Product Description
Lincoln MKX 2016-2018 and Nautilus Stainless Gas Door Trim (GC56660)
The title names the 2016-2018 Lincoln MKX and the 2019-2023 Lincoln Nautilus. GC56660's Fitment tab lists the Nautilus twice, though: once for 2019-2020 and again for 2019-2023. The rows overlap, so the longer range is the one to go by, and that is the span the title uses. We've flagged the repeated row for cleanup. All rows are 4-door SUVs.
Put simply, if you have an MKX from 2016 to 2018 or a Nautilus from 2019 to 2023, this gas door trim is listed for it.
For the MKX or Nautilus, this is one polished 304 stainless piece, 26 gauge, made in the USA, that mounts with 3M automotive-grade acrylic foam tape. It is not a replacement cap or replacement part: the Lincoln's own gas door must be in place, since the trim covers it.
The cross-listed parts come with useful measurements. RB56660 is a one-piece rear bumper trim accent, 2.75" wide by 42" long, and RD56660 is a one-piece rear deck accent, 0.625" wide by 46.3" long. TH56660 is a four-piece lower rocker kit at 3.75 inches that spans from the bottom of the door up to the specified width. For the pillars, there are four sets: PP56660 with four pieces, PP56661 with six, PP56662 with eight, and PP56663 with ten, which includes the front pillar behind the mirror. QAA doesn't describe what the additional pieces in the six- and eight-piece sets cover, so compare photos or call. Each sibling is tagged for the same 4-door SUV rows, without saying which nameplate.
Planning more than one piece? The gas door trim is the simplest place to start: a single flat part with no partner to line up, finished in minutes, and a preview of how polished stainless looks on your Lincoln before you move to pillars or the rocker kit.
The gas door trim installs directly over the existing surface; there's no drilling. QAA states the tape will hold for a lifetime without causing any damage to the surface of the vehicle. That bond is to the paint, so inspect the fuel door first and repair any peeling, hazy or bubbling clear coat and any edge chips. Check that the door closes flush.
When it's ready, clean the door with soap and water, rinse, and dry; follow with degreaser. Hold the trim against the closed door with the liner still attached, nudging it until the paint visible around it is uniform. Tape a couple of marks onto the body. Peel the liner, set the trim to the marks, and press hard across the face; repeat a minute later. Open the door slowly to confirm it clears. The Installation tab has the full process.
On the Lincoln, polished 304 looks bright and mirror-like, and the 26 gauge sheet keeps the overlay slim. Choose a mild, dry day and let the tape set overnight. A soft cloth and mild soap clean it; wipe off fuel drips.

Installation tips: Gas Door Cover Trim
- Confirm your vehicle still has its original gas door. This trim mounts over it and does not replace it.
- Unpack the piece and hold it in position to confirm the fit before mounting it.
- 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.
- Step back and check alignment before pressing along the full length of the piece.
These are general tips. Follow any instructions packed with your kit if they differ.
