Important Customer "Need-to-Know" Information

Before you purchase this set, you must verify the following three points to ensure these will fit your vehicle:

1. The "MAX / L" Requirement (Most Common Mistake)

This is the #1 reason for returns on these parts. These motors are designed specifically for the extended length SUVs.

  • Ford Owners: Must have the Expedition MAX. If they have a regular Expedition, this will not fit.

  • Lincoln Owners: Must have the Navigator L. If they have a regular Navigator, this will not fit.

  • Technical Check: Please check the driver's door jamb sticker. The Wheelbase (WB) must be 131.6 inches. (The standard version is only 122.5 inches).

2. Power vs. Fixed Boards

These motors are only for vehicles equipped with factory Power Deployable Running Boards (the steps that automatically drop down when the door opens). They cannot be added to a truck that has fixed (stationary) metal or plastic steps.

3. Part Number Supersession

These replace the following part numbers: 

  • Left Side (JL1Z16A507B): Interchangeable with/Replaces JL1Z-16A507-H, JL1Z-16A507-K.

  • Right Side (JL1Z16A506J): Interchangeable with/ReplacesJL1Z-16A506-D.
