FAQs— GMC Air Spring
- I am replacing a blown out air spring in my GMC this coming holiday. What precautions should I take to avoid similar problems in the future?
- What’s the effect of air springs on ride height? Can I use them to lift or lower my GMC?
- I am modifying my GMC’s suspension, and I’m torn between air springs and coil springs. Which of these two types of springs last longer?
- What are the different types of air suspension that I can consider for my GMC, and what are the advantages of each type?
- How important is an onboard air source for an air spring?
- How can I properly test my GMC air spring for leaks?
- I’ve already fitted my GMC with air springs. Can you give me some maintenance tips to make these suspension components last longer?
The air spring had most probably blown out because it was incorrectly installed. Perhaps, the rubber bellow was rubbing on a metal object while the air spring was at work. It’s also possible that the bellow was positioned too close to too much heat. When that happens, the rubber bellow is more likely to rupture. It can also be that the airline was installed on the spot where it’s exposed to extreme heat or where it comes in contact with a sharp object, causing it to eventually fail. You can avoid this situation in the future by making sure your air springs and the air suspension system in general is properly installed.
No, you can’t use the air springs to lift your car. Even if they can add to the vehicle’s height with an inch or two, the air springs are not made to do the job of raising the vehicle above its factory height. If you want to lower your GMC, go for air spring systems that are designed to replace the vehicle’s existing suspension to achieve lower stance and, therefore, better performance.
Air springs last longer than coil springs. In fact, they can last forever. It all depends on how you take care of them. If you want them to last, make sure they are properly installed and maintained. This includes regularly checking the pressure or using an onboard air system to do the air spring maintenance for you.
Air suspensions come in three types—tapered sleeve, rolling sleeve, and double convoluted. Designed for front-driven suspensions, the double convoluted air suspensions are perfect for vehicles used to carry loads. They are capable of carrying more weight than other suspension types, and they are named such because they are composed of two airbags linked together by a short stroke. For vehicles that prioritize smooth ride, such as luxury sedans, tapered sleeve air suspensions are ideal. Rolling sleeves, on the other hand, come cylindrical and are designed for the rear suspension to help vehicles that necessitate excellent handling. This is what makes the rolling sleeve perfect for sports cars.
To benefit from the adjustability offered by the GMC air springs, you must have an onboard air source. This is because with air suspension, tuning has to be done ‘on the spot’ and often involves very small changes in pressure. Since air springs have very low volume, it will be extremely difficult to deflate or inflate them using external air in very small increments when tuning. The onboard air system is made up of at least one air compressor, storage tank, and a kind of control system.
Before you check for air spring leaks, you have to find out first what component to test. If your GMC goes down after it has sat a while, turn the ignition on and observe if it will pump back up. If it does, then you may need to work on the air springs or the two solenoid seals that seal the solenoid to the air spring. However, if it doesn’t pump back, you have to determine if the compressor is running. If it is running, there can be a leak at a line connection; if it isn’t running, that can be a sign of a bad compressor.
Even if the air springs require very little maintenance, it is still important that you inspect your suspension regularly. If possible, do it once a week. Look for signs of irregular wear and tear, as well as for heat cracking on the air spring. There should be no component touching the springs or interfering with their operations. Rust buildup should also be dealt with immediately.
