Product Description
TH56660: 4-Piece Lower Door Kit, 3.75", for the Lincoln MKX 2016-2018 and Nautilus
TH56660 is a four-piece polished stainless steel Lower Kit, 3.75" wide, that spans "from the bottom of the door UP to the specified width." Its title names the 2016-2018 Lincoln MKX and the 2019-2023 Lincoln Nautilus.
Two Nautilus year ranges
The fitment has two rows. Both list the MKX 2016-2018. One lists the Nautilus 2019-2020 and the other the Nautilus 2019-2023. The record doesn't explain why the Nautilus appears twice with different end years. Owners of a 2019 or 2020 Nautilus are covered by both rows; if yours is newer than that, call 877-752-3811 before ordering and we'll confirm.
The Nautilus years
The title takes the longer Nautilus row, to 2023. The row conflict above is why we ask later Nautilus owners to check with us.
Placement
The steel starts at the bottom of each door and climbs 3.75". Four pieces for a four-door SUV, though the record doesn't say which goes where; the photos are the guide.
Stainless and tape
For the MKX and Nautilus, QAA forms four 3.75" strips in the USA out of polished 26 gauge 304 stainless, carried on 3M automotive-grade acrylic foam tape over the existing surface. According to QAA, that tape will hold for a lifetime with no harm to the Lincoln.

Preview the height
Tape a line 3.75" up from the bottom of each door. It shows the coverage, and whether anything on the door sits in the way.
Clean and dry
Wash the lower doors, rinse, and dry the bottom edges. Wipe with isopropyl alcohol.
Hang it first
Hold all four pieces with painter's tape. Check that each one follows its door's bottom edge and that the doors open without contact.
Press it on
Peel a short length of liner, set the end, and press along as you peel. Then a firm pass over each piece.
MKX spacing
Copy the first MKX run's positions on the second.
After
Wait a day before washing. Mild soap and a soft cloth.
What to tell us when you call
Your model (MKX or Nautilus), the model year and a side photo. With those, we can check the fitment rows against your SUV and, if you are buying a pillar set or the rear accents, make sure the whole order fits together. It takes a few minutes and avoids a return.
A good day for it
Choose mild, dry weather and work out of direct sun. Let a cold SUV warm up in a garage first. Allow plenty of time for the dry fit before any liner comes off.

Installation tips: Rocker Panel Trim, Lower Kit
- Unpack all 4 pieces and match each one to its position on the vehicle, using the product photos, before fitting any of them.
- Each piece mounts with 3M automotive-grade acrylic foam tape, so clean and dry the mounting surface first; the tape needs paint or trim free of dirt and wax.
- Align the piece and press it firmly into place directly over the existing surface, working along its full length so the tape bonds evenly.
- Fit one piece at a time and compare each with the product photos and the pieces already in place.
These are general tips. Follow any instructions packed with your kit if they differ.
