Product Description
Ford F-150 Crew Cab Long Bed 1987-1997 Lower Door Trim, 3" Up From the Bottom, 12 Pieces (TH17321)
TH17321 gives the four-door F-150 Crew Cab long bed, 1987 through 1997, a three-inch line of polished stainless steel along the bottom of the doors and body. It's a twelve-piece Lower Kit with the note "Spans from the bottom of the door UP to the specified width," and the specified width is 3".
No molding needed as a reference
Unlike the Full Kit for the same truck, this one takes its position from the bottom edge, not from the side molding. That makes the bottom of each door and body panel your guide line. The record doesn't say whether the kit suits a truck with or without molding, so if your molding is missing or damaged, it's still worth confirming with Quality Automotive Trims.
Compared with TH17320
TH17320 is also twelve pieces for this Crew Cab long bed, but it's a 6" Full Kit that fills the band from the bottom of the molding to the bottom of the door. TH17321 covers the lower three inches. The two overlap in location, so you'd choose one or the other.
The Extra Cab kit on this sheet
TH17319 is a ten-piece 6" Full Kit for the Extra Cab long bed dually, a different truck.
Fitment
Ford F-150, 4-door, Pickup Truck, Crew Cab, Long Bed, 1987 through 1997.
Material and tape
The twelve Crew Cab long bed pieces are polished 26 gauge 304 stainless, made in the USA, fixed over the existing door surface with 3M automotive-grade acrylic foam tape. QAA states the tape will hold for a lifetime without damaging the F-150.
Bottom edges on older trucks
The lowest few inches of a truck this age can show stone chips, rust spots or old undercoating overspray. Inspect them closely. Repair rust and flaking paint and remove any overspray from where the trim will sit, then wash, dry and wipe the bottom five inches with isopropyl alcohol.
Laying out twelve
The record doesn't say how the twelve pieces are divided. Compare them with the photos and number them.
Install
Hold each run in place with the liners on before peeling. Each piece's lower edge rests on the bottom edge of its door or panel; check that the top line stays level across every joint, and open both doors. Peel and press piece by piece.
Supplies
Car soap, isopropyl alcohol, lint-free cloths, painter's tape, a tape measure and, ideally, a helper.
Timing
A warm, dry day; about a day before the first wash. Twelve pieces is a long job, so start in the morning and don't rush the later pieces.
Matching the sides
As you go, measure where each joint falls from a fixed point such as the front wheel opening, and keep those positions consistent so the truck looks even from any angle.
Care
Rinse winter salt and mud off the lower body. A non-abrasive polish restores shine.

Installation tips: Rocker Panel Trim, Lower Kit
- Unpack all 12 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.
