Air suspension is the vehicle suspension powered by an electric or engine-driven air pump or compressor. The compressor pumps the air into bellows, which is made from rubber. The air pressure then inflated the bellows and it’s used in place of conventional steel springs in cars and heavy-duty vehicles. This includes loading trucks and even buses.
Most of the time, air suspension kits are used on semi trailers and passenger trains. However, they may be used on cars as well.

How Do Air Suspension Kits Work?
Air suspension is the vehicle suspension powered by an electric or engine-driven air pump or compressor. The compressor pumps the air into bellows, which is made from rubber. The air pressure then inflated the bellows and it’s used in place of conventional steel springs in cars and heavy-duty vehicles. This includes loading trucks and even buses. Most of the time, air suspension kits are used on semi trailers and passenger trains.
An air suspension kit is a specialized set of automotive components that allow an individual to adjust their vehicle's height to meet precise specifications. When properly installed on all four corners of a vehicle, an air suspension kit is often able to improve operational performance. This is particularly true when it comes to handling on uneven surfaces because the airbag system in the air suspension kit is ready to smooth out harsh shocks.
Types of Air Suspension Systems
Benefits of Installing Air Suspension
One of the obvious benefits of installing an air suspension system is a smoother ride overall, regardless of your vehicle’s size. For mid-sized vehicles, an air suspension system can mimic the handling of a luxury vehicle, especially when traversing urban streets. Meanwhile, large trucks can enhance their towing capabilities after an air suspension system has been properly installed.
How To choose a Quality Air Suspension Kit
The whole idea of air suspension is to provide constant ride quality: no bumps, no shaking and no trailer sway. In the last ten years, air suspension has become extremely popular in vehicle culture. They are used to provide adjustable suspension, allowing cars and other vehicles to sit lower than average while still managing to clear obstacles. The popularity of airbag suspension has created a massive awareness about the benefits of installing them on cars and trucks.
There is a massive improvement in overall road handling with an air suspension kit, and depending on the type of system that is installed, a custom airbag suspension has the power to inflate and deflate automatically. There are some things that you should consider before you buy an air suspension kit for your vehicle, though, and we’ve listed some of them below.
There are several different types of air suspension systems, each of which come with their own functional benefits and drawbacks. Most of these types are made from heavy-duty rubber, allowing them to remain resilient in the face of repeated carloads of strain. More information on these different types can be found in the “Types of Air Suspension Systems” section above.
Modifications to your vehicle will affect appearance and performance, so you need to ensure you know what you need when you buy an air suspension kit before you do so. There are kits for off-roaders, and are more expensive and then there are others out there that are for normal street use.
Quality of Parts
When it comes to modifying a critical vehicular system such as the suspension, you should only select quality parts from reliable manufacturers. While some major brands such as Firestone make air suspension systems, some lesser-known brands also make quality kits as well. User reviews are a great way to gauge the overall quality of this domain.
Compatibility & Size
Each air suspension component takes up a bit of physical space inside of your vehicle. As such, different size kits have been created to accommodate mid-sized to over-sized vehicles. Choosing an incompatible size can be a serious issue that leads to the part’s failure. Accordingly, you should always consult a mechanic before selecting a specifically-sized kit.
Ease of Installation
Air suspension kits are complex, so you should always leave the kit to be installed by a professional mechanic. You can use DIY kits, but you need to be confident about installing such a kit before you go ahead. The integrity and safety of your vehicle is at stake here, so it’s not something to mess with. If it isn’t installed correctly, you could void the warranty that you were given: lifetime or not.
Air suspension kits are different from hydro suspension systems – hydraulics – and the two shouldn’t be confused. Air suspension is a good investment for anyone who wants a car that can perform better every single use.
You don’t have to spend the earth on a proper air suspension kit to have the best in the industry. You need to take into consideration the fact that your stock suspension components would be replaced by this system. There are a lot of kits in the online market that can cater to any basic or automatic need, all it takes is the right research.
Some air suspension kits come with a warranty, which allows the users to recoup the cost of the part if it fails unexpectedly or fails to meet expectations for performance. When comparing prospective kits, be sure to factor in the value of a warranty because such an investment may save you money on replacement parts down the line.

