Magnetic Ride Control (MRC), also known as MagneRide, is a sophisticated real-time damping system that enhances ride quality and handling. Found in select Chevrolet Suburban models, it uses magnetorheological dampers that adjust their damping characteristics almost instantly in response to road conditions. Determining whether your Suburban is equipped with this advanced technology is crucial for maintenance, repairs, and even when considering aftermarket modifications. Knowing this will ensure you properly service and maintain your vehicle.
This article will guide you through various methods to identify if your Suburban has Magnetic Ride Control, covering visual inspections, documentation checks, and diagnostic procedures.

Detailed Explanations
Visual Inspection:
The most direct method involves visually inspecting your Suburban's suspension components. Look for the shocks themselves. Magnetic Ride Control shocks are typically larger than standard shocks and have a distinct appearance. Critically, they will have an electrical connector attached to them. This connector is what allows the computer to adjust the damping in real-time. Check all four wheels, as MRC is usually implemented on both the front and rear axles. Look for wiring harnesses and sensors around the shocks; these are integral to the MRC system.
RPO Code Check:
Every General Motors vehicle has a sticker that contains RPO (Regular Production Option) codes. This sticker lists all the factory-installed options for your specific vehicle. The RPO code sticker is usually located in the glove box or on the driver's side door jamb. Look for the code "Z95". If you find this code, your Suburban is equipped with Magnetic Ride Control. These codes are specific to the options installed at the factory when the vehicle was manufactured.
Dashboard Button Check:
Some Suburban models equipped with Magnetic Ride Control feature a dashboard button that allows you to switch between different suspension modes, such as "Tour" and "Sport." The button label might differ slightly (e.g., "Comfort/Sport"), but the function remains the same. Pressing this button changes the damping characteristics of the shocks, providing a more comfortable ride in "Tour" mode or a firmer, more controlled ride in "Sport" mode. If you have this button and notice a difference in ride quality when you press it, it's a strong indicator that your Suburban has MRC. Be aware that some models may automatically adjust based on driving conditions and may not have a physical button.
VIN Decoder Lookup:
Your vehicle's Vehicle Identification Number (VIN) contains a wealth of information about its original configuration. Numerous online VIN decoder websites can retrieve the build sheet for your Suburban. Simply enter your VIN into the decoder, and it will provide a list of all the factory-installed options, including whether it was equipped with Magnetic Ride Control. This method offers a definitive answer without requiring any physical inspection. Some VIN decoders are free, while others may require a small fee.
Under Vehicle Inspection:
This method requires you to physically inspect the suspension components under your Suburban. You'll need to safely jack up the vehicle and secure it with jack stands. Once the vehicle is safely elevated, examine the shocks. Magnetic Ride Control shocks typically have a distinct appearance, often being larger than standard shocks. More importantly, look for an electrical connector attached to each shock. This connector is what allows the computer to control the damping. Also, look for any markings or labels on the shocks that indicate they are part of the Magnetic Ride Control system. Pay attention to the wiring and sensors around the shocks, as these are also key components of the MRC system.
Consulting a Mechanic:
If you're unsure about any of the above methods, the easiest way to determine if your Suburban has Magnetic Ride Control is to consult a qualified mechanic. A mechanic can quickly identify the system through visual inspection and, if necessary, by using diagnostic tools. They can also verify the presence of the system by checking the vehicle's computer for MRC-specific error codes. While this method may incur a small fee, it provides a definitive answer and peace of mind.
Checking the Owner's Manual:
The owner's manual is a valuable resource for learning about your Suburban's features and options. Review the manual for information about the suspension system. It may specifically mention Magnetic Ride Control or describe the different suspension modes available. The manual might also provide information about the maintenance requirements for the system, which can further confirm its presence. This is often overlooked, but a very helpful source of information.
Diagnostic Scan Tool:
Using an OBD-II scanner that supports advanced diagnostics can help you determine if your Suburban has Magnetic Ride Control. Connect the scanner to the vehicle's OBD-II port and run a scan. Look for any error codes related to the suspension system, specifically those that mention "Magnetic Ride Control," "Real Time Damping," or "Suspension Control Module." The scanner may also allow you to view the status of the MRC system and its components. This method requires some technical knowledge and the use of a suitable diagnostic tool.
Frequently Asked Questions
How does Magnetic Ride Control work?
MRC uses magnetorheological fluid inside the shocks. This fluid contains tiny iron particles that align when a magnetic field is applied, changing the fluid's viscosity and thus the damping force.
Is Magnetic Ride Control reliable?
While MRC offers superior ride quality, it can be more expensive to repair than standard suspension systems. Reliability depends on usage and maintenance.
Can I replace MRC shocks with standard shocks?
Yes, but it requires bypassing or removing the MRC system, which may trigger warning lights and alter the vehicle's handling characteristics. An electronic bypass module is often required to prevent the warning lights.
How often should I service Magnetic Ride Control?
There is no specific service interval for MRC, but regular inspections are recommended. Check for leaks or damage to the shocks and wiring.
What are the benefits of Magnetic Ride Control?
MRC provides a smoother, more comfortable ride, improved handling, and greater stability, especially on rough roads.
Conclusion
Determining whether your Suburban has Magnetic Ride Control is essential for proper maintenance and understanding your vehicle's capabilities. By using the methods outlined in this article, from visual inspections to RPO code checks and diagnostic scans, you can confidently identify the presence of MRC. Knowing this information will empower you to make informed decisions about your Suburban's care and ensure optimal performance for years to come.
