will make your driving experience way better. And you won’t have to worry about the shocks getting corroded over time.


Similar to the previous one, make sure your shocks are scratch-resistant. They are exposed to several elements, so getting a couple of scratches is not out of the question.

When this happens, they begin to lose their original appearance, which can be rather annoying.

Leveled Truck

If you have a leveling kit installed, you want to be careful when adding new shocks to your leveled truck. Adding new shocks could ruin the CV joints. What’s more, if you have a 4-inch leveling kit, they might not be compatible. They’ll make a lot of noise, and you’ll soon need to replace them. So, watch out for that.

Factory Rake

Most shock extenders should lift your vehicle just a little bit. But that slight boost should be more than enough to get rid of that ugly factory rake.

So, when getting one of these shocks, make sure it lifts your vehicle just enough to balance out the truck. It’ll look way better this way, and that slight balance will not bother you anymore.

Zinc-coated Stainless Steel

Coating metal drastically increases the lifespan of any metal being covered by it. Zinc coating is a great way to stop moisture from penetrating socks. This way, you’ll heavily mitigate any future corrosion.

Monotube Shocks

When shopping around for new shocks, you’ll come across the term “monotube shocks.” Simply put, these shocks have a much easier time improving damping precision than other shocks out there.

On top of that, they’re also pretty reliable when it comes to decreasing heat. Overall, the monotube shock is the go-to option for many truck drivers, given how reliable they are in the long run.


Is there anything we didn’t go through when covering all the shocks? Well, here are some commonly asked questions about them, which you might find interesting:

How can I smooth out my Chevy 2500HD?

The best way to ensure that your Chevy 2500HD performs incredibly is by adding new shocks. Aftermarket shocks are meant to increase your vehicle’s performance. For example, when going over bumps, aftermarket shocks should decrease bouncing.

What Shocks improve your truck’s ride?

The monotube shocks are among the most reliable models you can get right now. They are super-efficient and will dramatically improve your truck’s performance. Moreover, they hold up pretty well over time.

Just how much can aftermarket shocks improve my ride?

Ever noticed how your vehicle bounces up and down after driving over bumps? Well, you can get mitigate that annoying bouncing by installing aftermarket shocks. In addition to that, if you need to tow a trailer, new shocks would allow you to handle the extra weight.

How many miles can shocks last?

This heavily depends on the brand. But in general, you should expect your new shocks to last anywhere from 50,000 up to 100,000 miles.

Do I need to get an alignment after getting new shocks?

Yes, professionals suggest getting an alignment done after replacing a vital suspension component. Anything that changes your vehicle’s geometry should get an alignment. This also holds true if you installed a leveling kit.

Bilstein vs KYB which one is better?

Bilstein is by far the better choice here. Both brands are pretty good and have been around forever. However, Bilstein is the number one option for many truck drivers worldwide. That is not to say the KYB is not a great company. It’s just that drivers are more familiar with Bilstein.

KYB VS Monroe which brand has the best shocks?

Both companies make top-notch shocks. However, many drivers will choose KYB over Monroe. Perhaps the most significant advantage Monroe has over KYB is that they sell cheaper shocks. But KYB is more reliable. Also, if the price is close, you’re better off getting KYB.

Do I need longer shocks on a leveling kit?

If your leveling kit raises your vehicles higher than 3 inches, you’ll need to get bigger shock absorbers to make up for that distance. If you don’t get longer shocks, you could damage the CV joints. And, you could hear a constant knocking sound.

Should I get shocks or struts?

Damaged shocks and struts can affect braking distance, performance, and even stability. Ever seen one of those vehicles that almost looks like the tires are flopping up and down? Well, the shocks are probably damaged. In other words, both are essential parts.

Why are Shocks made by Bilstein so expensive?

Bilstein is your best bet when it comes to shocks. They are relatively more expensive than their competitors since they charge a premium for their performance. But no other brand will offer you that peace of mind Bilstein offers.

Nonetheless, they have plenty of different models available, so it’s just a matter of shopping around until you find one suitable for your budget.

Are aftermarket shocks better than factory shocks?

Most aftermarket shocks are better than the factory ones. Keep in mind that these aftermarket shocks are designed to improve your vehicle’s performance. Handling, riding quality, and damping are the main reasons why truck owners replace their stock shocks.


We’ve carefully chosen the best shocks for 2500HD Duramax. Any of the above shocks were selected based on the user’s experience. As for the brands, we went with the most well-known brands in the automotive industry.
