1997–2002 Ford Expedition 4WD Air-Suspension Conversion
For the described 1997–2002 Ford Expedition 4WD rear air-spring conversion, check both Monroe 90010C1 and 90010C2 package references. The two-box arrangement requires both parts; do not assume one box contains the complete conversion. Verify the exact vehicle and current package contents before ordering.

| Installation instructions | Included |
| Necessary hardware | Included |
Rear springs, front and rear shocks
The conversion changes the rear air springs to coils while supplying dampers for both front and rear. The “front and rear” product wording does not mean front coil springs are included. Keep the rear Loadleveler components and the rest of the documented conversion together rather than substituting ordinary rear shocks by guesswork.
Understand the change in function
Replacing rear air springs with coils changes the support arrangement. Do not assume the original automatic leveling behavior remains. Follow the exact conversion instructions for existing air equipment and any required system procedures; do not invent a warning-light or wiring treatment.
Confirm the configuration
Identify a 1997–2002 4WD Expedition with the factory rear air arrangement described. Do not extend the candidate to 2WD or later models without a separate listing. Confirm both boxes together, included hardware and installer requirements. The conversion does not increase payload or towing ratings, and safe spring work still requires suitable equipment.

Check the exact vehicle application, package contents and installation requirements for each candidate.
