If you own a Ram 1500, you might have noticed your truck is not sitting quite right. Perhaps sagging on one side or taking longer than usual to adjust its height. These are common signs that the air suspension system might be in trouble.
First introduced in the 2013 model year as part of the fourth-generation Ram 1500, the air suspension system was a significant innovation. It improves ride comfort, load leveling, and off-road capability by automatically adjusting the truck’s height based on driving conditions. While this system offers numerous benefits, it can also develop issues over time, affecting your truck’s performance and ride quality.
In this post, we’ll explore the common problems associated with the Ram 1500’s air suspension system, including what causes these issues, how to identify the symptoms, and the best repair solutions. Whether you’re a DIY mechanic or just trying to understand what’s happening with your vehicle, this guide will provide the knowledge you need to address air suspension problems effectively.
Ram 1500 Air Suspension System — How Does It Work?
Imagine driving your Ram 1500, cruising down the highway, or tackling a rough off-road trail. As you go, your truck’s air suspension system quietly works behind the scenes, adjusting and adapting to ensure you have the smoothest ride possible.
This process begins with the air suspension control module — the system’s brain — constantly gathering information from height sensors placed at each corner of the truck. These sensors monitor the distance between the truck’s body and axles, effectively measuring the ride height. Whether you’re carrying a heavy load in the bed, pulling a trailer, or driving over uneven terrain, the sensors detect any changes in height and send this information to the control module.
Based on this data, the control module decides how much air each front and rear air springs needs. Air springs are flexible rubber bags that take the place of traditional steel springs, and they can be inflated or deflated to raise or lower the truck. When the control module signals that a spring needs more air to maintain the right height, it activates the compressor.
The air suspension compressor is like a pump, drawing in air and compressing it to a higher pressure. This pressurized air then travels through a network of air lines to reach the air springs. The valve block, a crucial part of this network, controls where the air goes. It opens and closes passages to direct the air into the specific springs that need it, or it allows air to escape when a spring needs to deflate.
As you drive, this process happens continuously and almost instantaneously. If you hit a rough patch of road, the system will adjust to absorb the shocks. If the truck is loaded with cargo, the system adds air to the springs to level the ride height. If you need to raise the truck for more ground clearance on a trail, the system will do just that.
The beauty of the air suspension system lies in its adaptability. Whether you’re hauling, off-roading, or just enjoying a comfortable drive, the system adjusts to provide the best ride possible, all without you needing to lift a finger.

Common Air Suspension Problems
While the air suspension system in the Ram 1500 is designed to provide a smooth and adaptable ride, it’s not immune to issues. Below, we explore some of the most common problems that can arise, including their causes, symptoms, and the best repair solutions.
Compressor Failure
One of the most common issues with the Ram 1500’s air suspension system is compressor failure. The compressor is responsible for generating the compressed air that keeps the air springs inflated. Over time, the compressor can become overworked, especially if there are leaks in the system that cause it to run more frequently.
Electrical issues or simply worn-out components can also lead to compressor failure. When the compressor starts to fail, you might notice loud noises coming from the rear right wheel — where the air compressor is located — or you may see that the vehicle isn’t leveling properly. A warning message on the dashboard may also indicate a problem.
The best repair solution is to inspect the compressor and replace it if necessary. If the issue is due to electrical problems, those should be addressed to prevent further damage.
Air Leaks
Air leaks are another frequent problem in the Ram 1500’s air suspension system. These leaks can occur in the air lines, fittings, or even the air springs themselves, often due to deterioration from age or exposure to debris.
When air leaks develop, the most noticeable symptom is usually one side of the vehicle sagging, as the air spring can no longer maintain the correct pressure. You might also notice that the compressor runs more frequently than usual as it tries to compensate for the lost air or that the system is slow to adjust the ride height.
To repair this issue, the first step is to locate the leak, which can often be done using soapy water to spot escaping air bubbles. Once identified, the faulty air lines, fittings, or air springs should be replaced to restore proper system function.
Faulty Height Sensors
Height sensors are crucial for maintaining the correct ride height in your Ram 1500. These sensors monitor the distance between the vehicle’s body and its axles, sending this information to the control module to adjust the air springs accordingly.
However, these sensors can wear out over time or experience electrical connection issues, leading to inaccurate height readings. When a height sensor fails, the vehicle may sit at an incorrect height, resulting in an uneven stance or triggering a suspension warning light on the dashboard.
The solution typically involves testing the sensors to confirm they are faulty and replacing them if necessary. It’s also important to check the electrical connections to ensure they are secure and functioning properly.
Control Module Issues
The control module is the brain of the air suspension system, processing input from the height sensors and other components to adjust the vehicle’s height. However, this module can experience software glitches, electrical malfunctions, or complete failure, leading to inconsistent or unresponsive ride height adjustments.
When the control module is compromised, you might notice erratic behavior in the suspension system, such as the truck not leveling correctly or persistent warning messages relating to the air suspension.
To resolve these issues, the control module may need to be reset or have its software updated. If the module itself is faulty, it will likely need to be replaced to restore full functionality to the air suspension system.
Diagnosing Air Suspension Problems
Diagnosing air suspension problems in your Ram 1500 can be straightforward with the right approach. Whether you’re a seasoned DIYer or just starting, a systematic inspection and the use of diagnostic tools can help you pinpoint the issue. Here’s a step-by-step guide to help you diagnose common air suspension problems effectively.
Visual Inspection
The first step in diagnosing air suspension issues is a thorough visual inspection. This involves looking for any obvious signs that something isn’t right.
What to Check — Look for sagging on one side, an uneven stance, or any visible damage to the air springs, air lines, or other components.
What It Tells You — If you notice that the truck is lower on one side or that an air spring looks damaged, you may be dealing with a leak or a failed component.
Test Drive
Once you’ve completed your visual inspection, it’s time to take your Ram 1500 for a test drive if it can be driven. This can reveal issues that aren’t always visible when the truck is stationary.
What to Observe — Pay attention to how the truck handles, whether it feels uneven or if there’s a delay in adjusting the ride height. Listen for any unusual noises from the compressor or air springs.
What It Tells You — Handling issues, unusual noises, or slow response in ride height adjustment can indicate deeper problems within the air suspension system, confirming the need for further investigation or repairs.
Use of Diagnostic Tools
Sometimes, a visual inspection and test drive isn’t enough to diagnose more complex issues. This is where diagnostic tools come in handy.
Tools to Use — An OBD-II scanner can be a powerful tool for detecting error codes related to the air suspension system. Specialized diagnostic tools can also provide more detailed information, such as live data and a system test.
What It Tells You — The scanner can help identify specific faults within the system, such as a faulty height sensor or a compressor issue, making it easier to target the problem.
By following these steps, you can effectively diagnose common air suspension problems before they become more serious, helping keep your Ram 1500 running smoothly.
