Selecting the Right Conversion Kit

COST-EFFECTIVE ALTERNATIVE

For vehicles equipped from the factory with an air, hydraulic self-leveling, or electronic suspension system, a failed system can be an expensive repair. Installing a Monroe® suspension conversion kit is a cost-effective alternative to replacing the original equipment system, and allows you to convert these types of suspensions to a mechanical suspension setup.

When installing a Monroe conversion kit on your vehicle, selecting the right kit for your application is imperative. For some applications, Monroe has multiple kits available – which kit you choose to install depends on the type of suspension that came on the vehicle. Please note that the issue that is causing the warning message will determine the success of the conversion kit in solving the issue. Learn the steps you should take to ensure that you select the right conversion kit for your application.

Monroe Conversion Kit

Step 1 – Determine Suspension Type

Knowing the type of suspension on the vehicle is the first step to getting the right conversion kit. Some manufacturers use codes to make it easy to identify what kind of suspension the vehicle came equipped with from the factory; for example, General Motors uses Regular Production Options (RPO) codes. (Learn more about the RPO codes that GM uses on Chevrolet and GMC vehicles.) Other ways to determine what type of suspension is on the vehicle includes physically inspecting the suspension or checking with the dealership who can use the VIN number to determine the type of suspension.

Step 2 – Identify Cause of Suspension Problem

Prior to choosing a suspension conversion kit, it is important to identify the reason why the vehicle is having issues with the suspension. While it can be tempting to install a suspension conversion kit when you see the electronic suspension light come on, the light could be triggered by a different issue. You need to know the underlying issue to ensure that you truly resolve the root cause, and if warranted, get the right conversion kit to ensure that replacing the suspension will resolve the issue.

Start by scanning the vehicle with your OBDII scanner and take note of any trouble codes that come up. Be sure to go to the Body Control module and look for air codes, height sensor not working, air shocks aren’t leveling or similar codes.
