Product Description
2017-2022 F-250 & F-350 Super Duty Regular Cab, 6.75' Bed: TH57321 Upper Rocker Kit, 10 Pieces
TH57321 is ten pieces of polished stainless steel for the 2017-2022 Ford F-250 & F-350 Super Duty 2-door Regular Cab pickup with the 6.75' bed. It's 4.5" wide and spans "from the bottom of the molding DOWN to the specified width."
Same bed, two ways of writing it
This record writes the bed as 6.75'. The linked insert kit for the same cab, MI57321 (ten pieces, 1.5"), writes it as "6 3/4' Bed." Those are the same length in two notations, so the two listings agree. We mention it so the different wording doesn't cause doubt when you compare.
Short-bed vs long-bed Regular Cab
The Regular Cab has two Upper Kits here: this one for the 6.75' bed and TH57320 for the 8' bed. Width and piece count match, so the bed length decides it. Measure the bed or check your build sheet.
Fewer listed partners
The wheel well kit (WQ57320) and window sill set (WS57320) in the linked list both name the Regular Cab with the 8' bed, not this bed. The record doesn't say whether they also fit the 6.75' bed, so call 877-752-3811 before pairing them with TH57321. Tailgate parts (RT57320, LB57320, TGH57320), the rear bumper insert set BI57320, GC57320 and the SGR57321 hood letters are listed for the pickup more broadly. Read each listing for its finish and notes.
Construction
Each of the ten Regular Cab 6.75' bed pieces is polished 26 gauge 304 stainless steel made in the USA, bonded below the molding with 3M automotive-grade acrylic foam tape over the existing surface. According to QAA, the tape will hold for a lifetime without damaging the Super Duty.
Getting the layout right
The record doesn't assign the ten pieces to door or bed. Lay them out, match the photos, and write each position on the liner.
Preparing the truck
- Wash the lower body under the molding, door and bed side.
- Rinse thoroughly and let the seam dry.
- Give the Super Duty rocker an isopropyl alcohol wipe just before fitting.
Dry fit along the molding
Hang each piece with painter's tape so its top edge sits on the molding's lower edge. Look along the side for a single straight line, and open the door.
Bonding it
Peel the liner a few inches at a time from the front end and press as you go. Give each piece a firm final pass.
Same spacing throughout
Keep the same spacing on every F-250 or F-350 piece.
Weather and washing
Work in shade on a mild, dry day, and wait a day before the first wash.
Supplies
Painter's tape, a tape measure, isopropyl alcohol, a few lint-free cloths and a marker. A second person is handy for holding the bed-side pieces on the guide while you press.
What to send when you call
The year, whether it is an F-250 or F-350, the bed length and a side photo. With those we can confirm this kit and tell you which of the linked rear and tailgate parts suit the same truck.

Installation tips: Rocker Panel Trim, Upper Kit
- Unpack all 10 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.
