Air Suspension Parts | Air Compressors, Air Springs, and More
Good air suspension parts don’t have to cost a fortune. Strutmasters offers high-quality air compressors, air springs, and other air suspension components at an affordable price. These parts will allow you to repair your suspension system for a fraction of what you might pay at the dealership.
Compressors for air suspension systems
Your vehicle’s air suspension—as you might have guessed from the name—uses pressurized air to keep it at the proper ride height. That pressurized air is generated by an air compressor specific to that system.
These air compressors aren’t much different from ones you’d use in the shop or garage. Like those compressors, they use a vacuum to pull air in and direct it to the storage tank. This builds up pressure in the storage tank, which is then pushed out through air hoses as needed.
The big difference between your vehicle’s suspension air compressor and standalone air compressors is that the one in your car uses instructions from a computer to generate a specific amount of air. It then pushes that air out through the car’s air lines and into the air springs, inflating them as needed to maintain proper ride height.
When should you replace your vehicle’s air compressor?
Your vehicle’s air compressor is made up of moving parts. Like almost all moving parts, they have a limited working life. However, unlike some components, the lifetime of your air compressor is hard to predict.
Some of these compressors last the entire life of the vehicle. Others don’t make it to 100,000 miles. The truth is, your compressor can fail at any time.
Warning signs of a failing air compressor
These days, most vehicles have warning lights that will tell you when something in your suspension isn’t working. But often by that time, a component has failed and has already started to put extra strain on other parts of your air suspension.
Looking for early warning signs of air compressor failure can help you catch the problem before it does any further damage. Here are some things to look for:
Odd noises. In most modern systems, you’ll barely hear the compressor running, if at all. So if you start to hear sounds like clicking, whining, or grinding, your suspension air compressor could be starting to fail.
Abnormal cycles. Each car is different, but after a few thousand miles you should have a good idea of what your car’s compressor’s duty cycle is. If it’s running too long or too often, this could indicate any number of suspension issues, but a failing compressor is definitely one of them.
Soft or spongy suspension. If your air suspension feels like it has too much give, there’s likely an issue somewhere in the system. And if you’ve already checked for leaks in the air springs and air lines and haven’t found any, your compressor is a likely culprit.
Air springs for air suspensions
Although there are a lot of parts to an air suspension system, it’s the air springs themselves that do the work of keeping your vehicle at the proper ride height. Unlike static passive suspensions, air suspensions can respond to changes in the road by adjusting air pressure in these air springs—also known as air struts or air bags.
Typically, air springs are made up of a rigid strut at the bottom and a mounting bracket at the top with a flexible rubber air bag mounted in between. These air bags are made of heavy-duty rubber to resist getting punctured or torn in use.
When should you replace your vehicle’s air springs?
Because they are made of flexible materials and moving parts, your vehicle’s air springs have a limited working life. In most vehicles, the lifetime of the air springs is around 80,000 to 100,000 miles.
But that’s not a set number. Your vehicle’s air springs may last longer. They could also fail much sooner.
It’s important to repair or replace a broken air spring as soon as you notice an issue. Because the components in your air suspension are interconnected, they rely on each other to function properly. So when one air spring isn’t inflating as it should, it puts stress and strain on the rest of the system.
Signs of broken air springs
Your vehicle’s suspension warning light can let you know when you have a problem with your air springs. But as with other suspension components, once you see this light, the problem has likely become severe and you may have already started to damage other components in your suspension.
But there are ways to spot problems before they get to that point. Here are some indications that your air springs aren’t working as they should:
Sagging or leaning. If you see your vehicle sagging down or leaning to one side or corner, there’s a good chance that the air springs aren’t working properly.
Bouncy ride. Your air suspension is meant to provide a very smooth ride. If your car is bouncing while going over dips and bumps in the road, the air springs could be failing.
Drifting or swaying. Worn out air springs could result in your car not handling as “tight” as it should. If your car feels like it’s swaying or drifting going around turns, it could indicate that you have failing air springs.
How to actively check for air spring problems
If you suspect you have problems with your air springs, there are two easy ways to test whether or not there are problems.
Soap test. You can look for leaks by using a paintbrush to apply soapy water to your air springs. If you see any bubbles, you have a leak.
Bounce test. When you push the bumper down on the corner of a car with a healthy suspension, it will pop back into place quickly. If you push your car’s bumper down and it takes a long time to rise back up or bounces up and down before settling, the air spring at that corner probably has an issue.
OEM air suspension parts vs. aftermarket air suspension parts
Many people automatically assume that OEM parts are superior to aftermarket parts. But aftermarket air suspension parts like compressors and air springs can have some real advantages.
For starters, if you’re replacing parts on your air suspension, your car is likely several years old. That means that there have probably been some technological advances since your OEM suspension was made. Aftermarket suspension parts can incorporate that new technology, which is often more efficient and longer-lasting, into their designs.
Another benefit of aftermarket parts is that engineers have had time to find faults in the OEM parts and fix them. With OEM components, you’re stuck with the original design in most cases. But aftermarket air suspension parts may have improvements on the original design that fixes the reason the OEM parts failed in the first place.
Finally, many OEM air suspension parts like compressors are very expensive. And depending on how old your vehicle is, the OEM parts may be hard to find. By contrast, aftermarket air suspension parts are often much cheaper and readily available online.
What to look for in your air suspension components
While aftermarket air suspension components do have a few key advantages, not all manufacturers make quality components. Replacing your broken air suspension parts with poor quality ones could leave you in the same position just a few months down the road.
When you’re looking to buy air suspension parts, there are a few things you should look for in a manufacturer.
Precision engineering. Some companies mix and match parts that have a “good enough” fit. But a good company will take the time to engineer air suspension components specifically for a vehicle to ensure a perfect fit.
Quality materials. Cheaper materials might look the part when new, but they can easily break and fail. Reliability is important in air suspension parts, so it’s essential to get components made from high-quality materials.
Warranty. A product warranty is a good sign that the manufacturer trusts the quality of that product. That means it’s likely that you can also trust that product.
Customer support. Even with a high-quality product, you might still have questions or need help before or after your purchase. Make sure you buy from a company that offers reliable customer service so you can get the assistance and support you need, if you need it.
