Hi Tj, thanks for initiating contact. While the Monroe SET-TS171138-C is a conventional strut and spring assembly, your car currently has air suspension in the rear. Replacing the air suspension with conventional struts will require additional parts and modifications. You'll need a conversion kit specifically designed for your Expedition EL to replace the air suspension components with coil springs and struts. This kit typically includes new strut mounts, spring isolators, coil springs, and all necessary hardware. Converting the rear suspension from air to coil springs is a complex task. It's recommended to have a mechanic experienced with suspension systems perform the installation. I hope this helps. Have a nice day!

Hi James, I'm glad to assist you. No, it fits the vehicle application without the rear leveling type (not a rear suspension conversion kit). You need a conversion kit if your car originally has the rear leveling system. However, we have the rear air shocks for the rear if you would still consider sticking with the OEM comparable suspension (for the selected vehicle application).
