Product Description
Mercury Grand Marquis GS 1998-2011 Full Rocker Kit, 8 Pieces, 8"-9.125" Tapered (TH38487)
TH38487 is tagged for one trim: the Mercury Grand Marquis GS, 1998-2011, four-door sedan. The kit is eight pieces of polished stainless steel, a Full Kit that spans "from the bottom of the molding to the bottom of the door," tapering from 8" to 9.125".
GS only, on this record
The fitment tag ends with "GS." The two linked rear parts are tagged "LS, GS," but this rocker kit names only GS. The data doesn't say whether the LS shares the same lower door, so LS owners should call 877-752-3811 with a side photo before ordering.
Measure the band
A Full Kit has to match the space between the molding and the door bottom. Read it with a tape measure at the front and rear of each door. Somewhere from eight to nine and an eighth inches lines up with this record.
Linked rear parts
- RB38480: two-piece rear bumper trim accent.
- GC38480: one-piece gas door cover trim, "Full Circle, NO notch cutout."
Read each linked Grand Marquis listing for finish and fit.
The taper
The record doesn't say which end is taller. The product photos show the shape.
Material
Eight Grand Marquis GS pieces, 8" to 9.125" wide and made in the USA from polished 26 gauge 304 stainless steel, fill the area from the molding down to the door bottom on 3M automotive-grade acrylic foam tape. That tape, QAA says, will hold for a lifetime without marking the Mercury.
Tall pieces, careful hands
Each piece is eight inches or more top to bottom. Seat the top edge under the molding, hold it with painter's tape, and check the bottom edge against the door. Peel a short length of liner, press, and work across in small steps. A helper and a plastic squeegee make it easier.
Surface
Wash, dry and wipe the whole band with isopropyl alcohol. On an older sedan, look for flaking paint inside the band and repair it first.
Molding
Confirm the molding is tight along each door; it sets the top line.
Eight pieces
Not mapped in the data. Sort them with the photos and label each liner.
Afterward
Open each door fully to confirm clearance. A day before washing, then mild soap.
Sides
Keep the Grand Marquis piece positions consistent as measured.
Conditions
Dry, mild weather, out of direct sun.
Before ordering
Three checks: a year from 1998 to 2011, the GS badge, and a molding-to-door-bottom measurement in the eight to nine and an eighth range. If all three fit, the record names your car. If your sedan has had body or molding repairs, mention them when you call so we can confirm the measurement still applies.
Tools
Tape measure, painter's tape, a marker for the liners, car soap, isopropyl alcohol, lint-free towels and a plastic squeegee.
Pairing with the rear parts
The bumper accent and gas door cover are tagged LS and GS, wider than this kit's GS-only tag. If you order them together, check each listing on its own.

Installation tips: Rocker Panel Trim, Full Kit
- Unpack all 8 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.