When to Replace Your Air Suspension
Several specific symptoms will signal that it is time to replace your vehicle's air suspension system. First, if you notice an excessive amount of wear or abrasion on the rubber sleeve's surface, it will likely wear through soon thereafter. Also, if your system's airbags are failing to hold pressurized air efficiently, a new set of airbags or an entirely new system may be in order.
What’s Included in an Air Spring Kit?
Most standard air spring or air suspension kits include the following:
Coil Spring vs Air Spring Suspension
Coil springs and air spring suspension systems are often compared to one another due to their shared use of an air-filled bladder to supplement a vehicle’s suspension capabilities. However, they differ noticeably when they are put into action.
For example, coil springs are known for their ability to provide larger vehicles with more towing power. They accomplish this by filling the gaps in the built-in suspension springs as they compress, which in turn gives the suspension system more torque.
Meanwhile, air suspension systems are prized for their ability to emulate the supple movements of luxury vehicles. Also, air suspension systems are far more tuneable, allowing users to more efficiently customize their vehicles ride-height and stance over time.
Air Suspension vs Traditional Suspension
Traditional vehicular suspension systems use a series of heavy-duty springs and struts that actively prevent the entire vehicle from jolting about when traveling over uneven surfaces. Instead, these springs compress and decompress to allow for more balanced handling.
Air suspension systems go above and beyond these standard capabilities because they are often more able to respond to added weight and pressure at the vehicle's four corners. This, in turn, prevents a great deal of bouncing as a car moves along, thus matching the handling of a luxury-grade vehicle or a heavy-duty truck.
Installation & Maintenance Guidelines
Installing an air suspension system is considered a more professional-grade vehicle modification. That being said, you can certainly learn how to perform this task by carefully studying how-to guides on the topic as well as consulting with a trusted auto mechanic. Also, this following video will provide you with a step-by-step guide to installing your newly-purchased air suspension kit:
Generally speaking, maintenance guidelines for your specific style of air suspension system will be explained in your owner's manual. That being said, there are several general maintenance tips that all air suspension system users should keep in mind.
First and foremost, you should inspect your air suspension system at least once a year. At that time, you should check for aging across the rubber surface of your airbags. At the same time, you should ensure that there are not any repetitive wear spots that may give way and allow moisture into the airbag before your next inspection.

People Also Ask (FAQs)
How often should you replace shocks and struts?
Generally speaking, shocks and struts should be replaced every 50,000 to 100,000 miles. However, if your vehicle regularly operates in high-impact areas, then you may consider having your shocks and struts checked by a certified mechanic on a more regular basis (such as once a year).
How long does it take to replace suspension?
A vehicle's suspension system is complex, with each component requiring several hours to replace properly. Each shock, for example, typically requires 2-3 hours to safely and securely remove and replace. As such, a full suspension replacement may take up to 5 days, depending on the condition of the replaced parts.
How long do air suspensions last?
Most standard air suspension systems last between 50,000 and 75,000 miles. However, some manufacturers list their systems as lasting up to 10 years of regular use. In either case, you should regularly inspect your air suspension system and make a replacement when an excess of wear begins to appear throughout the system.
How much does it cost to have a professional mechanic install air suspension on my vehicle?
In consideration of both parts and labor, current estimates place a professional installation of an air suspension system at between $2,480 and $2,520. Specific prices will vary from mechanic to mechanic, though.
How can I make my air suspension more comfortable?
Your best bet for getting a more comfortable ride out of your air suspension system is to experiment a bit. Though the manufacturer's inflation recommendations will likely provide the most balanced performance, you may find that a slightly over or under-inflated airbag better suits your vehicle's suspension needs.
What are the best air suspension kit brands?
There are several popular manufacturers in the air suspension kit business today, including Firestone, Air Lift, and Unity. Each brand’s products can be purchased online at a noticeable discount from retail prices.
As you can see, there's a lot to know about air suspension systems before you go about installing one of your own. Though these innovative systems can truly enhance your vehicle's stability and control in a variety of situations, they also require some amount of practice to install correctly. If you're still set on installing one of these systems, be sure to use the Air Lift 57275. Its use of a double-chambered construction and nylon lines make it durable beyond all expectations.
